Subject: Re: how do deal with huge numbers and keep them accurate?

thanks u all for taking a few minutes to answer me. I'm really 
embarrassed cause I wanted to simplify the question so, I didn't wrote 
down the actual code. I also sorry for not posting any answer yesterday. 
so once more, your help would be very much appreciate...

(I'll drop the 3 lines at the beginning cause I don't sure about them, 
and don't want to mislead you. (talking about: include... require... 
etc).

this is what i want to achieve with that code:

number = gets.chomp.to_f
divider = 3.0
while number % divider != 0
divider += 1.0
end
puts divider.to_s
if divider == 3.0
 puts "the number can be divided by " + divider.to_s
else
 puts "can't be divided"
end

that's it. sorry for repeating myself... once more:
i want the ability to input a number like this: 
333333333333333333333333333333331
we all know that the answer will be something like that: 
1111.....111.333333
but the code will give me the answer that it can be divide by 3, and 
that's the main problem in that code.

Thanks in advanced, Tomiz.
p.s. i have tried to implement all of your suggestions with no luck. 
I've add the code for your comfort.
