We look at the division of 645167 by 11 
The aim is to understand the frequency of 11 in 645167.

On to step 1:
11 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 11

Let's proceed to step 2:
11 goes into 64 5 times with a remainder of 9.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 9 after subtracting 55 from 64.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 11

Going ahead to step 3:
When dividing 95 by 11, we get 8 with a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 58.0
The remainder is 7 after subtracting 88 from 95.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 11

Step 4:
11 can be fit into 71 6 times, resulting in a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 586.0
If we subtract 66 from 71, we get 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 11

Step 5:
11 goes into 56 5 times with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 5865.0
Subtract 55 from 56 to get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 11

Moving on to step 6:
If we divide 17 by 11, we get 1 and a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 58651.0
The remainder is 6 after subtracting 11 from 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
When dividing 60 by 11, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 58651.5
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.

Advancing to step 8:
When dividing 50 by 11, we get 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 58651.54
Subtracting 44 from 50 leaves us 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.

Let's proceed to step 9:
11 can be fit into 60 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 58651.545
Subtracting 55 from 60 leaves us 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.

Let's proceed to step 10:
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: 58651.5454
The remainder is 6 after subtracting 44 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 11:
60 divided by 11 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 58651.54545
Subtracting 55 from 60 leaves us 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.

Let's proceed to step 12:
If we divide 50 by 11, we get 4 and a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 58651.545454
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.

Moving on to step 13:
60 divided by 11 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 58651.5454545
If we subtract 55 from 60, we 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.

On to step 14:
When dividing 50 by 11, we get 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 58651.54545454
The remainder is 6 after subtracting 44 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 58651.54545454 with a remainder of 6e-09.
