Use scientific notation to divide the following two numbers. Express the answer using scientific notation; retain at least three decimal places. 6.2 • 107 / 4.15 • 103

Retain three decimal places....Goodness,then the numerator should have been written 6.20E7, with three significant digits.
So what is 6.20/4.15 E4 ?
