The major division in Saturn's rings is called the Cassini Division. It is a large region that separates Saturn's rings into two main sections.
I don't think there are any animals in the archaebacteria division. They are unicellular microorganisms that can survive in harsh environments. Three types are halophiles, methanogens, and thermophiles.
The two major divisions of mitotic cell division are the first stage, known as karyokinesis, where the nucleus divides, and the second stage, cytokinesis, where the cytoplasm splits to form two daughter cells.

The major division of the internal are cochlea and ear drum and Eustachian tube
If by animal you mean 'anything that respirates(oxygen)' then the two major subdivisions would be protozoic and metazoic. That is single celled and multi-celled. If by animal you mean 'Metazoic repirators(oxygen)' then the two major subdivisions would be protoastomes and dueterostomes. That is single opening to digestive tract and two openings to digestive tract. (With sponges forming a third branch that we will ignore for the sake of the two division criteria.)
