You are looking at the wrong part of the table.
This discussion is about DECIMAL operands.
what I wrote is correct for such.
See Table 15 top entry, for ANS rules for division;
Table 16 top entry, for IBM rules.

It doesn't depend on whether IBM rules or ANS rules are in force.
What I said it correct for IBM rules also.
The result is always an integer.
See Table 16.
When the operands have maximum precision, the result is integer.
The formulas for precision and scale factor are exactly the same.
