What do you mean by "dividing by base 5". Base 5 means there are only 4 possibly used digits : 0, 1, 2, 3 and 4. So you can get 32, 44, 10, but you cannot get 5, nor can you get 77 or 19. See what I mean ? You don't divide a number by a base, this is totally different sort of stuff.

So, do you mean that you want to divide 134 by 4, knowing you are only working on base 5 ? Or do you want to convert 4 and 134 (they are in base 10 then) into base 5 ?
