Interesting question!
I'll try and keep my answer short and concise (for once!)

'Very rapid':
1. Early embryonic cells (if you didn't know, the cell cycle consists of phases: G1, S, G2 and M - with these cells they essentially 'skip' through G1 and G2 (i.e. no cell growth) and instead just rapidly divide to produce more cells)
2. Cancer cells
3. Stem cells (epidermal stem cells (for the skin); hematopoietic stem cells (for the blood))

'Relatively slow'
1. Liver cells
2. Kidney cells

Does not divide:
1. Almost every other specialised cell in the body - cells, once specialised, normally do not divide, but instead are 'replaced' if they are damaged (nerves (in central nervous system), heart muscle)

Hope this has helped at least a tiny bit!
