Definition of long division for Students. : division in arithmetic that involves several steps that are written out.
Division is multiplication backwards. For example: 8 Ã· 4 = 2 because 4 x 2 = 8. Remainders are what you get when you can't multiply the number outside the box with the number inside the box. For example, 26 Ã· 5 = 5 with a remainder of 1 because 5 x 5 = 25. So, there is only 1 number left after you divide evenly.
