We look at the division of 11504338 by 111 
The aim is to understand the frequency of 111 in 11504338.

Going ahead to step 1:
When dividing 1 by 111, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 111

Advancing to step 2:
111 can be fit into 11 0 times, resulting in a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 111

On to step 3:
111 goes into 115 1 times with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 111 from 115, we get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 111

Going ahead to step 4:
40 divided by 111 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 40 leaves us with 40.
Include the next digit (4) from the dividend after 40, then repeat: 404 / 111

Going ahead to step 5:
The number 111 fits into 404 3 times, leaving a remainder of 71.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
If we take 333 away from 404, we end up with 71.
Grab the next digit (3) from the dividend, add it to 71, then carry on: 713 / 111

Advancing to step 6:
The number 111 fits into 713 6 times, leaving a remainder of 47.
Record the quotient 6 as the next digit in the result. 
Result so far: 1036.0
The remainder is 47 after subtracting 666 from 713.
Take the next digit (3) from the dividend and append it to 47, then repeat: 473 / 111

Moving on to step 7:
473 divided by 111 is 4 with a remainder of 29.
Use 4 as the next digit of our solution. 
Result so far: 10364.0
If we subtract 444 from 473, we get 29.
Include the next digit (8) from the dividend after 29, then repeat: 298 / 111

Going ahead to step 8:
298 divided by 111 is 2 with a remainder of 76.
The next digit of our result is 2. 
Result so far: 103642.0
The remainder is 76 after subtracting 222 from 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 9:
111 can be fit into 760 6 times, resulting in a remainder of 94.
The number 6 becomes the next digit in our result. 
Result so far: 103642.6
Subtracting 666 from 760 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 10:
The number 111 fits into 940 8 times, leaving a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 103642.68
Deduct 888 from 940 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 11:
111 goes into 520 4 times with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 103642.684
Deduct 444 from 520 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 12:
The number 111 fits into 760 6 times, leaving a remainder of 94.
The next digit of our result is 6. 
Result so far: 103642.6846
Subtracting 666 from 760 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 13:
If we divide 940 by 111, we get 8 and a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 103642.68468
If we subtract 888 from 940, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 14:
If we divide 520 by 111, we get 4 and a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 103642.684684
If we take 444 away from 520, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 15:
111 can be fit into 760 6 times, resulting in a remainder of 94.
Use 6 as the next digit of our solution. 
Result so far: 103642.6846846
Subtracting 666 from 760 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 16:
940 divided by 111 is 8 with a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 103642.68468468
If we take 888 away from 940, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 103642.68468468 with a remainder of 5.2e-08.
