We divide 22273 by 18
The aim is to understand the frequency of 18 in 22273.

Advancing to step 1:
18 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 18

Going ahead to step 2:
18 can be fit into 22 1 times, resulting in a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 18 away from 22, we end up with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 18

On to step 3:
18 can be fit into 42 2 times, resulting in a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 36 from 42 leaves us with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 18

Step 4:
67 divided by 18 is 3 with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 123.0
Deduct 54 from 67 and we're left with 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 18

Let's proceed to step 5:
When dividing 133 by 18, we get 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 1237.0
Deduct 126 from 133 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 6:
18 can be fit into 70 3 times, resulting in a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 1237.3
The remainder is 16 after subtracting 54 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
The number 18 fits into 160 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 1237.38
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.

Moving on to step 8:
When dividing 160 by 18, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 1237.388
If we subtract 144 from 160, we 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.

After the division, we end up with 1237.388 and a remainder of 0.0016.
