trying to study for a test, but i don't know the steps to solving this question

I think it means divides evenly (?)  

     Just sub in 0    to see

                   39245930/8 = 4905741.25     the .25 tells us that 6 more is needed to divide evenly

 

                    39245936/8 = 4905742      Tht will be the only value......adding 8 more would change the digit in the tens place
