<pre>

1.4 × 10<sup>-4</sup>
——————————
  7 × 10<sup>-7</sup>

Move the 10<sup>-7</sup> from bottom to the top and
change the sign of the exponent of 10 from -7 to 7

1.4 × 10<sup>-4</sup> × 10<sup>7</sup>
————————————————
  7 

Combine the exponents -4+7 as 3

1.4 × 10<sup>3</sup>
—————————
  7 

Put some 0's after the 1.4 so we can the move the decimal 3 places right:

1.400 × 10<sup>3</sup>
———————————
  7 

Move the decimal 3 places right and remove the "× 10<sup>3</sup>"

1400
