 Note: 16-bit divide for 65816 16-bit could be implemented as a reciprocal multiply, making it faster. It might also be possible to use reciprocal multiply to implement larger divides by using larger tables, computing an approximation and then fix any quotient errors after computing the remainder. I haven'​t investigated if it would be faster than the simple radix-2 divides though. Note: 16-bit divide for 65816 16-bit could be implemented as a reciprocal multiply, making it faster.
