Merge smaller polygons that are within a larger polygon

I am trying to find the best way to merge small polygons into one polygon. They have to be merged to match provincial subdivisions. What I'm working on you can see below:

So I have to merge the little aquamarine polygons into one for each subdivision, delineated by the grey lines. There are roughly 3260 aquamarine polygons, and 153 subdivision polygons. In the end I would need 153 (or less since some subdivisions do not contain aquamarine polygons) aquamarine polygons.


Any thoughts on how?
