Let's divide 122131 by 9
We want to figure out the number of times 122131 can be divided by 9.

Step 1:
The number 9 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 9

Going ahead to step 2:
When dividing 12 by 9, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 9 from 12 leaves us with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 9

On to step 3:
The number 9 fits into 32 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 27 from 32 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 9

Advancing to step 4:
If we divide 51 by 9, we get 5 and a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 135.0
If we subtract 45 from 51, we get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 9

On to step 5:
The number 9 fits into 63 7 times, leaving a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 1357.0
Deduct 63 from 63 and we're left with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 9

Going ahead to step 6:
9 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 13570.0
The remainder is 1 after subtracting 0 from 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
10 divided by 9 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 13570.1
If we subtract 9 from 10, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
10 divided by 9 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 13570.11
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 13570.11, and the remainder is 0.001.
