139321 ÷ 11 
Our goal is to divide 139321 by 11.

On to step 1:
11 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 11

On to step 2:
11 goes into 13 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 11 from 13 leaves us with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 11

Step 3:
11 goes into 29 2 times with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 22 from 29 and we're left with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 11

Going ahead to step 4:
If we divide 73 by 11, we get 6 and a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
Deduct 66 from 73 and we're left with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 11

Step 5:
11 can be fit into 72 6 times, resulting in a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 1266.0
If we subtract 66 from 72, we get 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 11

Step 6:
11 can be fit into 61 5 times, resulting in a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 12665.0
Subtract 55 from 61 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
The number 11 fits into 60 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 12665.5
Subtract 55 from 60 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
When dividing 50 by 11, we get 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 12665.54
If we subtract 44 from 50, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
If we divide 60 by 11, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 12665.545
If we subtract 55 from 60, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
11 can be fit into 50 4 times, resulting in a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 12665.5454
The remainder is 6 after subtracting 44 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 11:
If we divide 60 by 11, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 12665.54545
Subtracting 55 from 60 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.

Step 12:
11 can be fit into 50 4 times, resulting in a remainder of 6.
The next digit of our result is 4. 
Result so far: 12665.545454
Subtract 44 from 50 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
The number 11 fits into 60 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 12665.5454545
Deduct 55 from 60 and we're left 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.

Let's proceed to step 14:
The number 11 fits into 50 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 12665.54545454
If we subtract 44 from 50, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 12665.54545454 with a balance of 6e-09.
