We're dividing 782598 by 25 
The aim is to understand the frequency of 25 in 782598.

Moving on to step 1:
The number 25 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 25

Going ahead to step 2:
25 goes into 78 3 times with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 75 from 78 leaves us with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 25

On to step 3:
If we divide 32 by 25, we get 1 and a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
If we subtract 25 from 32, we get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 25

Let's proceed to step 4:
When dividing 75 by 25, we get 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 313.0
Subtract 75 from 75 to get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 25

Let's proceed to step 5:
When dividing 9 by 25, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 3130.0
Subtract 0 from 9 to get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 25

Advancing to step 6:
25 goes into 98 3 times with a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 31303.0
Subtracting 75 from 98 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
25 goes into 230 9 times with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 31303.9
Deduct 225 from 230 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
If we divide 50 by 25, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 31303.92
Subtract 50 from 50 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 9:
25 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 31303.92
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.

Moving on to step 10:
25 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 31303.92
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 31303.92 and a remainder of 0.0.
