We look at the division of 351159 by 18 
Let's see how many times 18 fits into 351159.

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
Subtracting 0 from 3 leaves us with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 18

Going ahead to step 2:
The number 18 fits into 35 1 times, leaving a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 18 from 35 to get 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 18

Step 3:
18 can be fit into 171 9 times, resulting in a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 19.0
The remainder is 9 after subtracting 162 from 171.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 18

Let's proceed to step 4:
18 goes into 91 5 times with a remainder of 1.
The next digit of our result is 5. 
Result so far: 195.0
Subtract 90 from 91 to get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 18

Step 5:
18 can be fit into 15 0 times, resulting in a remainder of 15.
The next digit of our result is 0. 
Result so far: 1950.0
If we subtract 0 from 15, we get 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 18

Let's proceed to step 6:
The number 18 fits into 159 8 times, leaving a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 19508.0
If we take 144 away from 159, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
When dividing 150 by 18, we get 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 19508.8
Subtracting 144 from 150 leaves us 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.

Going ahead to step 8:
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: 19508.83
If we subtract 54 from 60, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
60 divided by 18 is 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 19508.833
If we subtract 54 from 60, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 19508.833 and a remainder of 0.0006.
