How to upload a game to the internet

I would like to please know a simple way to upload a game I made with unity, for people to download. I am kind of a noob in this but I am proud of the work I have done and I would like to share it. (Free of charge of course)

You can simply go to file>built settings and change your platform to unity web game. It will create a html file with your game embedded into it, along with some unity links(which can be removed easily). How you ago about hosting it, can really be anyway that you have to ability to upload files to your site. Hope this helps you out.
