Understanding Decimal Division

When dividing decimals, it's essential to follow a specific set of steps to ensure accuracy. Decimal division can be a bit tricky, but with practice, you'll become more comfortable with the process. In this article, we'll focus on finding the quotient of two decimal numbers, specifically $1.602 \div 0.18$ . We'll break down the steps involved in decimal division and provide a clear explanation of how to arrive at the correct answer.

Step 1: Line Up the Decimals

To begin, we need to line up the decimal points of the two numbers. This will help us keep track of the place values and ensure that we're performing the division correctly.

Step 2: Add Zeros

Since the divisor (0.18) has only two decimal places, we need to add zeros to the dividend (1.602) to make it easier to divide. We'll add zeros after the decimal point until we have a total of two decimal places.

Step 3: Divide the Numbers

Now that we have the numbers lined up and the dividend has the correct number of decimal places, we can begin the division process. We'll divide the first two digits of the dividend (16) by the divisor (18).

Step 4: Bring Down the Next Digit

Since we've divided the first two digits of the dividend, we need to bring down the next digit (0) and continue the division process.

Step 5: Continue the Division Process

We'll continue dividing the numbers, bringing down the next digit each time, until we've divided all the digits of the dividend.

Step 6: Write the Quotient

After completing the division process, we can write the quotient by combining the results of each step.

Conclusion

In this article, we've walked through the step-by-step process of dividing decimals. By following these steps, you can find the quotient of two decimal numbers with ease. Remember to line up the decimal points, add zeros as needed, and continue the division process until you've divided all the digits of the dividend. With practice, you'll become more comfortable with decimal division and be able to find the quotient of any two decimal numbers.
