### 2.33.1 Division by increasing power order : `divpc`

`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 at order *n* of
*A*/*B* in the vicinity of *x*=0.

Input :

`divpc(1+x``^`

`2+x``^`

`3,1+x``^`

`2,5)`

Output :

`-x``^`

`5+x``^`

`3+1`

Note that this command does not work on polynomials written
as list of coefficients.
