divpc takes three arguments : two polynomials
expressions A, B depending on x,
such that the constant term of B is not 0, and an integer n.

divpc returns the quotient Q of the division of A by B
by increasing power order, with degree(Q)≤ n or Q=0.
In other words, Q is the Taylor expansion of order n of
A/B in the vicinity of x=0.
