We're dividing 596409 by 18 
We're looking to find how many times 18 goes into 596409.

Advancing to step 1:
18 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 18

Let's proceed to step 2:
The number 18 fits into 59 3 times, leaving a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 54 from 59, we get 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 18

On to step 3:
When dividing 56 by 18, we get 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 33.0
Subtract 54 from 56 to get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 18

Step 4:
18 goes into 24 1 times with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 331.0
If we take 18 away from 24, we end up with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 18

Going ahead to step 5:
60 divided by 18 is 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 3313.0
Subtract 54 from 60 to get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 18

Going ahead to step 6:
The number 18 fits into 69 3 times, leaving a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 33133.0
Subtract 54 from 69 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
The number 18 fits into 150 8 times, leaving a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 33133.8
Deduct 144 from 150 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
The number 18 fits into 60 3 times, leaving a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 33133.83
If we take 54 away from 60, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
The number 18 fits into 60 3 times, leaving a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 33133.833
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 33133.833, and the remainder is 0.0006.
