We're dividing 226175 by 18 
The aim is to understand the frequency of 18 in 226175.

Moving on to step 1:
18 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 18

Going ahead to step 2:
18 goes into 22 1 times with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 18 away from 22, we end up with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 18

Let's proceed to step 3:
46 divided by 18 is 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 36 away from 46, we end up with 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 18

Moving on to step 4:
18 can be fit into 101 5 times, resulting in a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
Subtract 90 from 101 to get 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 18

Step 5:
18 can be fit into 117 6 times, resulting in a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 1256.0
Deduct 108 from 117 and we're left with 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 18

Moving on to step 6:
95 divided by 18 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 12565.0
Subtract 90 from 95 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
18 goes into 50 2 times with a remainder of 14.
The next digit of our result is 2. 
Result so far: 12565.2
The remainder is 14 after subtracting 36 from 50.
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 can be fit into 140 7 times, resulting in a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 12565.27
If we subtract 126 from 140, 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.

Step 9:
The number 18 fits into 140 7 times, leaving a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 12565.277
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 12565.277, and the remainder is 0.0014.
