We're dividing 33511519 by 11 
The aim is to understand the frequency of 11 in 33511519.

Going ahead to step 1:
When dividing 3 by 11, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 11

Advancing to step 2:
11 can be fit into 33 3 times, resulting in a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 33 from 33 to get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 11

On to step 3:
11 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 11

On to step 4:
51 divided by 11 is 4 with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 304.0
Deduct 44 from 51 and we're left with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 11

Let's proceed to step 5:
The number 11 fits into 71 6 times, leaving a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 3046.0
If we take 66 away from 71, we end up with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 11

Moving on to step 6:
When dividing 55 by 11, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 30465.0
Subtract 55 from 55 to get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 11

Going ahead to step 7:
11 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 304650.0
Subtract 0 from 1 to get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 11

On to step 8:
If we divide 19 by 11, we get 1 and a remainder of 8.
The next digit of our result is 1. 
Result so far: 3046501.0
If we subtract 11 from 19, 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.

Moving on to step 9:
When dividing 80 by 11, we get 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 3046501.7
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.

Advancing to step 10:
30 divided by 11 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 3046501.72
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.

Step 11:
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: 3046501.727
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.

On to step 12:
The number 11 fits into 30 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 3046501.7272
The remainder is 8 after subtracting 22 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
When dividing 80 by 11, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 3046501.72727
The remainder is 3 after subtracting 77 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 14:
11 goes into 30 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 3046501.727272
Deduct 22 from 30 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.

Advancing to step 15:
If we divide 80 by 11, we get 7 and a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 3046501.7272727
The remainder is 3 after subtracting 77 from 80.
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 16:
The number 11 fits into 30 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 3046501.72727272
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.

The quotient of the division is 3046501.72727272, and the remainder is 8e-09.
