Excel 2007 : Command to bin a range on numbers

[samd1977]

Hi,
I am curious to know if there is a command(s) in Excel which can be used to divide the numbers in a sorted list into equal bins?
For example if I have a list of 100 numbers I would like to divide them into 5 groups of 20 numbers each starting with the smallest 20 in the first bin and proceeding to the largest 20 in the last bin.
Thanks for your help!

Like 100 numbers in col A into 5 groups of 20 in cols B, C, D, E, & F?
