Let's divide 643074 by 25
The aim is to understand the frequency of 25 in 643074.

Moving on to step 1:
6 divided by 25 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 25

Moving on to step 2:
When dividing 64 by 25, we get 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 50 away from 64, we end up with 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 25

Step 3:
The number 25 fits into 143 5 times, leaving a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
The remainder is 18 after subtracting 125 from 143.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 25

Moving on to step 4:
When dividing 180 by 25, we get 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 257.0
Subtracting 175 from 180 leaves us with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 25

On to step 5:
25 can be fit into 57 2 times, resulting in a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 2572.0
If we take 50 away from 57, we end up with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 25

Going ahead to step 6:
The number 25 fits into 74 2 times, leaving a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 25722.0
If we take 50 away from 74, 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.

Moving on to step 7:
25 can be fit into 240 9 times, resulting in a remainder of 15.
The next digit of our result is 9. 
Result so far: 25722.9
Subtracting 225 from 240 leaves us with 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 8:
25 can be fit into 150 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 25722.96
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.

Let's proceed to step 9:
If we divide 0 by 25, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 25722.96
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 10:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 25722.96
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 25722.96 with a balance of 0.0.
