We look at the division of 74624 by 25 
The aim is to understand the frequency of 25 in 74624.

Step 1:
When dividing 7 by 25, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 25

On to step 2:
74 divided by 25 is 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 50 from 74 and we're left with 24.
Grab the next digit (6) from the dividend, add it to 24, then carry on: 246 / 25

Going ahead to step 3:
The number 25 fits into 246 9 times, leaving a remainder of 21.
The next digit of our result is 9. 
Result so far: 29.0
Subtracting 225 from 246 leaves us with 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 25

On to step 4:
If we divide 212 by 25, we get 8 and a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 298.0
If we take 200 away from 212, we end up with 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 25

Advancing to step 5:
If we divide 124 by 25, we get 4 and a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 2984.0
Deduct 100 from 124 and we're left 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.

Let's proceed to step 6:
The number 25 fits into 240 9 times, leaving a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 2984.9
If we subtract 225 from 240, 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.

Moving on to step 7:
When dividing 150 by 25, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 2984.96
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.

Step 8:
When dividing 0 by 25, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2984.96
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.

Let's proceed to step 9:
When dividing 0 by 25, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2984.96
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 2984.96 with a balance of 0.0.
