This is the basis of the grade-school "casting out nines" method of
checking arithmetic. Set c=9 and you can calculate N%c fairly readily
(digit sum - I'm assuming here that the arithmetic is being done in
decimal); the sum of the remainders should equal the remainder of the
sum, but there's the inherent assumption that if the remainders sum to
something greater than nine, you digit-sum it to get the true
remainder.

(Technically the sum of the digits of a base-10 number is not the same
as that number mod 9, but if you accept that 0 == 9, it works fine.)
