4.55 * 10^-1
-------------------
6.55 * 10 ^-4
The first step is to divide the numbers
4.55 / 6.55 = .694656489
Then divide the exponents
When dividing exponents, use the quotient rule
10 ^-1 / 10 ^-4 = 10 ^(-1 - -4) = 10 ^ (-1+4) = 10 ^3
.694656489 * 10 ^3
But we need the answer in scientific notation, which means one number before the decimal
shifting one place to the left and subtract 1 from the exponent
6.94656489 * 10 ^2
