To solve this equation, we need to follow the order of operations, which is parentheses, exponents, multiplication/division (from left to right), and finally addition/subtraction (from left to right).

In this case, we need to divide 100 by (-10) first, then divide the result by 5.

100 divided by (-10) equals -10.

Then, dividing -10 by 5 gives us -2.

Therefore, 100 divided by (-10) divided by 5 equals -2.
