65747569 ÷ 25 
The aim is to understand the frequency of 25 in 65747569.

Going ahead to step 1:
25 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 25

On to step 2:
25 goes into 65 2 times with a remainder of 15.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 50 from 65, we get 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 25

Let's proceed to step 3:
When dividing 157 by 25, we get 6 with a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Deduct 150 from 157 and we're left with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 25

Step 4:
74 divided by 25 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 262.0
Deduct 50 from 74 and we're left with 24.
Fetch the next digit (7) from the dividend, attach it to 24 and continue: 247 / 25

On to step 5:
If we divide 247 by 25, we get 9 and a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 2629.0
If we subtract 225 from 247, we get 22.
Append the next digit (5) from the dividend to 22 and continue with: 225 / 25

Step 6:
25 can be fit into 225 9 times, resulting in a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 26299.0
If we take 225 away from 225, we end up with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 25

Step 7:
25 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 262990.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 25

Step 8:
When dividing 69 by 25, we get 2 with a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 2629902.0
If we take 50 away from 69, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 9:
25 can be fit into 190 7 times, resulting in a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 2629902.7
If we subtract 175 from 190, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
25 can be fit into 150 6 times, resulting in a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 2629902.76
If we subtract 150 from 150, 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.

Advancing to step 11:
The number 25 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 2629902.76
If we take 0 away from 0, we end up 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.

Step 12:
0 divided by 25 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 2629902.76
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.

After the division, we end up with 2629902.76 and a remainder of 0.0.
