Answer by Earlsdon(6294) (Show Source): You can put this solution on YOUR website!
You should include the zero for completeness, and notice that you start at an exponent of 9:
1,203,487,386 =
1,000,000,000 =
200,000,000 =
-------------------------
3,000,000 =
400,000 =
80,000 =
7,000 =
300 =
80 =
6 = Recall that
