We look at the division of 820487 by 11 
The aim is to understand the frequency of 11 in 820487.

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
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 11

Advancing to step 2:
82 divided by 11 is 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 77 from 82 leaves us with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 11

On to step 3:
If we divide 50 by 11, we get 4 and a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 74.0
If we subtract 44 from 50, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 11

Advancing to step 4:
The number 11 fits into 64 5 times, leaving a remainder of 9.
The next digit of our result is 5. 
Result so far: 745.0
Subtract 55 from 64 to get 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 11

Advancing to step 5:
98 divided by 11 is 8 with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 7458.0
If we subtract 88 from 98, we get 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 11

Moving on to step 6:
11 goes into 107 9 times with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 74589.0
Deduct 99 from 107 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.

Going ahead to step 7:
80 divided by 11 is 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 74589.7
If we subtract 77 from 80, we 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 8:
The number 11 fits into 30 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 74589.72
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.

Let's proceed to step 9:
If we divide 80 by 11, we get 7 and a remainder of 3.
The next digit of our result is 7. 
Result so far: 74589.727
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.

Advancing to step 10:
11 goes into 30 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 74589.7272
Subtract 22 from 30 to 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.

Let's proceed to step 11:
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: 74589.72727
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.

On to step 12:
11 goes into 30 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 74589.727272
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.

Advancing to step 13:
80 divided by 11 is 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 74589.7272727
Deduct 77 from 80 and we're left 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 14:
If we divide 30 by 11, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 74589.72727272
Subtract 22 from 30 to 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.

The final outcome is 74589.72727272, with a leftover of 8e-09.
