Let's divide 416128 by 18
The aim is to understand the frequency of 18 in 416128.

On to step 1:
The number 18 fits into 4 0 times, leaving 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.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 18

Step 2:
41 divided by 18 is 2 with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 36 from 41, we get 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 18

Advancing to step 3:
18 can be fit into 56 3 times, resulting in a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Deduct 54 from 56 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 18

Going ahead to step 4:
21 divided by 18 is 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 231.0
Subtract 18 from 21 to get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 18

Going ahead to step 5:
18 goes into 32 1 times with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 2311.0
Deduct 18 from 32 and we're left with 14.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 18

On to step 6:
18 goes into 148 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 23118.0
If we subtract 144 from 148, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
The number 18 fits into 40 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 23118.2
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
40 divided by 18 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 23118.22
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 23118.22 and a remainder of 0.004.
