divisibility homework question I'm stuck on this problem for my math homework and could really use some help.

Definition A: Let $a$ and $b$ be integers. We say that $a$ is divisible by $b$ provided there is an integer $c$ such that $bc = a$.
Definition B: Let $a$ and $b$ be integers. We say that $a$ is divisible by $b$ provided $a/b$ is an integer.

The question asks to find integers $a$ and $b$ that are divisible according to one definition, but are not divisible according to the other.
Any guidance would be really appreciated.

Thanks to @aduh, I have solved the question: 
Let $a=  b=0$. In Definition A, $a$ is divisibile by $b$ since $0c = 0$, where $c=0$. In definition B, $a/b = 0/0$ is undefined.
