Long division - divide decimals by 1 digit number


Dividing decimals

We've seen how we can divide whole numbers using long division, and how we set our work out going down the page. We show each step, so that we can see what we've allocated, or shared, and what we have left.

With decimals, it's exactly the same process! The only difference is that our digits may be in columns with tenths, hundredths etc., rather than units, tens and hundreds. Let's see how we can solve them, first by thinking about what our answer might be.

In Video 1, we start with a simple example, dividing by $2$2. This allows us to think about estimating our answer, since dividing by $2$2 is the same as finding half of a number.
