Let's divide 80071 by 20
We want to divide 80071 by 20.

Step 1:
When dividing 8 by 20, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 20

On to step 2:
20 goes into 80 4 times with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 80 from 80, we get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 20

Let's proceed to step 3:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 40.0
Deduct 0 from 0 and we're left with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 20

Step 4:
20 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 400.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 20

Moving on to step 5:
20 can be fit into 71 3 times, resulting in a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 4003.0
Subtracting 60 from 71 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 6:
If we divide 110 by 20, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 4003.5
Subtracting 100 from 110 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
100 divided by 20 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 4003.55
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.

Our division results in 4003.55 with a remaining 0.0.
