We're dividing 499275 by 18 
The aim is to understand the frequency of 18 in 499275.

Moving on to step 1:
When dividing 4 by 18, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 18

Step 2:
18 can be fit into 49 2 times, resulting in a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 36 from 49 and we're left with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 18

On to step 3:
The number 18 fits into 139 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 27.0
Deduct 126 from 139 and we're left with 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 18

On to step 4:
The number 18 fits into 132 7 times, leaving a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 277.0
The remainder is 6 after subtracting 126 from 132.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 18

Moving on to step 5:
When dividing 67 by 18, we get 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 2773.0
Deduct 54 from 67 and we're left with 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 18

On to step 6:
18 goes into 135 7 times with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 27737.0
Subtract 126 from 135 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
If we divide 90 by 18, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 27737.5
Subtract 90 from 90 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.

Advancing to step 8:
If we divide 0 by 18, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 27737.5
Subtracting 0 from 0 leaves us 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.

Moving on to step 9:
0 divided by 18 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 27737.5
Subtracting 0 from 0 leaves us 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.

The final result is 27737.5 with a remainder of 0.0.
