I get a lot of people asking how to do this and thought I may as well put up a video. I cover not only slowing down and freezing a simulation but also freeze framing a render and using offsets to render multiple containers from a single simulations data. This is part of my 13 hour tutorials set the link is in the video description

Oh…the negative frame steps allow you to play the sim backwards during render… You can of course keyframe and animate those settings.
