Let's divide 286277 by 12
We're looking to find how many times 12 goes into 286277.

Going ahead to step 1:
When dividing 2 by 12, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 12

Let's proceed to step 2:
When dividing 28 by 12, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 24 away from 28, we end up with 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 12

Going ahead to step 3:
46 divided by 12 is 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtract 36 from 46 to get 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 12

Advancing to step 4:
If we divide 102 by 12, we get 8 and a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 238.0
Subtract 96 from 102 to get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 12

Let's proceed to step 5:
If we divide 67 by 12, we get 5 and a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 2385.0
If we take 60 away from 67, we end up with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 12

On to step 6:
12 goes into 77 6 times with a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 23856.0
Deduct 72 from 77 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
12 goes into 50 4 times with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 23856.4
Subtracting 48 from 50 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
12 can be fit into 20 1 times, resulting in a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 23856.41
Subtract 12 from 20 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 23856.416
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
When dividing 80 by 12, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 23856.4166
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 23856.4166 with a remainder of 8e-05.
