615609 divided by 18 
We want to divide 615609 by 18.

Going ahead to step 1:
The number 18 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 18

Advancing to step 2:
The number 18 fits into 61 3 times, leaving a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 54 from 61 leaves us with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 18

Going ahead to step 3:
18 can be fit into 75 4 times, resulting in a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we take 72 away from 75, we end up with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 18

Let's proceed to step 4:
When dividing 36 by 18, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 342.0
Deduct 36 from 36 and we're left with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 18

Moving on to step 5:
If we divide 0 by 18, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3420.0
Subtract 0 from 0 to get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 18

Step 6:
The number 18 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 34200.0
Subtract 0 from 9 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
90 divided by 18 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 34200.5
Deduct 90 from 90 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
18 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 34200.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
If we divide 0 by 18, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 34200.5
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.

The final result is 34200.5 with a remainder of 0.0.
