    The answer to that question is that the fastest way to divide
by 7 is to use the divide instruction.   You'd have to go down
to a really old 8-bit microprocessor like the Intel 8051 to
find something where bit-twiddling like that pays off.

    And no way would this be a win in Python, which is
interpreted.
