- the NUM_SIZE-DEN_SIZE least significant quotient limbs at QUOT_PTR
- and the DEN_SIZE long remainder at NUM_PTR.
- Return the most significant limb of the quotient, this is always 0 or 1.

- Argument constraints:
- 1. The most significant bit of the divisor must be set.
- 2. QUOT_PTR must either not overlap with the input operands at all, or
- QUOT_PTR + DEN_SIZE >= NUM_PTR must hold true. (This means that it's

- remainder in NUM. */
