We're dividing 516729 by 25 
The aim is to understand the frequency of 25 in 516729.

Moving on to step 1:
5 divided by 25 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 25

Going ahead to step 2:
When dividing 51 by 25, we get 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 50 from 51 leaves us with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 25

Going ahead to step 3:
16 divided by 25 is 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Deduct 0 from 16 and we're left with 16.
Bring next digit (7) of the dividend behind the 16 and repeat the process: 167 / 25

Going ahead to step 4:
25 goes into 167 6 times with a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 206.0
Subtract 150 from 167 to get 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 25

Step 5:
172 divided by 25 is 6 with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 2066.0
Subtracting 150 from 172 leaves us with 22.
Bring next digit (9) of the dividend behind the 22 and repeat the process: 229 / 25

Let's proceed to step 6:
If we divide 229 by 25, we get 9 and a remainder of 4.
The next digit of our result is 9. 
Result so far: 20669.0
If we take 225 away from 229, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
The number 25 fits into 40 1 times, leaving a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 20669.1
If we take 25 away from 40, we end up 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.

Step 8:
The number 25 fits into 150 6 times, leaving a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 20669.16
Subtract 150 from 150 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.

Step 9:
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: 20669.16
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:
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: 20669.16
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.

In conclusion, the division gives 20669.16 with a balance of 0.0.
