    We diverge from Knuth's algorithm in that we do not perform the subtraction
    from the remainder until we have determined that we have the correct

    we might have to perform multiple multiplication and comparison steps before
    the subtraction. The advantage is that it is easy to implement and ensure
    correctness without worrying about underflow from the subtraction.
