We look at the division of 339222 by 18 
Our goal is to divide 339222 by 18.

Moving on to step 1:
3 divided by 18 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 18

Step 2:
18 can be fit into 33 1 times, resulting in a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 15 after subtracting 18 from 33.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 18

Moving on to step 3:
When dividing 159 by 18, we get 8 with a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Deduct 144 from 159 and we're left with 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 18

Step 4:
18 can be fit into 152 8 times, resulting in a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 188.0
The remainder is 8 after subtracting 144 from 152.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 18

Step 5:
When dividing 82 by 18, we get 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 1884.0
Deduct 72 from 82 and we're left with 10.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 18

Moving on to step 6:
18 goes into 102 5 times with a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 18845.0
The remainder is 12 after subtracting 90 from 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
If we divide 120 by 18, we get 6 and a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 18845.6
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.

Going ahead to step 8:
If we divide 120 by 18, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 18845.66
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.

The quotient of the division is 18845.66, and the remainder is 0.012.
