We're dividing 63339508 by 25 
The aim is to understand the frequency of 25 in 63339508.

Step 1:
The number 25 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 25

Step 2:
25 goes into 63 2 times with a remainder of 13.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 50 from 63, we get 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 25

Let's proceed to step 3:
25 can be fit into 133 5 times, resulting in a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 25.0
The remainder is 8 after subtracting 125 from 133.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 25

Advancing to step 4:
25 goes into 83 3 times with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 253.0
The remainder is 8 after subtracting 75 from 83.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 25

Let's proceed to step 5:
When dividing 89 by 25, we get 3 with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 2533.0
Subtracting 75 from 89 leaves us with 14.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 25

Moving on to step 6:
145 divided by 25 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 25335.0
If we take 125 away from 145, we end up with 20.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 25

Moving on to step 7:
25 goes into 200 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 253358.0
Subtracting 200 from 200 leaves us with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 25

Step 8:
If we divide 8 by 25, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 2533580.0
Deduct 0 from 8 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
25 goes into 80 3 times with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 2533580.3
If we subtract 75 from 80, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
If we divide 50 by 25, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2533580.32
If we subtract 50 from 50, 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.

Going ahead to step 11:
0 divided by 25 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2533580.32
If we subtract 0 from 0, 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.

Let's proceed to step 12:
0 divided by 25 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2533580.32
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.

After the division, we end up with 2533580.32 and a remainder of 0.0.
