25127696 ÷ 18 
The aim is to understand the frequency of 18 in 25127696.

Going ahead to step 1:
18 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 18

Going ahead to step 2:
The number 18 fits into 25 1 times, leaving a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 7 after subtracting 18 from 25.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 18

On to step 3:
71 divided by 18 is 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 54 from 71 leaves us with 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 18

Going ahead to step 4:
If we divide 172 by 18, we get 9 and a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 139.0
If we take 162 away from 172, we end up with 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 18

Advancing to step 5:
18 can be fit into 107 5 times, resulting in a remainder of 17.
Put 5 as the next digit of the answer. 
Result so far: 1395.0
If we subtract 90 from 107, we get 17.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 18

Going ahead to step 6:
If we divide 176 by 18, we get 9 and a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 13959.0
If we take 162 away from 176, we end up with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 18

Going ahead to step 7:
When dividing 149 by 18, we get 8 with a remainder of 5.
The next digit of our result is 8. 
Result so far: 139598.0
Subtracting 144 from 149 leaves us with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 18

Going ahead to step 8:
If we divide 56 by 18, we get 3 and a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 1395983.0
If we take 54 away from 56, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
When dividing 20 by 18, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1395983.1
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
20 divided by 18 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1395983.11
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 1395983.11, and the remainder is 0.002.
