Let $G$ be a finitely presented group. This paper describes the theory and practice of a method for obtaining information about the finite and abelian-by-finite quotients of $G$, which often allows computation further down into the group than has been possible by more traditional methods. The paper also describes the authors' software package \quotpic, which provides a user-friendly implementation of the algorithms involved in this method, as part of a complete range of facilities for computing various types of quotients of finitely presented groups. \
