Step by Step?
Sorry, this is very easy!
I haven't magento from the bitnami stack - i've used xampp and magento 1.9.x.
But it's the same procedure.
Go in your local database and make a backup.
Go to your server database and import it.
Connect with a ftp-client to your server and move the magento folder(s) and files to the server.
After that you have to change the config from your local-data for the server-data (in magento 1.9.x it was the file config.xml in /app/etc/).
I'm sure you can use google to find a backup guide too.
