We look at the division of 249106 by 23 
The aim is to understand the frequency of 23 in 249106.

On to step 1:
2 divided by 23 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 23

Step 2:
24 divided by 23 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 23 from 24 to get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 23

On to step 3:
When dividing 19 by 23, we get 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 19, we get 19.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 23

Step 4:
191 divided by 23 is 8 with a remainder of 7.
The next digit of our result is 8. 
Result so far: 108.0
Subtracting 184 from 191 leaves us with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 23

Step 5:
23 can be fit into 70 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 1083.0
Subtracting 69 from 70 leaves us with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 23

Moving on to step 6:
If we divide 16 by 23, we get 0 and a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 10830.0
Subtracting 0 from 16 leaves us 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.

Let's proceed to step 7:
160 divided by 23 is 6 with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 10830.6
The remainder is 22 after subtracting 138 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 8:
The number 23 fits into 220 9 times, leaving a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 10830.69
If we subtract 207 from 220, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 9:
130 divided by 23 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 10830.695
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.

Let's proceed to step 10:
The number 23 fits into 150 6 times, leaving a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 10830.6956
Subtracting 138 from 150 leaves us with 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:
When dividing 120 by 23, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 10830.69565
If we subtract 115 from 120, 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.

Advancing to step 12:
50 divided by 23 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 10830.695652
Deduct 46 from 50 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
The number 23 fits into 40 1 times, leaving a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 10830.6956521
If we take 23 away from 40, we end up 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 14:
170 divided by 23 is 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 10830.69565217
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 10830.69565217 with a remaining 9e-09.
