We look at the division of 444634 by 18 
The aim is to understand the frequency of 18 in 444634.

Moving on to step 1:
If we divide 4 by 18, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 18

Step 2:
18 goes into 44 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 36 from 44, we get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 18

On to step 3:
84 divided by 18 is 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we take 72 away from 84, we end up with 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 18

Advancing to step 4:
When dividing 126 by 18, we get 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 247.0
If we subtract 126 from 126, we get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 18

On to step 5:
18 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 2470.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 18

On to step 6:
18 can be fit into 34 1 times, resulting in a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 24701.0
Subtract 18 from 34 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
160 divided by 18 is 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 24701.8
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
18 can be fit into 160 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 24701.88
Deduct 144 from 160 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.

The final result is 24701.88 with a remainder of 0.016.
