25716 ÷ 18 
The aim is to understand the frequency of 18 in 25716.

Step 1:
18 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 18

Going ahead to step 2:
18 goes into 25 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 18 from 25 leaves us with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 18

Moving on to step 3:
18 can be fit into 77 4 times, resulting in a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we take 72 away from 77, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 18

Let's proceed to step 4:
If we divide 51 by 18, we get 2 and a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 142.0
The remainder is 15 after subtracting 36 from 51.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 18

Going ahead to step 5:
The number 18 fits into 156 8 times, leaving a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 1428.0
If we subtract 144 from 156, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 6:
18 can be fit into 120 6 times, resulting in a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 1428.6
Subtract 108 from 120 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
18 can be fit into 120 6 times, resulting in a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 1428.66
The remainder is 12 after subtracting 108 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 1428.66, and the remainder is 0.012.
