Comment (by pbruin):
I ran into the following:
{{{
sage: R.<x,y>=QQ[]
sage: Q.<xx,yy>=R.quotient(x^2-y^3)
sage: xx/yy
...
ArithmeticError: Division failed. The numerator is not a multiple of the
denominator.
}}}
It would be nice if in this situation, the quotient ring could check if it
is a domain, and if so, return `xx/yy` as an element of the fraction
field.
