the mining fee is divided proportionally by the hash of the miners right? if you have 1/10 of the hash you get 1/10 of the total fee?
No. Only one party (the one mining the block) will get 100% of the money.
wait, how it work with pool then? it must be divided in the end, or the pool get all the money from fees?
The pool gets all the money (25 BTC+fees) and can then distribute the money to its users. Or not, depending on the pool operator and its rules. This is not part of the bitcoin protocol.
