Let's divide 933991 by 11
The aim is to understand the frequency of 11 in 933991.

Advancing to step 1:
When dividing 9 by 11, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 11

On to step 2:
11 can be fit into 93 8 times, resulting in a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 88 away from 93, we end up with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 11

On to step 3:
11 can be fit into 53 4 times, resulting in a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
The remainder is 9 after subtracting 44 from 53.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 11

Moving on to step 4:
11 can be fit into 99 9 times, resulting in a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 849.0
If we subtract 99 from 99, we get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 11

Advancing to step 5:
The number 11 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 8490.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 11

Going ahead to step 6:
When dividing 91 by 11, we get 8 with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 84908.0
Subtracting 88 from 91 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.

On to step 7:
When dividing 30 by 11, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 84908.2
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.

Step 8:
80 divided by 11 is 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 84908.27
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.

On to step 9:
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: 84908.272
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.

Advancing to step 10:
The number 11 fits into 80 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 84908.2727
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.

Moving on to step 11:
11 goes into 30 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 84908.27272
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.

On to step 12:
The number 11 fits into 80 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 84908.272727
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 13:
If we divide 30 by 11, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 84908.2727272
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.

Let's proceed to step 14:
When dividing 80 by 11, we get 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 84908.27272727
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.

The quotient of the division is 84908.27272727, and the remainder is 3e-09.
