You may be thinking like Lili did.

In some contexts, dividing is repeated subtraction. For example if we begin with 12 and repeatedly subtract groups of 4, we can do that three times. So 12 divided by 4 is 3. 

But in this case, we are repeatedly subtracting from zero. The result is a rectangle, which is what we get from multiplying. 

So, what multiplication is represented by the rectangle that results when groups of five yellow tiles  are removed three times? 

☐ 5 • 3  

☐ 5 • 3
