355562 ÷ 25 
The aim is to understand the frequency of 25 in 355562.

Let's proceed to step 1:
If we divide 3 by 25, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
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

Let's proceed to step 2:
The number 25 fits into 35 1 times, leaving a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 25 from 35 and we're left with 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 25

Going ahead to step 3:
If we divide 105 by 25, we get 4 and a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 5 after subtracting 100 from 105.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 25

Step 4:
If we divide 55 by 25, we get 2 and a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 142.0
Deduct 50 from 55 and we're left with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 25

Let's proceed to step 5:
When dividing 56 by 25, we get 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 1422.0
Deduct 50 from 56 and we're left with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 25

On to step 6:
25 goes into 62 2 times with a remainder of 12.
The next digit of our result is 2. 
Result so far: 14222.0
The remainder is 12 after subtracting 50 from 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
If we divide 120 by 25, we get 4 and a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 14222.4
Subtract 100 from 120 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:
200 divided by 25 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 14222.48
If we take 200 away from 200, 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.

Step 9:
25 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 14222.48
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.

Going ahead to step 10:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 14222.48
The remainder is 0 after subtracting 0 from 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 result is 14222.48 with a remainder of 0.0.
