I need help with this question for my homework assignment.

3.31 Calculate by hand 8.625 x 10^1 divided by -4.875 x 10^0. Show all the steps necessary to achieve your answer. Assume there is a guard, a round bit, and a sticky bit, and use them if necessary. Write the final answer in both the 16-bit floating point format described in Exercise 3.27 and in decimal and compare the decimal result to that which you get if you use a calculator.
