When something large or complex is split into smaller parts, you can call each part a subdivision. The act of separating something into parts is also called subdivision.

In North America, when someone mentions a subdivision, they probably mean a suburban neighborhood. When planned communities are designed, developers subdivide the plots of land to make it easier to sell them. If a botanist talks about subdivisions, she means something completely different: a ranked group of plants. No matter how the word is used, a subdivision is basically a smaller section of a section, or a part of something that's divided.
