We look at the division of 111612 by 23 
The aim is to understand the frequency of 23 in 111612.

Step 1:
When dividing 1 by 23, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 23

Going ahead to step 2:
When dividing 11 by 23, we get 0 with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 23

On to step 3:
If we divide 111 by 23, we get 4 and a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 92 from 111, we get 19.
Fetch the next digit (6) from the dividend, attach it to 19 and continue: 196 / 23

Step 4:
If we divide 196 by 23, we get 8 and a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 48.0
Subtract 184 from 196 to get 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 23

Moving on to step 5:
If we divide 121 by 23, we get 5 and a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 485.0
If we subtract 115 from 121, we get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 23

Advancing to step 6:
If we divide 62 by 23, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 4852.0
Deduct 46 from 62 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
If we divide 160 by 23, we get 6 and a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 4852.6
Subtracting 138 from 160 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 8:
23 can be fit into 220 9 times, resulting in a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 4852.69
Subtracting 207 from 220 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 9:
23 goes into 130 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 4852.695
Subtracting 115 from 130 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 10:
If we divide 150 by 23, we get 6 and a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 4852.6956
If we subtract 138 from 150, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
23 goes into 120 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 4852.69565
Subtract 115 from 120 to 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 12:
The number 23 fits into 50 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 4852.695652
The remainder is 4 after subtracting 46 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
When dividing 40 by 23, we get 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 4852.6956521
If we subtract 23 from 40, we 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.

Advancing to step 14:
When dividing 170 by 23, we get 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 4852.69565217
If we take 161 away from 170, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Our division results in 4852.69565217 with a remaining 9e-09.
