A period at the end of a sentence means . . . it's the end of a sentence. However, a similar dot in a number doesn't have to mean the end of your math career! Learn how easy it is to divide decimals!
Here’s a trick: just ignore it and divide!
To divide a decimal number, you can use long division like you would use to solve any division problem with whole numbers.
Watch some examples of dividing decimals in the video below.
As you watch, work out the problems along with Mr. J on a piece of paper. Then, think about the steps that you took to find the answers.

Like the examples in the video, you can divide decimal numbers in real life to split money between people.
Use the steps above to solve 7.48 ÷ 2 with long division:
3 | . | 7 | 4 |
|

2 | 7 | . | 4 | 8 | |||
- | 6 | ||||||
1 | 4 | ||||||
- | 1 | 4 | |||||
0 | 8 | ||||||
- | 8 | ||||||
0 |
You can multiply the divisor by the quotient to check your answer:
1 | |||||
3 | . | 7 | 4 | ||
x | 2 | ||||
7 | . | 4 | 8 |
Correct!
You learned how to use a strategy to complete a long division problem. Remember to bring the decimal point straight up from the dividend to the quotient. Then, ignore the decimal point and divide.
