The only problem with dividing a recipe is: say it serves 4 people and requires one onion, a clove of garlic, a pepper and you need only a little water too cook the whole thing (example)...firstly the problem lies with having to use quarter of an onion etc, and then if you cooked a quarter of that lot for the time you need to cook it for it'll dry out if you use even less water/stock for it.
With meat recipes if it serves 4 and you only need to cook a quarter of that amount I don't know how long the thing needs to take to cook.
Also you'd still have to plan ahead to defrost a casserole with meat in it from the freezer the night before, and what if you want something else when you get back from work the next day? I'm really not a fan of doing that, I just want to be able to prepare something for myself, whenever I like.
