ELI5:Voyager 1 is the farthest spacecraft traveled from Earth, where does it find all of that fuel and how can scientists still manage to control it?

Question number 1: I understand that the Voyager 1 is a probe and there is no gravity or air resistance in space so you can move a great distance with little force but it still need the fuel to propel itself or change direction from time to time and it has been traveling for a very long time, so where does it find all that fuel?  
Question number 2: the Voyager has gone out of the solar system, which is VERY far away, how can they still manage to control it? what method did they use?

It has very little if any fuel left. It is simply just flying through space. You said it yourself there's no air resistance. Now that it's moving it doesn't need any fuel to keep moving. They dont change direction ever. They don't really do much control anymore. They just receive data from some of the sensors. If they do want to control it they have to issue the commands in sequence so that voyager can execute them automatically once it receives them.
