Now that you downloaded and extracted the WordPress CMS?, you would now want to upload WordPress to your website. Open your FTP client, and log into your server. Navigate to the folder on the server for your website. Open that folder, and upload the WordPress CMS to the folder. This will take some time depending on the speed of your internet plan. My upload on a 10MBPS upload can take 5-10 minutes depending on the day. Expect everything to upload with some time.
