355337 divided by 25 
The aim is to understand the frequency of 25 in 355337.

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.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 25

On to step 2:
If we divide 35 by 25, we get 1 and a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 25 from 35 leaves us with 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 25

Moving on to step 3:
105 divided by 25 is 4 with a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 100 from 105, we get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 25

Step 4:
The number 25 fits into 53 2 times, leaving a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 142.0
The remainder is 3 after subtracting 50 from 53.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 25

Step 5:
33 divided by 25 is 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1421.0
Subtract 25 from 33 to get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 25

Step 6:
If we divide 87 by 25, we get 3 and a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 14213.0
Deduct 75 from 87 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
25 goes into 120 4 times with a remainder of 20.
The next digit of our result is 4. 
Result so far: 14213.4
The remainder is 20 after subtracting 100 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On 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: 14213.48
The remainder is 0 after subtracting 200 from 200.
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 9:
0 divided by 25 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 14213.48
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.

Going ahead 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: 14213.48
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.

The final outcome is 14213.48, with a leftover of 0.0.
