We divide 855477 by 25
The aim is to understand the frequency of 25 in 855477.

Going ahead to step 1:
25 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 25

Let's proceed to step 2:
If we divide 85 by 25, we get 3 and a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 75 from 85 leaves us with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 25

Let's proceed to step 3:
25 can be fit into 105 4 times, resulting in a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 34.0
The remainder is 5 after subtracting 100 from 105.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 25

Let's proceed to step 4:
If we divide 54 by 25, we get 2 and a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 342.0
Subtract 50 from 54 to get 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 25

Going ahead to step 5:
47 divided by 25 is 1 with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 3421.0
Subtract 25 from 47 to get 22.
Take the next digit (7) from the dividend and append it to 22, then repeat: 227 / 25

On to step 6:
When dividing 227 by 25, we get 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 34219.0
Subtracting 225 from 227 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
25 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 34219.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
When dividing 200 by 25, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 34219.08
If we subtract 200 from 200, 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.

Moving on to step 9:
0 divided by 25 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 34219.08
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.

Moving on to step 10:
25 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 34219.08
If we subtract 0 from 0, 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.

The final outcome is 34219.08, with a leftover of 0.0.
