We look at the division of 310488 by 20 
We're looking to find how many times 20 goes into 310488.

Moving on to step 1:
20 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 20

On to step 2:
When dividing 31 by 20, we get 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 20 from 31, we get 11.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 20

Going ahead to step 3:
110 divided by 20 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 100 from 110 leaves us with 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 20

Let's proceed to step 4:
104 divided by 20 is 5 with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 155.0
If we subtract 100 from 104, we get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 20

On to step 5:
48 divided by 20 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 1552.0
If we subtract 40 from 48, we get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 20

Advancing to step 6:
The number 20 fits into 88 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 15524.0
Subtract 80 from 88 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
20 goes into 80 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 15524.4
Deduct 80 from 80 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 8:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15524.4
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.

Moving on to step 9:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15524.4
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.

After the division, we end up with 15524.4 and a remainder of 0.0.
