How to Divide Decimals
If you can move a dot and solve a simple division problem, then you can divide decimals as well as any math whiz.
Instructions
- Step 1: Change the divisor Change the divisor – the number by which the other number, the dividend, is divided – to a whole number by moving the decimal point to the right.
- Step 2: Move the decimal of the dividend Move the decimal point of the dividend to the right the same number of places as you moved the decimal in the divisor.
- TIP: After moving your decimal point to its new position, if the dividend is not a whole number, you can still complete your computation.
- Step 3: Write the division problem Write your division problem with the divisor outside the long division symbol, and the dividend inside of it.
- Step 4: Place zeros in any empty places Place zeros to the right of the decimal point, in any "empty" places created by moving the decimal place of the dividend.
- Step 5: Place a decimal above the decimal point in the dividend Place a decimal directly above the decimal point in the dividend – on top of the long division symbol.
- Step 6: Divide Divide using normal division to complete your computation.
- FACT: Did you know? A book written in 1579 by the mathematician Francois Viete introduced the modern base-10 decimal system to the world.
