It's very difficult. The reason is the quest records video in a variable framerate format, you won't notice this during playback usually but because the audio isn't also recorded at a variable rate it makes the resulting streams basically impossible to match up in any sensible way. 

I've made a whole bunch of videos recorded on my Quest for this place and I sincerely hope you don't mind cutting your audio up into tiny chunks and syncing each one manually, because you're not going to find any magical sweetspot where everything just matches. 

Just do as well as you can friendo.
