Introduction

In mathematics, division is a fundamental operation that involves finding the quotient and remainder when a number is divided by another number. The quotient is the result of the division, while the remainder is the amount left over after the division. In this article, we will explore how to find the quotient and remainder when a number is divided by another number using the formula: a = bq + r, where a is the dividend, b is the divisor, q is the quotient, and r is the remainder.

Understanding the Formula

The formula a = bq + r is a fundamental concept in mathematics that helps us find the quotient and remainder when a number is divided by another number. In this formula, a is the dividend, b is the divisor, q is the quotient, and r is the remainder. To find the quotient and remainder, we need to divide the dividend by the divisor and find the result.

Finding Quotient and Remainder

To find the quotient and remainder, we can use the following steps:

Divide the dividend by the divisor to find the quotient.
Multiply the divisor by the quotient to find the product.
Subtract the product from the dividend to find the remainder.

Example 1: Finding Quotient and Remainder

Let's consider an example to find the quotient and remainder when a = 171 and b = 16.

Step 1: Divide the dividend by the divisor

To find the quotient, we need to divide the dividend (171) by the divisor (16).

171 ÷ 16 = 10.69

Step 2: Multiply the divisor by the quotient

To find the product, we need to multiply the divisor (16) by the quotient (10.69).

16 × 10.69 = 171.04

Step 3: Subtract the product from the dividend

To find the remainder, we need to subtract the product (171.04) from the dividend (171).

171 - 171.04 = -0.04

Since the remainder is negative, we can add the divisor (16) to the remainder to find the actual remainder.

-0.04 + 16 = 15.96

However, since the remainder should be less than the divisor, we can round down the remainder to 15.

Therefore, the quotient is 10 and the remainder is 15.

Example 2: Finding Quotient and Remainder

Let's consider another example to find the quotient and remainder when a = 253 and b = 13.

Step 1: Divide the dividend by the divisor

To find the quotient, we need to divide the dividend (253) by the divisor (13).

253 ÷ 13 = 19.46

Step 2: Multiply the divisor by the quotient

To find the product, we need to multiply the divisor (13) by the quotient (19.46).

13 × 19.46 = 253.18

Step 3: Subtract the product from the dividend

To find the remainder, we need to subtract the product (253.18) from the dividend (253).

253 - 253.18 = -0.18

Since the remainder is negative, we can add the divisor (13) to the remainder to find the actual remainder.

-0.18 + 13 = 12.82

However, since the remainder should be less than the divisor, we can round down the remainder to 12.

Therefore, the quotient is 19 and the remainder is 12.

Conclusion

In conclusion, finding the quotient and remainder when a number is divided by another number is a fundamental concept in mathematics. The formula a = bq + r helps us find the quotient and remainder when a number is divided by another number. By following the steps outlined in this article, we can find the quotient and remainder when a number is divided by another number.
