Make sure you have the most recent version of WordPress. Download Area on WordPress.org
Once the zip file is downloaded to your local computer, then unzip the files
Upload the folders inside the /wordpress folder on your computer (from the inflated zip file) to your public html web directory on your web host.
Inside your hosting control panel, create a new MySQL database for the WordPress Installation
When the files have finished the FTP process and your database exists, navigate to yourdomain.com/wp-admin/ to generate your initial configuration file. Make sure to save the admin password that is auto generated by wordpress.

A few tips:
You may wish to create a blank file named .htaccess and also upload this to your public html directory, then CHMOD it 777. This will allow you to easily turn on permalinks.
I recommend using the custom permalink structure of: /%postname%/ . This will help keep your urls short, position keywords closer to your root domain level, and make navigation more user friendly.
