The procedure for the division of decimals is very similar to the division of
whole numbers. Make the divisor into a whole number by multiplying both it and
the dividend by the same number (such as 10, 100, 1000 etc.). An easy way to do
this is to move the decimal point to the right end of the divisor and move the decimal
point of the dividend the same number of places.
How to divide a four digit decimal number by a two digit decimal number (e.g. 0.424 ÷ 0.8).
- Place the divisor before the division bracket and place the dividend (0.424) under it.
- 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
- Proceed with the division as you normally would except put the decimal point in
the answer or quotient exactly above where it occurs in the dividend. For example:
