I find that when I'm trying to understand what's going on, the best way to
figure it out is to use IRB

E:\Documents and Settings\Jason>irb
irb(main):001:0> input = 3123
=> 3123
irb(main):002:0> m_mod = input%1000
=> 123
irb(main):003:0> m_div = input/1000
=> 3
irb(main):004:0> m = 'M' * m_div
=> "MMM"
irb(main):006:0> puts m
MMM
=> nil
irb(main):007:0>

You can probably figure out the rest from there.   Hope that helps.
