310950 divided by 12 
We want to divide 310950 by 12.

Step 1:
If we divide 3 by 12, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 12

Step 2:
12 can be fit into 31 2 times, resulting in a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 24 from 31 and we're left with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 12

Step 3:
12 goes into 70 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we take 60 away from 70, we end up with 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 12

Advancing to step 4:
When dividing 109 by 12, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 259.0
If we subtract 108 from 109, we get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 12

Moving on to step 5:
When dividing 15 by 12, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 2591.0
Deduct 12 from 15 and we're left with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 12

Going ahead to step 6:
When dividing 30 by 12, we get 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 25912.0
Subtract 24 from 30 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
The number 12 fits into 60 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 25912.5
Deduct 60 from 60 and we're left 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.

On to step 8:
12 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 25912.5
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 9:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 25912.5
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.

The final outcome is 25912.5, with a leftover of 0.0.
