We divide 312083 by 20
We want to divide 312083 by 20.

Let's proceed to step 1:
When dividing 3 by 20, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 20

On to step 2:
20 can be fit into 31 1 times, resulting in a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 20 from 31 to get 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 20

Going ahead to step 3:
The number 20 fits into 112 5 times, leaving a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 100 away from 112, we end up with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 20

Moving on to step 4:
When dividing 120 by 20, we get 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 156.0
The remainder is 0 after subtracting 120 from 120.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 20

Let's proceed to step 5:
If we divide 8 by 20, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 1560.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 20

Moving on to step 6:
20 can be fit into 83 4 times, resulting in a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 15604.0
The remainder is 3 after subtracting 80 from 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
When dividing 30 by 20, we get 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 15604.1
The remainder is 10 after subtracting 20 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
100 divided by 20 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 15604.15
If we subtract 100 from 100, 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.

Step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 15604.15
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.

Advancing to step 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 15604.15
Deduct 0 from 0 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.

The final result is 15604.15 with a remainder of 0.0.
