Sexual Reproduction: During the developmental stage, the zygote performs rapid cell division and all through pregnancy, these cells continue to divide and create the baby that is created.
Asexual Reproduction: The organism that is going through cell division creates two new daughter cells/organisms which increases the population.
Repair and Maintenance: When cells die off in multicellular organisms, other cells go through cell division in order to fill the gap that has been created. This happens whether the first cell dies from old age, poison, damage, lysis, or invasion.
There are some others, but these are the main ones that I can think of right now.
Living Organisms grow from cell division and growth hormones
Single cell organisms.
Cell division is how a single-celled organism reproduces.
1. Development from a fertilised cell ie Reproduction 2. Growth 3. Repair and replacement of worn out tissue
For multicellular organisms (like us) cell division allows an organism to grow and develop from a single cell to trillions of cells, to repair and replace cells worn out and used up by everyday life, and in some cases, to make specialized cells for reproduction. or, to make it more easy to understand, in multicellular living things, cell division is required for tissue repair and growth. :)

plays role in cell division.
plays role in cell division.
Without cell division cells and DNA cannot replicate, therefore organisms would all be unicellular. Without cell division human skin, bone, muscle and stem cells wouldn't replicate either therefore making the human existence impossible. That doesn't just apply to humas though, any multi-cellular organism you know of would not exist.
Cancer happens if the cells divide too fast.
If not for cell division, we would all have to be unicellular organisms. There would be no multicellularity, and that wouldn't get much done now would it?
Single cell organisms.
Who cares?? Seriously!! Stupid Science
Regeneration is the process that uses cell division to re-grow body parts.
Bacteria are prokaryotic organisms that reproduce by cell division.
Cell division takes place in single-celled organisms to reproduce and pass on genetic information.
