We look at the division of 25378792 by 23 
The aim is to understand the frequency of 23 in 25378792.

Moving on to step 1:
The number 23 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 23

Advancing to step 2:
23 goes into 25 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 23 from 25 leaves us with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 23

Let's proceed to step 3:
23 can be fit into 23 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 0 after subtracting 23 from 23.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 23

Moving on to step 4:
The number 23 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 110.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 23

Let's proceed to step 5:
When dividing 78 by 23, we get 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 1103.0
If we subtract 69 from 78, we get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 23

Moving on to step 6:
23 can be fit into 97 4 times, resulting in a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 11034.0
Subtracting 92 from 97 leaves us with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 23

Advancing to step 7:
When dividing 59 by 23, we get 2 with a remainder of 13.
The next digit of our result is 2. 
Result so far: 110342.0
Subtract 46 from 59 to get 13.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 23

Going ahead to step 8:
When dividing 132 by 23, we get 5 with a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 1103425.0
Subtracting 115 from 132 leaves us 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 9:
170 divided by 23 is 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 1103425.7
Deduct 161 from 170 and we're left 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.

On to step 10:
23 goes into 90 3 times with a remainder of 21.
The next digit of our result is 3. 
Result so far: 1103425.73
Deduct 69 from 90 and we're left 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 11:
The number 23 fits into 210 9 times, leaving a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 1103425.739
If we subtract 207 from 210, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 12:
The number 23 fits into 30 1 times, leaving a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1103425.7391
Subtract 23 from 30 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 13:
If we divide 70 by 23, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 1103425.73913
If we take 69 away from 70, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 14:
23 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 1103425.73913
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 15:
If we divide 100 by 23, we get 4 and a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 1103425.7391304
The remainder is 8 after subtracting 92 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 16:
23 goes into 80 3 times with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 1103425.73913043
If we take 69 away from 80, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 1103425.73913043 with a remainder of 1.1e-08.
