---  Using a scaled divide which truncates and returns a remainder R,
---  another E trailing digits can be calculated by computing the value
---  (R * (10.0**E)) / Z using another scaled divide. This procedure
---  can be repeated to compute an arbitrary number of digits in linear

---  a possible carry propagating to the more significant digits, to
---  ensure correct rounding of the unit in the last place.

---  An extension of this technique is to limit the value of Q to 9 decimal
---  digits, since 32-bit integers can be much more efficient than 64-bit
---  integers to output.
