310530 divided by 20 
Our goal is to divide 310530 by 20.

Let's proceed to step 1:
If we divide 3 by 20, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 20

Going ahead to step 2:
The number 20 fits into 31 1 times, leaving a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 20 from 31 to get 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 20

On to step 3:
20 can be fit into 110 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 100 from 110 to get 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 20

Advancing to step 4:
When dividing 105 by 20, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 155.0
The remainder is 5 after subtracting 100 from 105.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 20

Going ahead to step 5:
20 goes into 53 2 times with a remainder of 13.
The next digit of our result is 2. 
Result so far: 1552.0
Deduct 40 from 53 and we're left with 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 20

On to step 6:
If we divide 130 by 20, we get 6 and a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 15526.0
If we subtract 120 from 130, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
If we divide 100 by 20, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 15526.5
If we take 100 away from 100, 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 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 15526.5
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.

Advancing to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15526.5
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 outcome is 15526.5, with a leftover of 0.0.
