New description:
{{{
sage: cm = sage.structure.element.get_coercion_model()
sage: cm.bin_op(GF(5)['x'].gen(), 7, operator.div).parent()
Fraction Field of Univariate Polynomial Ring in x over Finite Field of
size 5
}}}
The problem is that we are not finding the inverse because we are passing
to the fraction field of ZZ before coercing to GF(5).
