311620 ÷ 12 
We want to figure out the number of times 311620 can be divided by 12.

Moving 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
Subtract 0 from 3 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 12

Moving on to step 2:
The number 12 fits into 31 2 times, leaving a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 24 from 31, we get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 12

Let's proceed to step 3:
When dividing 71 by 12, we get 5 with a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 25.0
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 4:
12 can be fit into 116 9 times, resulting in a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 259.0
If we take 108 away from 116, we end up with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 12

Moving on to step 5:
12 can be fit into 82 6 times, resulting in a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 2596.0
Subtract 72 from 82 to get 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 12

Advancing to step 6:
12 can be fit into 100 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 25968.0
Deduct 96 from 100 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
40 divided by 12 is 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 25968.3
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
If we divide 40 by 12, we get 3 and a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 25968.33
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 25968.33 with a balance of 0.004.
