911 * Let q represent the number we would like to divide by.

913 * By definition of a magic divisor for N-bit unsigned integers (a number you

920 * for our purposes (instanced arrays).
921 *
922 * Choose x = q. Then:
923 *
924 * (m * x) & (2^N - 1) = floor(x/q).
925 * (m * q) & (2^N - 1) = floor(q/q).

929 * (m * q) & (2^N - 1) = 1
930 *
931 * Recall the identity that the bitwise AND of one less than a power-of-two
932 * equals the modulo with that power of two, i.e. for all x:
933 *
934 * x & (2^N - 1) = x % N

938 * mq % (2^N) = 1
