We look at the division of 129755 by 9 
We're looking to find how many times 9 goes into 129755.

Step 1:
1 divided by 9 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 9

Step 2:
When dividing 12 by 9, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 3 after subtracting 9 from 12.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 9

Advancing to step 3:
If we divide 39 by 9, we get 4 and a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 3 after subtracting 36 from 39.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 9

Going ahead to step 4:
37 divided by 9 is 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 144.0
The remainder is 1 after subtracting 36 from 37.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 9

Moving on to step 5:
15 divided by 9 is 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1441.0
If we take 9 away from 15, we end up with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 9

Advancing to step 6:
The number 9 fits into 65 7 times, leaving a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 14417.0
Deduct 63 from 65 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
9 can be fit into 20 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 14417.2
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
The number 9 fits into 20 2 times, leaving a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 14417.22
Subtracting 18 from 20 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 14417.22, and the remainder is 0.002.
