Set up the equation. On a piece of paper, write the dividend (number being divided) on the right, under the division symbol, and the divisor (number doing the division) to the left on the outside. ...
So, for example, 7 divided by 3. -- 3x2=6 so the remainder would be 1, if you get a remainder like this you just have to add a decimal point and add a zero after the point, you bring down the zero and try to divide that, so the answer would be 2.3. Hope this helped.
