We look at the division of 16526670 by 111 
The aim is to understand the frequency of 111 in 16526670.

Let's proceed to step 1:
111 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 111

Advancing to step 2:
If we divide 16 by 111, we get 0 and a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 111

Going ahead to step 3:
165 divided by 111 is 1 with a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 111 from 165 and we're left with 54.
Include the next digit (2) from the dividend after 54, then repeat: 542 / 111

Moving on to step 4:
The number 111 fits into 542 4 times, leaving a remainder of 98.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 444 from 542 leaves us with 98.
Append the next digit (6) from the dividend to 98 and continue with: 986 / 111

Let's proceed to step 5:
111 can be fit into 986 8 times, resulting in a remainder of 98.
Record the quotient 8 as the next digit in the result. 
Result so far: 148.0
Deduct 888 from 986 and we're left with 98.
Bring next digit (6) of the dividend behind the 98 and repeat the process: 986 / 111

Step 6:
When dividing 986 by 111, we get 8 with a remainder of 98.
Use 8 as the next digit of our solution. 
Result so far: 1488.0
If we subtract 888 from 986, we get 98.
Include the next digit (7) from the dividend after 98, then repeat: 987 / 111

Let's proceed to step 7:
When dividing 987 by 111, we get 8 with a remainder of 99.
Write down 8 as next digit of the result. 
Result so far: 14888.0
Subtract 888 from 987 to get 99.
Append the next digit (0) from the dividend to 99 and continue with: 990 / 111

Advancing to step 8:
If we divide 990 by 111, we get 8 and a remainder of 102.
Use 8 as the next digit of our solution. 
Result so far: 148888.0
Subtract 888 from 990 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 9:
The number 111 fits into 1020 9 times, leaving a remainder of 21.
The next digit of our result is 9. 
Result so far: 148888.9
The remainder is 21 after subtracting 999 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 10:
210 divided by 111 is 1 with a remainder of 99.
The number 1 becomes the next digit in our result. 
Result so far: 148888.91
If we take 111 away from 210, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Let's proceed to step 11:
111 can be fit into 990 8 times, resulting in a remainder of 102.
Use 8 as the next digit of our solution. 
Result so far: 148888.918
Deduct 888 from 990 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 12:
1020 divided by 111 is 9 with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 148888.9189
If we take 999 away from 1020, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 13:
111 can be fit into 210 1 times, resulting in a remainder of 99.
Use 1 as the next digit of our solution. 
Result so far: 148888.91891
Subtract 111 from 210 to get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 14:
When dividing 990 by 111, we get 8 with a remainder of 102.
The number 8 becomes the next digit in our result. 
Result so far: 148888.918918
Deduct 888 from 990 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 15:
When dividing 1020 by 111, we get 9 with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 148888.9189189
If we take 999 away from 1020, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 16:
If we divide 210 by 111, we get 1 and a remainder of 99.
The number 1 becomes the next digit in our result. 
Result so far: 148888.91891891
If we subtract 111 from 210, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

The final outcome is 148888.91891891, with a leftover of 9.9e-08.
