361853 divided by 25 
The aim is to understand the frequency of 25 in 361853.

Going ahead to step 1:
The number 25 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 25

Let's proceed to step 2:
25 can be fit into 36 1 times, resulting in a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 25 from 36 to get 11.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 25

Step 3:
25 goes into 111 4 times with a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 100 away from 111, we end up with 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 25

On to step 4:
When dividing 118 by 25, we get 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 144.0
Subtracting 100 from 118 leaves us with 18.
Fetch the next digit (5) from the dividend, attach it to 18 and continue: 185 / 25

Going ahead to step 5:
The number 25 fits into 185 7 times, leaving a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 1447.0
The remainder is 10 after subtracting 175 from 185.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 25

Going ahead to step 6:
25 goes into 103 4 times with a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 14474.0
Subtracting 100 from 103 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
The number 25 fits into 30 1 times, leaving a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 14474.1
Subtracting 25 from 30 leaves us 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.

Step 8:
50 divided by 25 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 14474.12
If we subtract 50 from 50, 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.

Let's proceed to step 9:
When dividing 0 by 25, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 14474.12
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.

On to step 10:
25 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 14474.12
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 14474.12, with a leftover of 0.0.
