Website getting indexed in "parts" by google.

Hi! I am currently using this theme for a luxury website and I recently noticed that Google indexes my site using “parts” as in individual numbered pages. For example, I get Part 1 to Part 20 indexed in Google search, which are actually the different numbered pages of my website. I fear this might create a duplicate content issue as the numbered pages include small snippets of text from the original articles. I am trying to run a tidy, post-only indexed website and I don’t really know where to put the robots noindex tag in this particular scenario. Any help would be greatly appreciated.
