  We present a general framework to systematically study the derivative
expansion of asymptotically safe quantum gravity. It is based on an exact
decoupling and cancellation of different modes in the Landau limit, and
implements a correct mode count as well as a regularisation based on
geometrical considerations. It is applicable independent of the truncation
order. To illustrate the power of the framework, we discuss the quartic order
of the derivative expansion and its fixed point structure as well as physical
implications.
