How to Divide Decimals
Put the point straight up, or make a decimal divisor whole first.

How to do it
- Dividing by a whole number, divide as usual.
- Put the point in the quotient straight above the point.
- Dividing by a decimal, make the divisor whole first.
Teaching tip
Have your student check by multiplying. 1.92 × 4 should give back 7.68. This sheet is aligned with Common Core 5.NBT.B.7.
About this chart
7.68 ÷ 4 worked on a long division grid with the decimal point carried straight up, and 3.6 ÷ 0.4 and 1.5 ÷ 0.05 turned into whole-number divisors.
What kids practice
Fifth graders extend decimals to thousandths, the third place after the decimal point. They read and write decimals in word and expanded form, compare and order them, and round them to the nearest whole, tenth or hundredth. Then they add and subtract decimals by lining up the decimal points, so each digit lands in the right place, and filling empty places with zeros. Last, they multiply and divide decimals to hundredths, working like whole numbers and using place value and estimates to place the decimal point.
Watch for
- Thinking a decimal with more digits is always bigger, like 0.407 > 0.47.
- Lining up the last digits instead of the decimal points.
- Forgetting that a whole number like 7 has a decimal point at the end (7.00).
- Rounding by looking at the wrong digit, or forgetting to carry when rounding a 9 up.
- Lining up the decimal points when multiplying, instead of counting decimal places.
- Leaving out the decimal point in the quotient, or putting it in the wrong place.
It's free to print, as many copies as you need. See the full decimal operations guide for 5th grade.
