When x is 0 for the equation y=10/x, y is obviously 0. How can i explain why this happens in words? and i know that division is finding how many times one number is contained in another. Is it 10 goes into 0, 0 times or 0 goes into 10, 10 times?

That's what I wrote. But my teacher circled it, meaning it's wrong. :(
