We're dividing 853605 by 25 
The aim is to understand the frequency of 25 in 853605.

Moving on to step 1:
8 divided by 25 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 25

Moving on to step 2:
25 goes into 85 3 times with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 75 from 85 to get 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 25

Step 3:
25 can be fit into 103 4 times, resulting in a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
If we subtract 100 from 103, we get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 25

Step 4:
The number 25 fits into 36 1 times, leaving a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 341.0
If we subtract 25 from 36, we get 11.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 25

Moving on to step 5:
If we divide 110 by 25, we get 4 and a remainder of 10.
The next digit of our result is 4. 
Result so far: 3414.0
If we take 100 away from 110, we end up with 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 25

Going ahead to step 6:
25 can be fit into 105 4 times, resulting in a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 34144.0
If we take 100 away from 105, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
When dividing 50 by 25, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 34144.2
Deduct 50 from 50 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.

Moving on to step 8:
25 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 34144.2
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.

On to step 9:
0 divided by 25 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 34144.2
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.

The final outcome is 34144.2, with a leftover of 0.0.
