We're dividing 129735 by 10 
We're looking to find how many times 10 goes into 129735.

On to step 1:
10 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 10

Moving on to step 2:
The number 10 fits into 12 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 10 from 12 leaves us with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 10

Moving on to step 3:
The number 10 fits into 29 2 times, leaving a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 20 from 29 to get 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 10

On to step 4:
97 divided by 10 is 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 129.0
If we subtract 90 from 97, we get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 10

Step 5:
10 goes into 73 7 times with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 1297.0
Deduct 70 from 73 and we're left with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 10

Moving on to step 6:
If we divide 35 by 10, we get 3 and a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 12973.0
Subtracting 30 from 35 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
The number 10 fits into 50 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 12973.5
If we subtract 50 from 50, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
10 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12973.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
When dividing 0 by 10, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 12973.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 12973.5 with a remaining 0.0.
