120252 ÷ 9 
We're looking to find how many times 9 goes into 120252.

Step 1:
The number 9 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 9

Let's proceed to step 2:
When dividing 12 by 9, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 9 away from 12, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 9

On to step 3:
9 can be fit into 30 3 times, resulting in a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 27 from 30 leaves us with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 9

Step 4:
32 divided by 9 is 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 133.0
Subtracting 27 from 32 leaves us with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 9

Let's proceed to step 5:
The number 9 fits into 55 6 times, leaving a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 1336.0
The remainder is 1 after subtracting 54 from 55.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 9

Going ahead to step 6:
When dividing 12 by 9, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 13361.0
If we take 9 away from 12, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
30 divided by 9 is 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 13361.3
Subtract 27 from 30 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 8:
If we divide 30 by 9, we get 3 and a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 13361.33
Subtract 27 from 30 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 13361.33 and a remainder of 0.003.
