°° Awesome question!
I'll show you how to solve this kind of question:
First, you can multiply 9 times any number to see if it's smaller than 67. If it is, it is OK to keep multiplying 9 by more numbers. Let's try this!
9 × 1 obviously equals 9, so we can keep going up.
9 × 2 = 18. Not quite there yet!
Sometimes it is OK for you to skip some numbers, Watch:
9 × 5 = 45. We can keep going. At this point you don't need to go backwards and do 9 × 3 or 9 × 4, because the products will only get farther away from 67.
9 × 6 = 54. We're getting closer!
Let's try to skip one number:
9 × 8 = 72 - HOLD UP! Oh no! We went over a little too much!
Let's try a number in between 6 and 8 - That would be 7, right?
9 × 7 = 63 - We were right on point! Obviously you can't multiply 9 by 8 again because you would get a bigger number - the 72.

That was just one way to go about it, but there's another way, too!
You can divide 9 by 67 and see what you get. You may have a remainder, but you can just throw that out the window when we're all done:
9 ÷ 67 = 7.4444444444444444 The 4 just repeats on and on again, and we don't want that. So just throw those 4's out the window so you're left with 7.
Based on all this work, 9 goes into 67 7 times.
