I'm getting a bit confused by some of the other answers on here. Not sure if you mean how to show a reoccurring habit that a character has without repeating it or the actual repeating of time and space ie. Rashomon, Groundhog Day, Back to the Future, Vantage Point, Snake Eyes, Edge of Tomorrow etc. However, my answer is for the latter.
One of the most basic things you constantly want to keep in mind no matter what kind of story you're telling is perspective (perspective of story, perspective of character, etc). You know the saying "There's always two sides to every story"? The reason why that is is because of perspective. In these movies with elements of repetition, perspective becomes even more important.
In movies like, Groundhog Day, Edge of Tomorrow, there's an INTERNAL shift in perspective going on. What does the character learn everytime the loop comes back around and how does that change their perspective. What did Billy Murray/Tom Cruise's character learn and how does their perspective change this next time around?
In movies like Rashomon, Vantage Point, and Snake Eyes, the perspective shift is EXTERNAL. We see the the same exact story unfold repeatedly but the story evolves because each new instance is through the eyes of a different character.
In both cases, the events repeat but the story evolves simply because of the shift of perspective. Two sides to every story.
Keep in mind the PERSPECTIVE at all times and everything will fall into place from there. You'll realize what elements of the story you should show now vs. what you should show later. What you should repeat vs. what you don't need to repeat. You'll realize what angles and shots are more effective because of the perspective at which the story is being told at that moment. Keeping perspective in mind will effect everything from the writing process, to shooting, to even how you edit it.
As another example, here's a link to a short that I wrote and directed last year that actually has this repeating element. It was selected top 12 by NBCUniversal Short Cuts Film Festival in 2013 (along with NFS' own Ryan Koo's short film Amateur) and went on to screen in London, LA, and New York.
As you could see it could've easily become confusing and there are moments that are repeated, however, it all serves a purpose and everything is based on the perspective.
Hope this helps. Happy filmmaking! =)
