Dividing exponent with same base

Question

There are $~2^{80}~$ possibilities to calculate and I want to divide it by $~2~$ to process it by two computers at the same time to find the answer maybe sooner.

How can I divide $~2^{80}~$ by $~2~$?

Answer 1

$$\frac {2^{80}}2=\frac{2^{80}}{2^1}=2^{80-1}=2^{79}$$ Having two computers does not make much of a dent.
