We're dividing 13939 by 99 
We want to divide 13939 by 99.

Step 1:
99 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 99

Going ahead to step 2:
99 goes into 13 0 times with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 99

Advancing to step 3:
99 goes into 139 1 times with a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 99 from 139 leaves us with 40.
Bring next digit (3) of the dividend behind the 40 and repeat the process: 403 / 99

Moving on to step 4:
403 divided by 99 is 4 with a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 7 after subtracting 396 from 403.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 99

Step 5:
99 goes into 79 0 times with a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 140.0
Subtracting 0 from 79 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 6:
When dividing 790 by 99, we get 7 with a remainder of 97.
Put 7 as the next digit of the answer. 
Result so far: 140.7
The remainder is 97 after subtracting 693 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 7:
99 can be fit into 970 9 times, resulting in a remainder of 79.
The number 9 becomes the next digit in our result. 
Result so far: 140.79
Subtract 891 from 970 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 8:
When dividing 790 by 99, we get 7 with a remainder of 97.
Use 7 as the next digit of our solution. 
Result so far: 140.797
The remainder is 97 after subtracting 693 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Going ahead to step 9:
If we divide 970 by 99, we get 9 and a remainder of 79.
Record the quotient 9 as the next digit in the result. 
Result so far: 140.7979
Deduct 891 from 970 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 10:
790 divided by 99 is 7 with a remainder of 97.
The next digit of our result is 7. 
Result so far: 140.79797
Subtract 693 from 790 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Advancing to step 11:
The number 99 fits into 970 9 times, leaving a remainder of 79.
Use 9 as the next digit of our solution. 
Result so far: 140.797979
If we subtract 891 from 970, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 12:
99 can be fit into 790 7 times, resulting in a remainder of 97.
Write down 7 as next digit of the result. 
Result so far: 140.7979797
If we subtract 693 from 790, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Let's proceed to step 13:
99 goes into 970 9 times with a remainder of 79.
The next digit of our result is 9. 
Result so far: 140.79797979
If we take 891 away from 970, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

In conclusion, the division gives 140.79797979 with a balance of 7.9e-08.
