317103 ÷ 12 
We're looking to find how many times 12 goes into 317103.

Step 1:
12 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 12

Going ahead to step 2:
31 divided by 12 is 2 with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 7 after subtracting 24 from 31.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 12

Advancing to step 3:
When dividing 77 by 12, we get 6 with a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtracting 72 from 77 leaves us with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 12

Step 4:
When dividing 51 by 12, we get 4 with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 264.0
Subtracting 48 from 51 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 12

Step 5:
12 can be fit into 30 2 times, resulting in a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 2642.0
Deduct 24 from 30 and we're left with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 12

Moving on to step 6:
12 goes into 63 5 times with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 26425.0
Subtracting 60 from 63 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.

On to 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: 26425.2
Subtracting 24 from 30 leaves us 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.

Let's proceed to step 8:
12 can be fit into 60 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 26425.25
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:
12 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 26425.25
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.

Step 10:
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: 26425.25
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.

After the division, we end up with 26425.25 and a remainder of 0.0.
