311680 divided by 20 
Let's see how many times 20 fits into 311680.

Going ahead to step 1:
20 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 20

Moving on to step 2:
The number 20 fits into 31 1 times, leaving a remainder of 11.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 20 from 31 and we're left with 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 20

Let's proceed to step 3:
111 divided by 20 is 5 with a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 100 from 111 to get 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 20

Going ahead to step 4:
If we divide 116 by 20, we get 5 and a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 155.0
If we subtract 100 from 116, we get 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 20

Step 5:
If we divide 168 by 20, we get 8 and a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 1558.0
Subtract 160 from 168 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 20

Moving on to step 6:
When dividing 80 by 20, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 15584.0
If we subtract 80 from 80, 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.

Let's proceed to step 7:
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: 15584.0
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.

Going ahead to step 8:
20 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: 15584.0
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 15584.0 with a remainder of 0.0.
