As the title explains, I have one container div, containing two floating divs of varying widths. See it in action here (it's the "Hotel booking" part):

I bordered the 2nd div for you. I need this 2nd div to fill out all the remaining space of the container div. I cannot fix the width of the first div, since the width of it varies depending on what the different hotels offer, but I still want the 2nd div (where the prices will appear) to fill out all the remaining space, to not make it so cramped.
How is this result achieved?
