31 * Exact polynomial division of a, b \in Z_p[x_0, \ldots, x_n]
32 * It doesn't check whether the inputs are proper polynomials, so be careful
33 * of what you pass in.
35 * @param a first multivariate polynomial (dividend)
36 * @param b second multivariate polynomial (divisor)
37 * @param q quotient (returned)
38 * @param var variables X iterator to first element of vector of symbols
40 * @return "true" when exact division succeeds (the quotient is returned in
41 * q), "false" otherwise.
