Here's one (somewhat non-standard) way:

0-400:
=SUM((COUNTIF(A1:A10,{"=0","400"})*{1,-1}))

401-800:
=SUM((COUNTIF(A1:A10,{"=401","800"})*{1,-1}))



Is that something you can work with?

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...
