=COUNTIF(B1:B8,"<=400") (assuming all numbers are positive)

=COUNTIF(B1:B8,"=401")-COUNTIF(B1:B8,"800")

My worksheet is like this:
A1 A2...
120 210 333 400 510 625 789 801 ...10000

How can I get the how many of the cells the cells have a value between 0 and
400 (in the question above 4), how many times the cells have a value between
401 and 800 (3), etc.?

Thanks in advance...
