I need an explanation

I'm starting to actually like math.  Now that I'm seeing the relationships and patterns that permeate the subject, it all makes a lot more sense.  I came across this neat number trick, and I want to know how it works.

Multiply 37,037 by any single digit, multiply by 3, and the answer is a string of digits that is the same as the first single digit multiplied by at the beginning.

Try it.  It works.  But I don't know why, and I'm insanely curious.  Anybody want to take a stab at explaining to me why it works?
