We divide 513669 by 25
The aim is to understand the frequency of 25 in 513669.

Going ahead to step 1:
If we divide 5 by 25, we get 0 and 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.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 25

Going ahead to step 2:
If we divide 51 by 25, we get 2 and a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 50 from 51 and we're left with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 25

Going ahead to step 3:
If we divide 13 by 25, we get 0 and a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we subtract 0 from 13, we get 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 25

On to step 4:
136 divided by 25 is 5 with a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 205.0
The remainder is 11 after subtracting 125 from 136.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 25

Let's proceed to step 5:
If we divide 116 by 25, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 2054.0
Subtracting 100 from 116 leaves us with 16.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 25

Going ahead to step 6:
The number 25 fits into 169 6 times, leaving a remainder of 19.
Write down 6 as next digit of the result. 
Result so far: 20546.0
If we take 150 away from 169, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
25 can be fit into 190 7 times, resulting in a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 20546.7
Subtract 175 from 190 to 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.

Going ahead to step 8:
The number 25 fits into 150 6 times, leaving a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 20546.76
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.

Going ahead to step 9:
25 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 20546.76
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.

Advancing to step 10:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20546.76
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.

In conclusion, the division gives 20546.76 with a balance of 0.0.
