How do you tell your location to 999?

I like walking, I always walk since I don't have a license yet, and when I come home after a night out, it's always just me. I take random buses, etc. If I can't get the bus on the exact route, I try to walk home. If I have data, I use maps; if not, I just use signs and ask people walking dogs, etc. So most times, I really don't know where I am, like I just walk. So if something happens to me, like an emergency situation, and I want to contact 999 and get an ambulance or police or something, how do I tell them my exact location? Can they track my exact location?
