MAINT: Unify polynomial division functions
These division functions are all the same - the algorithm used does not care about the basis.
Note that while chebdiv and polydiv could be implemented in terms of this function, their current implementations are more optimal and exploit the properties of a multiplication by a basis polynomial.
