Let's divide 864120 by 11
We want to figure out the number of times 864120 can be divided by 11.

Advancing to step 1:
The number 11 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 11

On to step 2:
11 goes into 86 7 times with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 77 from 86 leaves us with 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 11

Going ahead to step 3:
If we divide 94 by 11, we get 8 and a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 78.0
If we take 88 away from 94, we end up with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 11

Step 4:
61 divided by 11 is 5 with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 785.0
If we subtract 55 from 61, we get 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 11

Going ahead to step 5:
When dividing 62 by 11, we get 5 with a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 7855.0
If we subtract 55 from 62, we get 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 11

On to step 6:
11 can be fit into 70 6 times, resulting in a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 78556.0
If we subtract 66 from 70, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
The number 11 fits into 40 3 times, leaving a remainder of 7.
The next digit of our result is 3. 
Result so far: 78556.3
Subtracting 33 from 40 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 8:
When dividing 70 by 11, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 78556.36
Deduct 66 from 70 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
11 can be fit into 40 3 times, resulting in a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 78556.363
Subtract 33 from 40 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 10:
If we divide 70 by 11, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 78556.3636
The remainder is 4 after subtracting 66 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
40 divided by 11 is 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 78556.36363
The remainder is 7 after subtracting 33 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 12:
If we divide 70 by 11, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 78556.363636
If we subtract 66 from 70, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
The number 11 fits into 40 3 times, leaving a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 78556.3636363
If we take 33 away from 40, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 14:
70 divided by 11 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 78556.36363636
Deduct 66 from 70 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 78556.36363636, and the remainder is 4e-09.
