The right shift operator will divide by powers of 2. That's the only shortcut I use. Here are a few notes on Binary Division which might be fun.

A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi

Implement binary long division. Sure, regular base 10 long division uses a divide operation, but since the binary equivalent needs to arrive at either a 0 or a 1, you could get away with an if statement.

This algorithm would be O(log product), while the subtraction algorithm would be O(result).
