Let's review what you've learned about short division with a zero in the quotient, or answer. You know that when the digit under the division sign is less than the divisor, you underline two digits under the division sign. Then you can divide the numbers. When you have to use a two-digit number to divide after that, you'll have a zero in the quotient.
Take a look at this problem:
We can't divide 1 by 9, so we underline 18.
We work 18 divided by 9, which equals 2 (18 ÷ 9 = 2). We write 2 above the 8 in the hundreds place.
We can't divide 5 by 9, so we underline 54.
To show that we tried to solve 5 divided by 9, we write a zero above the 5 in the tens place.
Then we work on 54 divided by 9, which equals 6 (54 ÷ 9 = 6). It's that easy!
