Modulus in Applesoft

Hi,
I'm having problems using the Modulus operator under Applesoft, or don't
know how to do it.  In Integer, if I remember correctly, you could do, E.G.
10 poke 493,x mod 256:poke 494,x/256
and have a memory address poked in.  That's just an example.  However, doing
print 900 mod 256
in Applesoft produces the result 9000, and I think I just figured out why.
I think it's printing the number 900, then the contents of variable 'mod'
which is 0.  So how do you do that in Applesoft?
Thanks.
