pdivi(f,F);
poly f: the polynomial to be divided
ideal F: the divisor ideal

Return:
A list (poly r, ideal q, poly m). r is the remainder of the pseudodivision, q is the set of quotients, and m is the coefficient factor by which f is to be multiplied.

Note:
pseudodivision of a poly f by an ideal F in @R. Returns a list (r,q,m) such that m*f=r+sum(q.G), and no lpp of a divisor divides a pp of r.
