We look at the division of 286509 by 18 
Our goal is to divide 286509 by 18.

Step 1:
2 divided by 18 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 18

On to step 2:
If we divide 28 by 18, we get 1 and a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 18 from 28 and we're left with 10.
Bring next digit (6) of the dividend behind the 10 and repeat the process: 106 / 18

Going ahead to step 3:
The number 18 fits into 106 5 times, leaving a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 15.0
The remainder is 16 after subtracting 90 from 106.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 18

On to step 4:
When dividing 165 by 18, we get 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 159.0
The remainder is 3 after subtracting 162 from 165.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 18

Let's proceed to step 5:
If we divide 30 by 18, we get 1 and a remainder of 12.
The next digit of our result is 1. 
Result so far: 1591.0
Subtract 18 from 30 to get 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 18

Going ahead to step 6:
When dividing 129 by 18, we get 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 15917.0
Subtract 126 from 129 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
18 goes into 30 1 times with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 15917.1
Subtract 18 from 30 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
18 can be fit into 120 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 15917.16
If we take 108 away from 120, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
When dividing 120 by 18, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 15917.166
Deduct 108 from 120 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 15917.166 and a remainder of 0.0012.
