Let's divide 475579 by 18
The aim is to understand the frequency of 18 in 475579.

Advancing to step 1:
4 divided by 18 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 18

Going ahead to step 2:
18 can be fit into 47 2 times, resulting in a remainder of 11.
The next digit of our result is 2. 
Result so far: 2.0
If we take 36 away from 47, we end up with 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 18

Step 3:
18 goes into 115 6 times with a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
The remainder is 7 after subtracting 108 from 115.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 18

Step 4:
The number 18 fits into 75 4 times, leaving a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 264.0
If we take 72 away from 75, we end up with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 18

Step 5:
37 divided by 18 is 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2642.0
Subtracting 36 from 37 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 18

Step 6:
If we divide 19 by 18, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 26421.0
Subtract 18 from 19 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
If we divide 10 by 18, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 26421.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
The number 18 fits into 100 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 26421.05
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
When dividing 100 by 18, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 26421.055
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 26421.055 with a remaining 0.001.
