355356 ÷ 25 
The aim is to understand the frequency of 25 in 355356.

Step 1:
25 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 25

Going ahead to step 2:
35 divided by 25 is 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 25 away from 35, we end up with 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 25

Advancing to step 3:
When dividing 105 by 25, we get 4 with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 100 from 105, we get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 25

Advancing to step 4:
If we divide 53 by 25, we get 2 and a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 142.0
If we subtract 50 from 53, we get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 25

Advancing to step 5:
35 divided by 25 is 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1421.0
Subtract 25 from 35 to get 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 25

Going ahead to step 6:
106 divided by 25 is 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 14214.0
If we take 100 away from 106, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
25 goes into 60 2 times with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 14214.2
Deduct 50 from 60 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
If we divide 100 by 25, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 14214.24
If we subtract 100 from 100, 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.

On to step 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 14214.24
Subtract 0 from 0 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 10:
When dividing 0 by 25, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 14214.24
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.

Our division results in 14214.24 with a remaining 0.0.
