I don't think many models of divinity would consider this a well formed question because there would be nothing 'sub' (e,g under, beneath) divine order itself. The divine is often characterized as self-enduring, self-maintaining, and self-creating. This question is reasonable refutation of a God that is imagined to fundamentally be a 'person' who 'lives' somewhere though.

It's my feeling that the Hindu observation of infinite turtle dependence argues that the notion of divine dependence is ill-fated to begin with.
