864309 divided by 11 
The aim is to understand the frequency of 11 in 864309.

Advancing to step 1:
11 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 11

Step 2:
11 can be fit into 86 7 times, resulting in a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 77 from 86 leaves us with 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 11

Going ahead to step 3:
11 can be fit into 94 8 times, resulting in a remainder of 6.
The next digit of our result is 8. 
Result so far: 78.0
If we subtract 88 from 94, we get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 11

Let's proceed to step 4:
11 goes into 63 5 times with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 785.0
The remainder is 8 after subtracting 55 from 63.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 11

Going ahead to step 5:
The number 11 fits into 80 7 times, leaving a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 7857.0
If we subtract 77 from 80, we get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 11

On to step 6:
When dividing 39 by 11, we get 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 78573.0
Subtract 33 from 39 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.

Advancing to step 7:
The number 11 fits into 60 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 78573.5
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 8:
50 divided by 11 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 78573.54
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.

Moving on to step 9:
When dividing 60 by 11, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 78573.545
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 10:
11 can be fit into 50 4 times, resulting in a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 78573.5454
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.

Step 11:
The number 11 fits into 60 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 78573.54545
Subtract 55 from 60 to 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.

Moving on to step 12:
11 goes into 50 4 times with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 78573.545454
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.

Going ahead to step 13:
If we divide 60 by 11, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 78573.5454545
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.

Advancing to step 14:
When dividing 50 by 11, we get 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 78573.54545454
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.

After the division, we end up with 78573.54545454 and a remainder of 6e-09.
