What are the key events?

Prophase: the nucleus dissolves, chromatin are condensed into chromosomes, centrioles begin moving to opposite sides of the cell and fibers extend from the centromeres

Metaphase: spindle fibers align chromosomes in the middle of the cell referred to as the metaphase plate. This helps to ensure that each new daughter cell will receive on copy of each chromosome.
Anaphase: the chromosomes are pulled apart by centrioles
Telephase: chromatids arrive at opposite ends of the cell and new membranes are formed around the daughter nuclei
Cytokenisis: the cytoplasm divides and two new daughter cells are formed
