868721 divided by 11 
The aim is to understand the frequency of 11 in 868721.

Step 1:
11 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 11

Let's proceed to step 2:
The number 11 fits into 86 7 times, leaving a remainder of 9.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 77 from 86 leaves us with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 11

Moving on to step 3:
11 can be fit into 98 8 times, resulting in a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 78.0
Deduct 88 from 98 and we're left with 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 11

Advancing to step 4:
11 goes into 107 9 times with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 789.0
Subtract 99 from 107 to get 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 11

Advancing to step 5:
If we divide 82 by 11, we get 7 and a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 7897.0
If we take 77 away from 82, we end up with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 11

Step 6:
11 goes into 51 4 times with a remainder of 7.
The next digit of our result is 4. 
Result so far: 78974.0
If we subtract 44 from 51, we 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.

Step 7:
11 can be fit into 70 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 78974.6
Subtract 66 from 70 to 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.

Let's proceed to step 8:
11 goes into 40 3 times with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 78974.63
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.

Let's proceed to step 9:
When dividing 70 by 11, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 78974.636
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.

On to step 10:
The number 11 fits into 40 3 times, leaving a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 78974.6363
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.

Going ahead to step 11:
11 goes into 70 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 78974.63636
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.

Moving on to step 12:
11 can be fit into 40 3 times, resulting in a remainder of 7.
The next digit of our result is 3. 
Result so far: 78974.636363
If we subtract 33 from 40, we 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.

Going ahead to step 13:
11 can be fit into 70 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 78974.6363636
If we take 66 away from 70, we end up 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.

On to step 14:
The number 11 fits into 40 3 times, leaving a remainder of 7.
The next digit of our result is 3. 
Result so far: 78974.63636363
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.

The quotient of the division is 78974.63636363, and the remainder is 7e-09.
