No. We do not need 'mod'. At most we need FT_DivFix.
The suggested use of div is as follows from Type1 specs:
"If additional precision is necessary, expressions such as 145 10 div
may be used to provide a number (in this case, 14.5) that cannot
be expressed directly in the charstring format."
This worked so far: src/psaux/t1decode.c:1332.
