287539 ÷ 12 
We want to divide 287539 by 12.

On to step 1:
2 divided by 12 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 12

Let's proceed to step 2:
If we divide 28 by 12, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 4 after subtracting 24 from 28.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 12

Moving on to step 3:
47 divided by 12 is 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Deduct 36 from 47 and we're left with 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 12

On to step 4:
115 divided by 12 is 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 239.0
If we take 108 away from 115, we end up with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 12

Advancing to step 5:
12 goes into 73 6 times with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 2396.0
If we take 72 away from 73, we end up with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 12

Let's proceed to step 6:
12 can be fit into 19 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 23961.0
The remainder is 7 after subtracting 12 from 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
12 can be fit into 70 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 23961.5
If we take 60 away from 70, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
12 goes into 100 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 23961.58
The remainder is 4 after subtracting 96 from 100.
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:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 23961.583
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.

Moving on to step 10:
40 divided by 12 is 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 23961.5833
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 23961.5833 with a remainder of 4e-05.
