18816 divided by 25 
The aim is to understand the frequency of 25 in 18816.

Going ahead to step 1:
25 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 25

Let's proceed to step 2:
When dividing 18 by 25, we get 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 25

Moving on to step 3:
When dividing 188 by 25, we get 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 175 from 188 to get 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 25

Moving on to step 4:
25 can be fit into 131 5 times, resulting in a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
The remainder is 6 after subtracting 125 from 131.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 25

Step 5:
If we divide 66 by 25, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 752.0
Deduct 50 from 66 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 6:
The number 25 fits into 160 6 times, leaving a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 752.6
If we take 150 away from 160, we end up 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.

On to step 7:
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: 752.64
If we take 100 away from 100, 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 8:
0 divided by 25 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 752.64
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.

Let's proceed to step 9:
25 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 752.64
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.

The final outcome is 752.64, with a leftover of 0.0.
