Well according to the rules, you can only do one long rest per day. That means you have 16 hours you need to play out before you can do another one. Inside dungeons for exactly it is recommended to proceed time in minutes. Some actions like searching a whole room takes several minutes, but still, you will get at least say 200 rounds outside combat before the day comes to an end. Unless you do short rests in between to proceed some time. But that's still a lot of sitting around and waiting in enemy territory just to be able to take a long rest again. Or alternatively, the group enters the dungeon, does 2-3 battles, then travels back the next town, rests, goes back to the dungeon, does another 2-3 battles, leaves again... hmm it seems boring to me. And reduces the excitement of having to conserve resources and being scared of getting out alive.
There's nothing that says the players can't just say, "we wait for several hours and then take a long rest." We don't have to spend table-time tracking every 10-minute turn players spend in the dungeon if they don't plan to do anything specific during that time. Instead, it falls on the DM to decide (likely through wandering monster rolls), if the players are accosted while camped out reading and playing cards in Room 17 of the dungeon.
This isn't going to work well in small, concentrated dungeons, such as lairs, forts, etc, but in larger dungeons, there's definitely the possibility of spending 24 hours without serious interruption.
I've also had groups withdraw just beyond the entrance of a dungeon and camp for the night. When they come back, new traps have been put in place, fortifications have been improved, and sometimes monsters have even gone for reinforcements. But this may be preferable to soldiering on with low hit points and no spell slots.
Differing adventures have really varied. I've run adventures with lots of minor combats, so closer to the 6-8 benchmark, and then other adventures with larger, more draining combats that tended to grind a group down much more quickly. So maybe 3-5 on average? I've also found that I rarely have more than 3 or 4 combat encounters in one session, and I think players are often more interested in trying to long rest at the beginning or end of a session.
Of course, I generally roll 4 random encounter checks for a long rest in hostile territory, so there's a very good chance that a long rest will be interrupted, sometimes more than once in a night.
