80319 ÷ 20 
We want to figure out the number of times 80319 can be divided by 20.

Let's proceed to step 1:
When dividing 8 by 20, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 20

Let's proceed to step 2:
If we divide 80 by 20, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 80 from 80 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 20

Advancing to step 3:
When dividing 3 by 20, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 40.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 20

On to step 4:
When dividing 31 by 20, we get 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 401.0
Subtract 20 from 31 to get 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 20

Advancing to step 5:
20 can be fit into 119 5 times, resulting in a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 4015.0
If we subtract 100 from 119, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 6:
If we divide 190 by 20, we get 9 and a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 4015.9
If we subtract 180 from 190, 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.

Going ahead to step 7:
The number 20 fits into 100 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 4015.95
Subtracting 100 from 100 leaves us 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:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4015.95
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4015.95
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 4015.95 with a balance of 0.0.
