Short division is useful when the student knows his/her multiplication and subtraction facts and can determine remainder mentally. Here is an example: Divide 6738 by 8. _________ 8 / 6 7 3 8 8 goes into 67 eight times and the remainder is three. Carry the 3 to the right. 8 goes into 33 four times and the remainder is 1. Carry the remainder to the right. 8 goes into 18 Two times and the remainder is 2. The answer is 842 with a remainder of 2. It is almost the same as long division except you don't show your subtractions and you do the math in your head. Thus you need to know math facts. When I went to elementary school, short division was taught before long division. I think it should still be taught. For example, if you are trying to reduce a fraction such as 48/56 it helps you if you can do the division in your head. Of course, you can do that if you know your math facts.
