Literally it means we are not moving. But we would use it to say however hard we try something is not working therefore we are not getting anywhere. So however much work you put into something if you are not finding an answer 'this is not getting us anywhere'

above is correct but the clause can also be used metaphorically. The phrase is used in many conversations and arguments that have no conclusion.

This isn't getting us anywhere. If a bus doesn't move it won't get you anywhere. Now use that image to understand the phrase.
