We look at the division of 285331 by 18 
We want to divide 285331 by 18.

Let's proceed to step 1:
18 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 18

On to step 2:
18 goes into 28 1 times with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 18 away from 28, we end up with 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 18

Step 3:
18 can be fit into 105 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 90 from 105 and we're left with 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 18

Step 4:
18 goes into 153 8 times with a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 158.0
The remainder is 9 after subtracting 144 from 153.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 18

Let's proceed to step 5:
93 divided by 18 is 5 with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 1585.0
The remainder is 3 after subtracting 90 from 93.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 18

Going ahead to step 6:
When dividing 31 by 18, we get 1 with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 15851.0
Subtract 18 from 31 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
The number 18 fits into 130 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 15851.7
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
18 goes into 40 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 15851.72
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
When dividing 40 by 18, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 15851.722
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 15851.722 with a remaining 0.0004.
