• Calculating using short division

Sometimes division calculations involve numbers that are too big for you to calculate mentally. In
these situations you need to use a written method.

If you are dividing a number by a single digit, you can use short division.

Here's how you can use short division to work out 345 ÷ 3.
With short division, always begin with the highest value digit. Here it's the hundreds.

1. In this example, when you divide the tens, there are some left over.
Anything left over, moves to the next column to the right.
2. In this example, the left over ten moved into the ones column, to make
15. The final answer is 115.
