822549 divided by 18 
The aim is to understand the frequency of 18 in 822549.

Going ahead to step 1:
When dividing 8 by 18, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 18

Let's proceed to step 2:
18 can be fit into 82 4 times, resulting in a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 72 from 82 and we're left with 10.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 18

On to step 3:
If we divide 102 by 18, we get 5 and a remainder of 12.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
If we subtract 90 from 102, we get 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 18

On to step 4:
When dividing 125 by 18, we get 6 with a remainder of 17.
Record the quotient 6 as the next digit in the result. 
Result so far: 456.0
If we subtract 108 from 125, we get 17.
Append the next digit (4) from the dividend to 17 and continue with: 174 / 18

On to step 5:
18 goes into 174 9 times with a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 4569.0
Deduct 162 from 174 and we're left with 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 18

Moving on to step 6:
18 goes into 129 7 times with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 45697.0
If we take 126 away from 129, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
18 can be fit into 30 1 times, resulting in a remainder of 12.
The next digit of our result is 1. 
Result so far: 45697.1
If we subtract 18 from 30, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
The number 18 fits into 120 6 times, leaving a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 45697.16
If we subtract 108 from 120, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
If we divide 120 by 18, we get 6 and a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 45697.166
If we take 108 away from 120, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 45697.166 with a remaining 0.0012.
