Learning how to divide decimals is essential to learn math. It can get tricky, especially when student dealing with long decimals with many places. Here there is a step-by-step guide to help student get through this procedure.
Moving Decimals
The 1st step in decimal division is to check the divisor for decimal places. The divisor is the number that is outside of the division symbol or the 2nd number in the equation. If the divisor has a decimal, student need to move the decimal over as many places as it takes to make it a whole number. Consider the following example:
4.2512 / .125
In order to make .125 into a whole number, student must move the decimal place over 3 sots to the right to get 125. When student do this, student must also move the decimal in the dividend the number under the division sign or the 1st number in the equation, the same numbers of spaces. In this example, student would move it over 3 spaces to get 4251.2. Now the equation looks like this:
4251.2 / 125
Doing the Math
the next step is to divide the numbers as student normally would until there is no remainder. Student should get the number 340096 resting on top of the roof of the division symbol. The final step is the most important part. Student need to take the decimal in the dividend & move it directly above to the result. Now solution should read 34.0096.
Learning decimals takes some time & to practice, so make sure to provide Student with many examples. Students can always double-check their solution by multiplying the answer by the divisor to see if it equals the dividend. If it doesn't, student should know they made a mistake.
