Ranking portions of data with the same number

I have 4,300 cells populated with data. I have sorted the data and now I need to rank the data in 1% increments. For example, the first 1% of data (43 cells) will be ranked #1, the second 1% of data (43 cells) will be ranked #2 etc. How could I automate this process? I was trying to figure something out with the "Rank" command but that doesn't seem to work in this situation. Thank you.

Thank you so much. This is exactly what I needed and I cant believe how much time I wasted trying to figure it out. One thing for certain -- I would never have gotten there without your help. I was on the verge of starting to do it manually. Thank you again!!!!!
