7.18*10^(-12)
There is a good and handy way to solve this if you don't have a calculator on hand that can handle scientific notation like this.
First step is to make everything into scientific notation:
.001232 = 1.232*10^(-3)
You can then work with both of the regular numbers first by using a simple calculator or doing the division by hand:
8.84/1.232 = 7.18
You can then work with the powers of ten by themselves. Remember, when you divide exponents with the same base (in this case the base is "10"), you can just subtract the exponents.
[10^(-15)]/[10^(-3)] = 10^(-12)
Then put them together and voila!
7.18*10^(-12)

10^(-15) is equal to 10/100000000000000 thus 8.84*10^(-15) is 8.84 multiplied by the above . and then this answer could be again divided by .001232 to get the final answer. 10^(-15) could be typed the same way on a scientific calculator
