Numbers: Getting to grips with division

7 Dividing when you have to carry

If the number you are dividing by does not go exactly (with no remainder) into the digit you are dividing into, you need to do something called carrying.

Say you want to divide 952 by 7. The process is basically the same as in the previous section. First write it down on paper. Then, to do the calculation, you take each digit from the number being divided in turn, starting with the one on the far left, and see how many times the dividing number, 7 in this case, goes into it. The calculation is shown below. Click on each step in turn to see how carrying is done.

In your head, as you do this calculation, you’ll probably be thinking something like ‘Seven into 9 goes once, leaving 2 over. Seven into 25 goes 3 times (because 3 sevens are 21), leaving 4 over. Seven into 42 goes 6 times (because 6 sevens are 42)’.
