Here you go,

Mitosis occurs in two stages
1.Karyokinesis
2.Cytokinesis

● Karyokinesis is further divided into four phases
1.Prophase
here,
◆centrioles move apart
◆chromosomes become distinct
◆sister chromatids attached to each other at centromere
◆spindal fibres appear between centrioles
◆nuclear membrane and nucleolus disappears

2.Metaphase
here
◆chromosomes get attached to the spindal fibres at centromere
◆chromosomes line up in equator

3.Anaphase
here,
◆centromere attaching the two chromatids divide
◆furrow start in the cell membrane

4.Telophase
here,
◆Daughter chromosomes reach opposite poles
◆spindal fibres disappears
◆chromatin fibres are formed
◆nuclear membrane and nucleoli reappear

●In Cytokinesis two daughter cells separate and new cells are formed.
