We look at the division of 782024 by 25 
The aim is to understand the frequency of 25 in 782024.

Going ahead to step 1:
When dividing 7 by 25, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 25

On to step 2:
The number 25 fits into 78 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 75 from 78 to get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 25

On to step 3:
25 goes into 32 1 times with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtracting 25 from 32 leaves us with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 25

Moving on to step 4:
When dividing 70 by 25, we get 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 312.0
Subtracting 50 from 70 leaves us with 20.
Append the next digit (2) from the dividend to 20 and continue with: 202 / 25

Moving on to step 5:
25 can be fit into 202 8 times, resulting in a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 3128.0
If we take 200 away from 202, we end up with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 25

Step 6:
When dividing 24 by 25, we get 0 with a remainder of 24.
The next digit of our result is 0. 
Result so far: 31280.0
If we take 0 away from 24, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
If we divide 240 by 25, we get 9 and a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 31280.9
The remainder is 15 after subtracting 225 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
When dividing 150 by 25, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 31280.96
If we take 150 away from 150, 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.

Going ahead to step 9:
25 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 31280.96
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.

Step 10:
0 divided by 25 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 31280.96
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.

The final outcome is 31280.96, with a leftover of 0.0.
