Best online free Spanish to English dictionary?

The only trouble I am having is it doesn't always have the literal translation for the words in the sentences in the Spanish lessons for instance what does 'le va 'mean in English in the sentence 'como le va' - 'how are you getting along'?. When I looked le and va up in the first dictionary I came across I just got more confused. Can anyone recommend the best online dictionary? Thanks for your help.
