You give it to Steven. He is in the very back of granite cave. You may want to get flash first because a lot of the cave is dark

After delivering the letter to Steven, go to Rubusto or whatever city and talk to the guy who sent you to give the letter to him. He'll give the exp share to you.

After you deliver the letter from mr. Stone in rostboro city go back and he will give it to you

steven is in Dewford cave, when you give him the letter, in return he will give you the TM steel wing. when you go through dewford cave it is easier to get the HM flash first hope i helped :)
After you give Steven the letter go back and the President guy will give one to you:)
