We look at the division of 286851 by 18 
We're looking to find how many times 18 goes into 286851.

Going ahead to step 1:
If we divide 2 by 18, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 18

Moving 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 (6) from the dividend, add it to 10, then carry on: 106 / 18

On to step 3:
The number 18 fits into 106 5 times, leaving a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 90 from 106 and we're left with 16.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 18

Advancing to step 4:
The number 18 fits into 168 9 times, leaving a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 159.0
Deduct 162 from 168 and we're left with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 18

Moving on to step 5:
When dividing 65 by 18, we get 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 1593.0
Deduct 54 from 65 and we're left with 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 18

Let's proceed to step 6:
111 divided by 18 is 6 with a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 15936.0
If we subtract 108 from 111, we 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.

Advancing to step 7:
When dividing 30 by 18, we get 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 15936.1
The remainder is 12 after subtracting 18 from 30.
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:
The number 18 fits into 120 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 15936.16
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.

On to step 9:
The number 18 fits into 120 6 times, leaving a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 15936.166
Subtract 108 from 120 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.

In conclusion, the division gives 15936.166 with a balance of 0.0012.
