How to divide a column

Division in a column is always useful - it is possible both to find this way the rest of integer division, and to bring process of division to the necessary sign after a comma.

Instruction

1. Let's begin with record of a dividend and a divider. At first we write down a dividend, to the right of it it is written divider which separates a corner.

2. Now it is necessary to define an incomplete dividend, the number formed by several consecutive figures of a dividend so is called. For this purpose we consider a dividend, since the senior categories, at first the first figure, then the number formed by the first and second figure and so on until the incomplete dividend does not become more divider. We estimate how many times a divider contain in an incomplete dividend, and we write this number under a divider. We multiply by it a divider and it is deductible turned out from an incomplete dividend. If you correctly picked up number, then the rest will be less divider. If you were mistaken and received the rest, bigger a divider, then increase this number by unit, the two and so on, as at usual division.

3. Demolish the following figure of an initial dividend by the rest of the previous division and continue division. In our example on this step it is possible to finish integer division and to write down the answer in a look ""56 whole and 23/25"". If it is necessary to continue division, then it is necessary not to forget to put a comma in the turning-out private.

4. We take down by the figure rest, located after a comma. In an example an integer therefore we take down zero. We continue division in the same way, we will not receive zero in the rest yet. Now it is possible to write down the answer ""56.92"".
