307907 ÷ 12 
We want to figure out the number of times 307907 can be divided by 12.

On to step 1:
3 divided by 12 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 12

Going ahead to step 2:
The number 12 fits into 30 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 6 after subtracting 24 from 30.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 12

Moving on to step 3:
12 can be fit into 67 5 times, resulting in a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Deduct 60 from 67 and we're left with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 12

Going ahead to step 4:
79 divided by 12 is 6 with a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 256.0
Subtracting 72 from 79 leaves us with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 12

Let's proceed to step 5:
The number 12 fits into 70 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 2565.0
The remainder is 10 after subtracting 60 from 70.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 12

Step 6:
107 divided by 12 is 8 with a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 25658.0
If we subtract 96 from 107, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
If we divide 110 by 12, we get 9 and a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 25658.9
If we subtract 108 from 110, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
12 can be fit into 20 1 times, resulting in a remainder of 8.
The next digit of our result is 1. 
Result so far: 25658.91
If we take 12 away from 20, we end up 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.

Step 9:
12 can be fit into 80 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 25658.916
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.

On to step 10:
The number 12 fits into 80 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 25658.9166
Deduct 72 from 80 and we're left 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 25658.9166 with a remainder of 8e-05.
