[Lord of the rings] Gandalf and the Balrogs fall

Now I haven’t read the books but I was talking to a friend about FotR and we started talking about when Gandalf does his skydive with the Balrog. Now I could be mistaken but doesn’t it show a scene of Gandalf up on a snowy tower? How did he get there from falling down Moria? My friend couldn’t remember if it was explained or even in the books in the first place.

They battled all the way to the top. When they land in the ocean at the bottom of the world, the balrogs fire is extinguished, and it turns into a slimly and grosse being. Gandalf then chases it all the way to the top, becasue there is a staircase that goes from the bottom to the top. When they reach the top, the balrogs fire reignites and they battle again.
