We're dividing 17315369 by 111 
The aim is to understand the frequency of 111 in 17315369.

Moving on to step 1:
1 divided by 111 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 111

On to step 2:
111 goes into 17 0 times with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 111

Moving on to step 3:
The number 111 fits into 173 1 times, leaving a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 111 from 173 and we're left with 62.
Take the next digit (1) from the dividend and append it to 62, then repeat: 621 / 111

Let's proceed to step 4:
111 goes into 621 5 times with a remainder of 66.
Use 5 as the next digit of our solution. 
Result so far: 15.0
The remainder is 66 after subtracting 555 from 621.
Bring next digit (5) of the dividend behind the 66 and repeat the process: 665 / 111

On to step 5:
The number 111 fits into 665 5 times, leaving a remainder of 110.
The number 5 becomes the next digit in our result. 
Result so far: 155.0
If we subtract 555 from 665, we get 110.
Include the next digit (3) from the dividend after 110, then repeat: 1103 / 111

Moving on to step 6:
If we divide 1103 by 111, we get 9 and a remainder of 104.
The next digit of our result is 9. 
Result so far: 1559.0
Subtract 999 from 1103 to get 104.
Grab the next digit (6) from the dividend, add it to 104, then carry on: 1046 / 111

Let's proceed to step 7:
When dividing 1046 by 111, we get 9 with a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 15599.0
Subtracting 999 from 1046 leaves us with 47.
Fetch the next digit (9) from the dividend, attach it to 47 and continue: 479 / 111

Let's proceed to step 8:
111 goes into 479 4 times with a remainder of 35.
The next digit of our result is 4. 
Result so far: 155994.0
If we take 444 away from 479, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
The number 111 fits into 350 3 times, leaving a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 155994.3
The remainder is 17 after subtracting 333 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 10:
When dividing 170 by 111, we get 1 with a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 155994.31
If we subtract 111 from 170, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 11:
111 can be fit into 590 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 155994.315
Subtracting 555 from 590 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 12:
When dividing 350 by 111, we get 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 155994.3153
Subtract 333 from 350 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 13:
If we divide 170 by 111, we get 1 and a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 155994.31531
If we take 111 away from 170, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 14:
When dividing 590 by 111, we get 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 155994.315315
Subtract 555 from 590 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 15:
If we divide 350 by 111, we get 3 and a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 155994.3153153
Deduct 333 from 350 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 16:
The number 111 fits into 170 1 times, leaving a remainder of 59.
The next digit of our result is 1. 
Result so far: 155994.31531531
The remainder is 59 after subtracting 111 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

After the division, we end up with 155994.31531531 and a remainder of 5.9e-08.
