904 *
905 * Choose x = q. Then:
906 *
907 * (m * x) & (2^N - 1) = floor(x/q).
908 * (m * q) & (2^N - 1) = floor(q/q).

910 * floor(q/q) = floor(1) = 1, therefore:
911 *
912 * (m * q) & (2^N - 1) = 1
913 *
914 * Recall the identity that the bitwise AND of one less than a power-of-two
915 * equals the modulo with that power of two, i.e. for all x:
916 *
917 * x & (2^N - 1) = x % N

919 * Therefore:
920 *
921 * mq % (2^N) = 1
