Question

How to divide large decimals by whole numbers step by step.

Answer 1

To divide a large decimal by a whole number, ignore the decimal at first and divide as if both were whole numbers. The decimal in the answer is placed the same number of digits from the end as were after the decimal in the original problem.

Step-by-step explanation:

To divide large decimals by whole numbers, the steps are straightforward. Let's illustrate this with an example:

1. Suppose you're dividing 75.36 by 4. Firstly, disregard the decimal and just divide the number as if they were whole. So, 7536 ÷ 4 = 1884.
2. Then, count how many numbers are after the decimal in the original number (in this case, two: 75.36).
3. Place the decimal in the answer (1884) the same number of places from the right, resulting in 18.84.

Note that when dividing by powers of 10, one must move the decimal point to the left by the number of zeros in the power of ten.

Also, keep in mind that in multiplication and division, the product or quotient should contain no more digits than that in the factor containing the least number of significant figures.
