As just as one illustration of the possible importance of long division, I was teaching randomization using SPSS the other day and had to spend a little time explaining the idea of a remainder in order to explain how modulus arithmetic works. The modulus operator is used to generate repeated cycles when preparing an experimental design (i.e., 1 2 3 4 1 2 3 4 ...). Mod(x, y) is the remainder when x is divided by y (e.g., 5 mod 4 = 1). There may be other situations when remainders (i.e., long division?) are important? And it perhaps should be pointed out that there is a considerable psychological literature on mathematics, including mental calculation algorithms (e.g., Campbell & Charness's work on a squaring algorithm with young and old participants).
