609669 ÷ 18 
Let's see how many times 18 fits into 609669.

Going ahead to step 1:
6 divided by 18 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 18

Moving on to step 2:
The number 18 fits into 60 3 times, leaving a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 54 from 60 and we're left with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 18

Moving on to step 3:
18 can be fit into 69 3 times, resulting in a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
The remainder is 15 after subtracting 54 from 69.
Include the next digit (6) from the dividend after 15, then repeat: 156 / 18

On to step 4:
If we divide 156 by 18, we get 8 and a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 338.0
Subtracting 144 from 156 leaves us with 12.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 18

Going ahead to step 5:
126 divided by 18 is 7 with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 3387.0
Subtract 126 from 126 to get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 18

On to step 6:
18 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 33870.0
If we take 0 away from 9, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
The number 18 fits into 90 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 33870.5
Subtract 90 from 90 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
18 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 33870.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
The number 18 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 33870.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 33870.5 with a remaining 0.0.
