What is the division of the cytoplasm

Cytokinesis.

Explanation:

The division of a cell's cytoplasm is known as cytokinesis. Cytokinesis is the last stage of the mitosis cell division process. A mitosis is a form of asexual cellular division. Mitosis has four steps:

Prophase: Prophase is the first phase or step of the mitosis. In this stage, where a parent cell separates into the two identical daughter cells which carry the genetical materials of the parents.

Metaphase: In this stage, the microtubules of the spindle become connected. Along with this, the chromosomes have lined up on the metaphase plate.

Anaphase: in this stage, the sister chromatids are pulled aside and move toward the opposite poles of the cell.

Telophase: Telophase is technically the final stage of mitosis. During this phase, the sister chromatids reach the opposite poles of the cell. Along with this, the small nuclear vesicles in the cell starts re-forming around the group of chromosomes at each end. After this stage, again, the prophase stage starts.
