000 webhost.com etc etc there are tons of it, but why do you want to get a free hosting? why dont' you try for a cheap hosting like 15-20$ a year, including domain etc? so its actually free for you.
You can directly use wordpress. They allow you to have free hosting including in it wordpress. Go to wordpress.com and start blogging. The others are weebly, google blogspot etc... but they do not have wordpress. They have their own themes.
online.biz It gives you a list of different platforms you can use, including Wordpress. Yup, it's free.
Decent web hosting does not cost alot, but it gives you security and control... You can't put a price on security and control if you really care about your site.
I used byethost as free hosting service long ago. Uptime is good and there's an easy control panel to install and manage the scripts.
