We look at the division of 25892572 by 25 
The aim is to understand the frequency of 25 in 25892572.

Let's proceed to step 1:
The number 25 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 25

Step 2:
When dividing 25 by 25, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 25 from 25, we get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 25

On to step 3:
The number 25 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 8, we get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 25

Moving on to step 4:
If we divide 89 by 25, we get 3 and a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 103.0
Deduct 75 from 89 and we're left with 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 25

Advancing to step 5:
25 goes into 142 5 times with a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 1035.0
Subtract 125 from 142 to get 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 25

Going ahead to step 6:
The number 25 fits into 175 7 times, leaving a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 10357.0
If we subtract 175 from 175, we get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 25

Step 7:
25 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 103570.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 25

Going ahead to step 8:
The number 25 fits into 72 2 times, leaving a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 1035702.0
Subtracting 50 from 72 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.

Step 9:
The number 25 fits into 220 8 times, leaving a remainder of 20.
The next digit of our result is 8. 
Result so far: 1035702.8
Subtract 200 from 220 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
200 divided by 25 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 1035702.88
If we subtract 200 from 200, we 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.

The final outcome is 1035702.88, with a leftover of 0.0.
