How would I divide the following integers
(-120)(31)/(-5)(-8)(9)
My result is -3720/360 but my book tell me it is zero?

The expression is somewhat ambiguous. It be read either as
$\frac{(-120)(31)}{(-5)(-8)(9)}$
or as
$\frac{(-120)(31)(-8)(9)}{-5}$
When writing expressions like this, you should always place brackets to make the grouping of terms obvious.
In any case, the answer is certainly negative, since none of the factors in the numerator are zero, and there are three minus signs.
In the first case, the fraction simplifies to
$-\frac{3720}{360} = -\frac{31}{3}$
which is presumably how you arrived at your answer, and in the second case it simplifies to
$-53568$
