The idea is to use to modulo operator % which gives you the residue of a 
number when divided by another number:

x = 0
while x < 2000:
     x += 1
     if x % 100 == 0:
          do_something()


Note that it is probably more appropriate to use a for loop:

for x in range(2000):
     if x % 100 == 0:
         do_something()
