864120 ÷ 11 
The aim is to understand the frequency of 11 in 864120.

Going ahead to step 1:
11 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 11

On to step 2:
If we divide 86 by 11, we get 7 and a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 77 from 86 and we're left with 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 11

Let's proceed to step 3:
11 can be fit into 94 8 times, resulting in a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 78.0
The remainder is 6 after subtracting 88 from 94.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 11

Step 4:
11 goes into 61 5 times with a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 785.0
If we subtract 55 from 61, we get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 11

Moving on to step 5:
If we divide 62 by 11, we get 5 and 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

Step 6:
11 goes into 70 6 times with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 78556.0
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 7:
If we divide 40 by 11, we get 3 and a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 78556.3
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.

Let's proceed to 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
Subtracting 66 from 70 leaves us 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.

Going ahead to step 9:
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: 78556.363
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.

Let's proceed to step 10:
If we divide 70 by 11, we get 6 and a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 78556.3636
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.

Let's proceed to step 11:
11 goes into 40 3 times 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.

Moving on to step 12:
When dividing 70 by 11, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 78556.363636
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.

Let's proceed to step 13:
When dividing 40 by 11, we get 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 78556.3636363
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.

Going ahead to step 14:
70 divided by 11 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
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.

After the division, we end up with 78556.36363636 and a remainder of 4e-09.
