ABACUS – DIVISION OF DECIMALS


Convert the dividend and the divisor into whole numbers. While converting the divisor and
the dividend, both the numbers should be multiplied by the same number (10 or 100 or
1000). The decimal multiplication procedure will not apply here.


Consider this example : (^162). 25.^5
Here the divisor has two decimal digits. Hence multiply both the divisor and the dividend
by 100 to convert them as whole numbers.
You will get 6250 and 125 respectively because you multiplied both the dividend and the
divisor by 100 (since you have a maximum of two decimal digits in the divisor). Follow the
normal procedures for getting the quotient. After dividing you get 50 as the answer.
