Let's divide 863129 by 11
Our goal is to divide 863129 by 11.

Advancing to step 1:
If we divide 8 by 11, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 11

Moving on to step 2:
11 can be fit into 86 7 times, resulting in a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 77 from 86 leaves us with 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 11

Advancing to step 3:
The number 11 fits into 93 8 times, leaving a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
Subtracting 88 from 93 leaves us with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 11

Step 4:
The number 11 fits into 51 4 times, leaving a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 784.0
The remainder is 7 after subtracting 44 from 51.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 11

Moving on to step 5:
The number 11 fits into 72 6 times, leaving a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 7846.0
If we subtract 66 from 72, we get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 11

Step 6:
The number 11 fits into 69 6 times, leaving a remainder of 3.
The next digit of our result is 6. 
Result so far: 78466.0
The remainder is 3 after subtracting 66 from 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
30 divided by 11 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 78466.2
If we take 22 away from 30, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
11 can be fit into 80 7 times, resulting in a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 78466.27
Subtract 77 from 80 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
30 divided by 11 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 78466.272
Deduct 22 from 30 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
The number 11 fits into 80 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 78466.2727
If we take 77 away from 80, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
If we divide 30 by 11, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 78466.27272
If we subtract 22 from 30, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
80 divided by 11 is 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 78466.272727
If we take 77 away from 80, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
If we divide 30 by 11, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 78466.2727272
Subtracting 22 from 30 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 14:
11 can be fit into 80 7 times, resulting in a remainder of 3.
The next digit of our result is 7. 
Result so far: 78466.27272727
Subtracting 77 from 80 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final outcome is 78466.27272727, with a leftover of 3e-09.
