We're dividing 646966 by 11 
The aim is to understand the frequency of 11 in 646966.

Let's proceed to step 1:
11 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 11

Going ahead to step 2:
If we divide 64 by 11, we get 5 and a remainder of 9.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 55 from 64 to get 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 11

Step 3:
11 goes into 96 8 times with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 58.0
If we take 88 away from 96, we end up with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 11

Advancing to step 4:
11 can be fit into 89 8 times, resulting in a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 588.0
The remainder is 1 after subtracting 88 from 89.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 11

Advancing to step 5:
If we divide 16 by 11, we get 1 and a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 5881.0
Subtract 11 from 16 to get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 11

Going ahead to step 6:
If we divide 56 by 11, we get 5 and a remainder of 1.
The next digit of our result is 5. 
Result so far: 58815.0
Subtract 55 from 56 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
11 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 58815.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
When dividing 100 by 11, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 58815.09
Deduct 99 from 100 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
11 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 58815.09
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
11 can be fit into 100 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 58815.0909
If we subtract 99 from 100, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 11:
10 divided by 11 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 58815.0909
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
11 goes into 100 9 times with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 58815.090909
Subtracting 99 from 100 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 13:
11 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 58815.090909
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
When dividing 100 by 11, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 58815.09090909
Deduct 99 from 100 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 58815.09090909 with a remainder of 1e-09.
