-/* Divide num (NP/NSIZE) by den (DP/DSIZE) and write
-   the NSIZE-DSIZE least significant quotient limbs at QP
-   and the DSIZE long remainder at NP.  If QEXTRA_LIMBS is
-   non-zero, generate that many fraction bits and append them after the
-   other quotient limbs.
-   Return the most significant limb of the quotient, this is always 0 or 1.
-
-   Preconditions:
-   0. NSIZE >= DSIZE.
-   1. The most significant bit of the divisor must be set.
-   2. QP must either not overlap with the input operands at all, or
-      QP + DSIZE >= NP must hold true.  (This means that it's
-      possible to put the quotient in the high part of NUM, right after the
-      remainder in NUM.
-   3. NSIZE >= DSIZE, even if QEXTRA_LIMBS is non-zero.  */
