For the division:
yyy / xxxxx
the following
steps are taken: First the number
yyy is extended with
zeros on the right until it is larger than the number
xxxxx (with
note being taken of the change in the power of ten that this implies).
Thus, in this example,
yyy might become
yyy00.
Traditional long division then takes place. This might be written:
zzzz
┌─────────
xxxxx │ yyy00
The length of the result (
zzzz)
is such that the rightmost
z is at least as far right as
the rightmost digit of the (extended)
y number in the example.
During the division, the
y number is extended further as
necessary. The
z number may increase up to NUMERIC DIGITS+1
digits, at which point the division stops and the result is rounded.
Following completion of the division (and rounding if necessary),
insignificant trailing zeros are removed.
