Comment (by vdelecroix):
Another option seems to flatten the polynomial ring in order to make
singular happier
{{{
sage: R.<a,b> = QQ[]
sage: P.<x,y,z> = R[]
sage: p0 = a*(x+y)*x^2
sage: g = x + y
sage: p0.quo_rem(g)
Traceback (most recent call last):
...
TypeError: no conversion of this ring to a Singular ring defined
sage: Pflat.<x,y,z,a,b> = QQ[]
sage: p0 = Pflat(str(p0)) # conversion hack ;-)
sage: g = Pflat(g)
sage: p0.quo_rem(g)
(x^2*a, 0)
}}}
