Several things must happen, but the most important is that the DNA must be copied or replicated.

The mitotic phase is a relatively short period of the cell cycle. It alternates with the much longer interphase, where the cell prepares itself for cell division. Interphase is divided into three phases, G1 (first gap), S (synthesis), and G2 (second gap). During all three phases, the cell grows by producing proteins and cytoplasmic organelles. However, chromosomes are replicated only during the S phase. Thus, a cell grows (G1), continues to grow as it duplicates its chromosomes (S), grows more and prepares for mitosis (G2), and divides (M).

Duplication or replication of the dna must take place.
Also, they must arrange themselves in the form of chromosomes.

chromosomes double, staying attached at the centromere :)
