Polynomial arithmetic modulo prime powers
I'm trying to do some operations with polynomials over $Z/p^nZ$ and I'm stuck on some basic things:
1) Is it possible in SAGE to long divide two polynomials in $Z/p^nZ[x]$?
2) Is it possible in SAGE to factor a polynomial in $Z/p^nZ[x]$?
Am I missing something about the basic functionality of (1)? Is this really something that I need to program myself??
