How to learn arabic online free?

I am interested to learn Arabic including holy Quran through internet, online. I am interested to learn the language in such a way that I should be able to speak Arabic and at the same time I should be able to understand the meaning of the article or book which are written on Arabic. Is it possible to learn Arabic up to that much level in the commuter online without any investment. Is there any website or blog providing that facility on the language of the holy Quran step by step. Please if any body has some good resources or information on my question matter, You please just fun mail me.

If you have a google page, you can add an arabic translator to your page, of an Arabic- English dictionary.

Buy an english Quran(with the meaning ön every page) and an english arabic dictionary!
See how Easy it is? Lol
