Let us suppose that we want to put the FR edge piece into its proper place. First find the piece.

Turn the whole cube so that the offending piece is at the FR position, apply B'U·R2U2R2U2R2U2·U'B (which moves the piece to BU), then turn the whole cube to where it was. So we have the FR piece in the U face.
