249728 ÷ 18 
The aim is to understand the frequency of 18 in 249728.

Moving on to step 1:
18 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 18

Advancing to step 2:
The number 18 fits into 24 1 times, leaving a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 6 after subtracting 18 from 24.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 18

Let's proceed to step 3:
The number 18 fits into 69 3 times, leaving a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 54 from 69 and we're left with 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 18

Let's proceed to step 4:
18 goes into 157 8 times with a remainder of 13.
The next digit of our result is 8. 
Result so far: 138.0
Deduct 144 from 157 and we're left with 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 18

On to step 5:
If we divide 132 by 18, we get 7 and a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 1387.0
Subtract 126 from 132 to get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 18

Moving on to step 6:
The number 18 fits into 68 3 times, leaving a remainder of 14.
The next digit of our result is 3. 
Result so far: 13873.0
If we subtract 54 from 68, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
The number 18 fits into 140 7 times, leaving a remainder of 14.
The next digit of our result is 7. 
Result so far: 13873.7
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
18 goes into 140 7 times with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 13873.77
Subtract 126 from 140 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 13873.77, and the remainder is 0.014.
