D.7.5.12 RemainderMain

Procedure from library zeroset.lib (see zeroset_lib).

Usage:

RemainderMain(f, g); where f,g are polynomials

Purpose:

compute the remainder r s.t. f = g*q + r, deg(r) < deg(g)

Return:

poly

Assume:

basering = Q[x,a] and ideal mpoly is defined (it might be 0), this represents the ring Q(a)[x] together with its minimal polynomial.
