Does quantity/rarity on items from a character applies first in the queue for quant mult and rarity?

OK.

My problem with understanding rarity and quantity is as follows.


Lets say on a map drops one divination card from a monster (strongbox, mob, barrels etc) what is the rolling for that item when it comes to rarity and quant.

In my mind it should apply in a queue and it should start with rarity items on character, then multiply with scarabs and fragments, followed by map quant and rarity, then with whatever mod (delirium etc) you have on it.

Is there someone that can clarify how this works? Does the rarity/quantity apply first on that queue?
