302907 divided by 12 
We want to divide 302907 by 12.

Going ahead to step 1:
When dividing 3 by 12, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 12

On to step 2:
12 can be fit into 30 2 times, resulting in a remainder of 6.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 6 after subtracting 24 from 30.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 12

On to step 3:
12 can be fit into 62 5 times, resulting in a remainder of 2.
The next digit of our result is 5. 
Result so far: 25.0
Deduct 60 from 62 and we're left with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 12

Step 4:
12 goes into 29 2 times with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 252.0
The remainder is 5 after subtracting 24 from 29.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 12

Going ahead to step 5:
12 can be fit into 50 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 2524.0
Subtracting 48 from 50 leaves us with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 12

Moving on to step 6:
12 can be fit into 27 2 times, resulting in a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 25242.0
Subtracting 24 from 27 leaves us with 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:
12 goes into 30 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 25242.2
If we take 24 away from 30, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
12 can be fit into 60 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 25242.25
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 25242.25
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 25242.25
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 25242.25, and the remainder is 0.0.
