Perhaps not necessarily an entire chapter, to keep my TV series comparison, there's some arc that need two episodes.
The important part, whatever how often, or not, you'll update, and how big, or small, those updates will be, is to offer something coherent as independent entity. And I say "coherent", not "comprehensible", because obviously it will often make no real sense without the previous updates, and don't really mean something without the future updates. But at least there's a whole part of the story and it feel complete. Something was to do (on more than one action), and it was done.
When a TV series need two episodes, it still don't left you in the middle of something. Each episode is a story by itself, and while you understand that there's still something missing, you don't feel like if you were interrupted in the middle of nowhere.
To take a thriller as example, the first episode will be dedicated to the investigation, and it will end when you'll know who the killer his. Then, the second episode will be dedicated to the track of this master of disguise, and obviously end when he'll be caught.
Reported to an adult game, it can be something like, "adventure of the day: tonight I'll take my girl on a romantic date". The first update will be the MC searching the perfect place for his date. It will left the player with something missing, but also with something fully accomplished. Then the second update will be the date itself. You'll be splitting what is a single day/episode into two updates, while keeping each update coherent.
This opposed to a morning/afternoon/evening three updates release, where you'll still be in the middle of MC's search for the perfect place at the end of the first update. And where MC will already have picked up his girl when the second update will end.
