We look at the division of 633691 by 11 
The aim is to understand the frequency of 11 in 633691.

Let's proceed to step 1:
If we divide 6 by 11, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 11

Going ahead to step 2:
When dividing 63 by 11, we get 5 with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 55 from 63, we get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 11

On to step 3:
11 can be fit into 83 7 times, resulting in a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
If we take 77 away from 83, we end up with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 11

On to step 4:
66 divided by 11 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 576.0
Deduct 66 from 66 and we're left with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 11

Advancing to step 5:
11 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 5760.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 11

Moving on to step 6:
11 goes into 91 8 times with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 57608.0
Deduct 88 from 91 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 7:
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: 57608.2
If we take 22 away from 30, we end up 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.

On to step 8:
11 goes into 80 7 times with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 57608.27
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.

On to step 9:
When dividing 30 by 11, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 57608.272
If we take 22 away from 30, we end up 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.

On to step 10:
11 can be fit into 80 7 times, resulting in a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 57608.2727
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.

Step 11:
When dividing 30 by 11, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 57608.27272
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.

Advancing to step 12:
11 goes into 80 7 times with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 57608.272727
Subtracting 77 from 80 leaves us 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.

Moving on to step 13:
11 goes into 30 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 57608.2727272
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.

Going ahead to step 14:
If we divide 80 by 11, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 57608.27272727
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.

The quotient of the division is 57608.27272727, and the remainder is 3e-09.
