124126 divided by 25 
The aim is to understand the frequency of 25 in 124126.

On to step 1:
When dividing 1 by 25, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 25

Advancing to step 2:
12 divided by 25 is 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 25

On to step 3:
25 can be fit into 124 4 times, resulting in a remainder of 24.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 100 from 124 to get 24.
Include the next digit (1) from the dividend after 24, then repeat: 241 / 25

On to step 4:
The number 25 fits into 241 9 times, leaving a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 49.0
If we subtract 225 from 241, we get 16.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 25

Step 5:
The number 25 fits into 162 6 times, leaving a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 496.0
If we subtract 150 from 162, we get 12.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 25

Moving on to step 6:
126 divided by 25 is 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 4965.0
The remainder is 1 after subtracting 125 from 126.
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 7:
10 divided by 25 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 4965.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
If we divide 100 by 25, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4965.04
The remainder is 0 after subtracting 100 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
0 divided by 25 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4965.04
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
25 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4965.04
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 4965.04, with a leftover of 0.0.
