They don't always divide, in multicellular organisms they typically just stop growing, in slime molds the cells can get more than a foot in diameter without dividing (they have tens of thousands of nuclei per cell).
They copy their chromosomes so that when they do divide into two different cells each one will have its own set of chromosomes and it couldn't be copied and transferred after divison occured
Cells divide as the zygote becomes a fetus with growth and development into babies when born, cells also divide with growth after birth into adulthood and to replenish and renew damaged or lost cells.
cell division is how organisms grow.
Cells in the body do not need to carry out every function independently. They depend on other cells and systems to support their activities. Additionally, not all cells in the body need to divide constantly, with some cells being quiescent or terminally differentiated.
Replication of DNA
Cells are in endocytosis when they are not dividing, this is just maintaing life and growth to divide again.

In order to replace the cells that are dieing
Cells need to get rid of large particles they don't need
Liver cells divide about once a year, and neurons (nerve cells) never divide once we are born (and when they are mature).

Because body cells need to make genetically identical daughter cells and sex cells need to make genetically unique cells with half the genetic material of the parent cell.

The overall area of it's membrane will not be large enough to take in sufficient nutrients for it's size, and therefore the cell will either need to divide, or it will die.
