Simple answer: You can't. You can get TLDs such as .tk for free, but the only way you'll get a .com for free is if someone buys it for you, and no one here is going to do that. Namecheap sometimes does trivia days where they ask lots of quiz questions and if you answer correctly you can win credit which you can use to purchase a domain, but it isn't easy to win (and might not necessarily run any time soon) so you shouldn't rely on that.
