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

936 *

938 *
939 * (m * x) & (2^N - 1) = floor(x/q).
940 * (m * q) & (2^N - 1) = floor(q/q).

944 * (m * q) & (2^N - 1) = 1
945 *
946 * Recall the identity that the bitwise AND of one less than a power-of-two
947 * equals the modulo with that power of two, i.e. for all x:
948 *
949 * x & (2^N - 1) = x % N

951 * Therefore:

953 * mq % (2^N) = 1
