Well, the normal way to check a division problem is with multiplication... if you divide 21 by 7 and come up with three, then you check that by multiplying 7 and 3, to get 21. But if you're on an abacus or something, I suppose you could say, "I came up with a result of three, which means three sevens", and then add 7 + 7 + 7 to get 21.
