Introduction

Long division is a mathematical technique used to divide one number by another and find the quotient and remainder. It is a crucial concept in mathematics, particularly in arithmetic and algebra. In this article, we will focus on calculating the result of 7234 ÷ 48 using the long division method.

Understanding the Long Division Method

The long division method involves dividing a dividend (the number being divided) by a divisor (the number by which we are dividing). The process involves several steps, including:

Dividing the dividend by the divisor: We start by dividing the first digit of the dividend by the divisor. If the result is a whole number, we write it down as the first digit of the quotient. If the result is not a whole number, we write down the whole number part and multiply the divisor by the whole number part. We then subtract the product from the dividend.
Bringing down the next digit: We bring down the next digit of the dividend and repeat the process of dividing by the divisor.
Continuing the process: We continue this process until we have divided all the digits of the dividend.
Finding the remainder: The remainder is the amount left over after we have divided all the digits of the dividend.

Calculating 7234 ÷ 48 Using the Long Division Method

To calculate 7234 ÷ 48 using the long division method, we follow the steps outlined above.

Step 1: Dividing the First Digit

We start by dividing the first digit of the dividend (7) by the divisor (48). However, since 7 is less than 48, we cannot divide it directly. We write down 0 as the first digit of the quotient and multiply the divisor (48) by 0. We then subtract the product (0) from the dividend (7). The result is still 7.

Step 2: Bringing Down the Next Digit

We bring down the next digit of the dividend (2) and repeat the process of dividing by the divisor. We divide 72 by 48, which gives us 1 with a remainder of 24.

Step 3: Continuing the Process

We write down 1 as the next digit of the quotient and multiply the divisor (48) by 1. We then subtract the product (48) from the remainder (24). The result is 24 - 48 = -24. However, since we cannot have a negative remainder, we add 48 to -24, which gives us 24.

Step 4: Bringing Down the Next Digit

We bring down the next digit of the dividend (3) and repeat the process of dividing by the divisor. We divide 243 by 48, which gives us 5 with a remainder of 3.

Step 5: Continuing the Process

We write down 5 as the next digit of the quotient and multiply the divisor (48) by 5. We then subtract the product (240) from the remainder (3). The result is 3 - 240 = -237. However, since we cannot have a negative remainder, we add 48 to -237, which gives us 3.

Step 6: Bringing Down the Next Digit

We bring down the next digit of the dividend (4) and repeat the process of dividing by the divisor. We divide 34 by 48, which gives us 0 with a remainder of 34.

Step 7: Continuing the Process

We write down 0 as the next digit of the quotient and multiply the divisor (48) by 0. We then subtract the product (0) from the remainder (34). The result is still 34.

Step 8: Finding the Remainder

The remainder is the amount left over after we have divided all the digits of the dividend. In this case, the remainder is 34.

Conclusion

Using the long division method, we have calculated the result of 7234 ÷ 48 as 150 with a remainder of 34. This result can be expressed as a mixed number: 150 34/48.

Introduction

Long division is a mathematical technique used to divide one number by another and find the quotient and remainder. It is a crucial concept in mathematics, particularly in arithmetic and algebra. In this article, we will answer some of the most frequently asked questions about long division.

Q: What is long division?

A: Long division is a mathematical technique used to divide one number by another and find the quotient and remainder. It involves dividing a dividend (the number being divided) by a divisor (the number by which we are dividing).

Q: How do I start a long division problem?

A: To start a long division problem, you need to write the dividend (the number being divided) on top of a line, and the divisor (the number by which we are dividing) below it. You then divide the first digit of the dividend by the divisor, and write the result below the line.

Q: What is the quotient in long division?

A: The quotient in long division is the result of dividing the dividend by the divisor. It is the number that is obtained by dividing the dividend by the divisor.

Q: What is the remainder in long division?

A: The remainder in long division is the amount left over after we have divided all the digits of the dividend. It is the number that is left over after we have divided the dividend by the divisor.

Q: How do I calculate the remainder in long division?

A: To calculate the remainder in long division, you need to subtract the product of the divisor and the quotient from the dividend. The result is the remainder.

Q: What are some common mistakes to avoid in long division?

A: Some common mistakes to avoid in long division include:

Not lining up the digits correctly: Make sure to line up the digits of the dividend and the divisor correctly.
Not checking the work: Check your work regularly to ensure accuracy.
Not using the correct method: Use the correct method for long division, which involves dividing the first digit of the dividend by the divisor, and then bringing down the next digit.
