We look at the division of 345609 by 18 
Our goal is to divide 345609 by 18.

Let's proceed to step 1:
18 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 18

Let's proceed to step 2:
When dividing 34 by 18, we get 1 with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 18 away from 34, we end up with 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 18

Going ahead to step 3:
18 can be fit into 165 9 times, resulting in a remainder of 3.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 3 after subtracting 162 from 165.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 18

Moving on 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: 192.0
Deduct 36 from 36 and we're left with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 18

Advancing to step 5:
0 divided by 18 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1920.0
If we subtract 0 from 0, we get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 18

On to 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: 19200.0
If we subtract 0 from 9, we 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.

Going ahead to step 7:
When dividing 90 by 18, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 19200.5
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.

Advancing to step 8:
18 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 19200.5
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:
0 divided by 18 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 19200.5
Subtracting 0 from 0 leaves us 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.

Our division results in 19200.5 with a remaining 0.0.
