What do cells need to do between divisions to make sure that a full set of DNA gets passed on each daughter cell

They need to replicate the full amount of their DNA so that there are two complete copies for each daughter cell to get one.

The "cell cycle" consists of a resting phase or G0 phase followed by Interphase, which is divided into G1, S and G2 phases. The G1 phase prepares the cell to replicate its DNA, the replication of the DNA then takes place in the S phase, and then during the G2 phase the cell prepares to enter the M phase which is when the actual mitosis or cell division happens.
