The aim is to understand the frequency of 111 in 17458913.

Moving on to step 1:
111 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 111

Moving on to step 2:
17 divided by 111 is 0 with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 111

On to step 3:
If we divide 174 by 111, we get 1 and a remainder of 63.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 111 from 174 to get 63.
Grab the next digit (5) from the dividend, add it to 63, then carry on: 635 / 111

On to step 4:
The number 111 fits into 635 5 times, leaving a remainder of 80.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 555 from 635 and we're left with 80.
Bring next digit (8) of the dividend behind the 80 and repeat the process: 808 / 111

On to step 5:
When dividing 808 by 111, we get 7 with a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 157.0
The remainder is 31 after subtracting 777 from 808.
Include the next digit (9) from the dividend after 31, then repeat: 319 / 111

Moving on to step 6:
When dividing 319 by 111, we get 2 with a remainder of 97.
The number 2 becomes the next digit in our result. 
Result so far: 1572.0
Deduct 222 from 319 and we're left with 97.
Grab the next digit (1) from the dividend, add it to 97, then carry on: 971 / 111

Advancing to step 7:
111 can be fit into 971 8 times, resulting in a remainder of 83.
Put 8 as the next digit of the answer. 
Result so far: 15728.0
The remainder is 83 after subtracting 888 from 971.
Include the next digit (3) from the dividend after 83, then repeat: 833 / 111

Let's proceed to step 8:
833 divided by 111 is 7 with a remainder of 56.
Use 7 as the next digit of our solution. 
Result so far: 157287.0
If we subtract 777 from 833, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 9:
111 can be fit into 560 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 157287.5
If we subtract 555 from 560, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
50 divided by 111 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 157287.5
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
When dividing 500 by 111, we get 4 with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 157287.504
If we take 444 away from 500, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
If we divide 560 by 111, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 157287.5045
If we subtract 555 from 560, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 13:
The number 111 fits into 50 0 times, leaving a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 157287.5045
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 14:
500 divided by 111 is 4 with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 157287.504504
The remainder is 56 after subtracting 444 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 15:
If we divide 560 by 111, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 157287.5045045
Deduct 555 from 560 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 16:
If we divide 50 by 111, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 157287.5045045
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 157287.5045045 with a remainder of 5e-08.
