310316 ÷ 12 
We're looking to find how many times 12 goes into 310316.

Going ahead to step 1:
12 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 12

Step 2:
When dividing 31 by 12, we get 2 with a remainder of 7.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 7 after subtracting 24 from 31.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 12

On to step 3:
If we divide 70 by 12, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we take 60 away from 70, we end up with 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 12

Advancing to step 4:
12 goes into 103 8 times with a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 258.0
If we take 96 away from 103, we end up with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 12

Moving on to step 5:
12 can be fit into 71 5 times, resulting in a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 2585.0
Subtract 60 from 71 to get 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 12

Let's proceed to step 6:
12 goes into 116 9 times with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 25859.0
Subtract 108 from 116 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.

Moving on to step 7:
The number 12 fits into 80 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 25859.6
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.

Let's proceed to step 8:
When dividing 80 by 12, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 25859.66
The remainder is 8 after subtracting 72 from 80.
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 outcome is 25859.66, with a leftover of 0.008.
