Dividing Decimals: Learn

The procedure for the division of decimals is very similar to the division of whole numbers.

How to divide a decimal number by a one digit decimal number (e.g. 0.424 ÷ 0.8):

Place the divisor (0.8) before the division bracket and place the dividend (0.424) under it.


0.8		0	.	4	2	4

In this lesson, the divisors will all have decimal digits into the tenths. To simplify the problem, multiply both the divisor and dividend by 10 so that the divisor is not a decimal but a whole number. In other words move the decimal point one place to the right in both the divisor and dividend.


8		4	.	2	4

Bring the decimal point up directly above where it is in the dividend.

Proceed with normal long division, using placeholder zeros as necessary
