We look at the division of 5094141 by 25 
The aim is to understand the frequency of 25 in 5094141.

On to step 1:
When dividing 5 by 25, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 25

Advancing to step 2:
25 goes into 50 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 50 from 50 and we're left with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 25

Step 3:
The number 25 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we subtract 0 from 9, we get 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 25

Let's proceed to step 4:
25 goes into 94 3 times with a remainder of 19.
The next digit of our result is 3. 
Result so far: 203.0
If we subtract 75 from 94, we get 19.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 25

Let's proceed to step 5:
When dividing 191 by 25, we get 7 with a remainder of 16.
The next digit of our result is 7. 
Result so far: 2037.0
The remainder is 16 after subtracting 175 from 191.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 25

Moving on to step 6:
164 divided by 25 is 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 20376.0
If we subtract 150 from 164, we get 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 25

Going ahead to step 7:
If we divide 141 by 25, we get 5 and a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 203765.0
Deduct 125 from 141 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.

On to step 8:
25 can be fit into 160 6 times, resulting in a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 203765.6
The remainder is 10 after subtracting 150 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
25 goes into 100 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 203765.64
Subtracting 100 from 100 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.

Moving on to step 10:
When dividing 0 by 25, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 203765.64
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.

Moving on to step 11:
The number 25 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 203765.64
Deduct 0 from 0 and we're left 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 result is 203765.64 with a remainder of 0.0.
