We look at the division of 831221 by 11 
Our goal is to divide 831221 by 11.

Advancing to step 1:
If we divide 8 by 11, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 11

Going ahead to step 2:
11 can be fit into 83 7 times, resulting in a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 77 from 83 and we're left with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 11

Let's proceed to step 3:
11 can be fit into 61 5 times, resulting in a remainder of 6.
The next digit of our result is 5. 
Result so far: 75.0
Subtracting 55 from 61 leaves us with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 11

Let's proceed to step 4:
When dividing 62 by 11, we get 5 with a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 755.0
Subtracting 55 from 62 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 11

Step 5:
The number 11 fits into 72 6 times, leaving a remainder of 6.
The next digit of our result is 6. 
Result so far: 7556.0
Subtracting 66 from 72 leaves us with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 11

Step 6:
When dividing 61 by 11, we get 5 with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 75565.0
The remainder is 6 after subtracting 55 from 61.
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 7:
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: 75565.5
The remainder is 5 after subtracting 55 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
11 can be fit into 50 4 times, resulting in a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 75565.54
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.

On to step 9:
The number 11 fits into 60 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 75565.545
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.

Let's proceed to step 10:
The number 11 fits into 50 4 times, leaving a remainder of 6.
The next digit of our result is 4. 
Result so far: 75565.5454
Deduct 44 from 50 and we're left with 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 11:
11 goes into 60 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 75565.54545
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.

Advancing to step 12:
11 goes into 50 4 times with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 75565.545454
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.

On to step 13:
60 divided by 11 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 75565.5454545
If we take 55 away from 60, we end up 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.

Moving on to step 14:
If we divide 50 by 11, we get 4 and a remainder of 6.
The next digit of our result is 4. 
Result so far: 75565.54545454
If we take 44 away from 50, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 75565.54545454 with a remaining 6e-09.
