We can write two division problems related the given equation as follows.
Division problem one :
Here 8 is in multiplication with -2 on the left side.
so when we bring this 8 on the right side, we will have to apply opposite operation of multiplication which is division.
so dividing (-16) by 8 on the right side, we have:

Division problem two :
Here -2 is in multiplication with 8 on the left side.
so when we bring this (-2) on the right side, we will have to apply opposite operation of multiplication which is division.
so dividing (-16) by (-2) on the right side, we have:
