I kinda stumbled on D&D as I was browsing the net. I badly want to learn how to play one. Any interested apprenticing me?

Welcome!  Out of everything on the internet, you definitely picked one of the better things to stumble into.

Per the forum rules, you can't solicit for a specific game in Beginners.  I recommend that you go to Wanted - GMs (it stands for Game Masters, the generic term for what D&D calls the Dungeon Master) and post something there about what kind of games you're interested in learning.  It's probably worth noting that there are many editions of D&D, which all play somewhat differently.  If your previous stumblings have lead you to believe that you want to play a certain edition, specify that; and whichever you try first, if you find that you don't enjoy it as much as you want to, you can try a different edition and see if you like that one better (and ignore anyone who tries arguing about which edition is better or worse than another until you've actually had a chance to play some yourself - we all have our preferences, but you don't need our biases getting in the way of your fun).

And of course, I encourage you to also explore the many, many roleplaying games that exist that aren't D&D, because most of those are also fun.  But it might not be a bad idea to take it slow at first while you're still getting the hang of things.
