319865 ÷ 20 
Our goal is to divide 319865 by 20.

On to step 1:
3 divided by 20 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 20

Moving on to step 2:
When dividing 31 by 20, we get 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 20 from 31 to get 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 20

Going ahead to step 3:
If we divide 119 by 20, we get 5 and a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 15.0
The remainder is 19 after subtracting 100 from 119.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 20

Going ahead to step 4:
The number 20 fits into 198 9 times, leaving a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 159.0
Subtract 180 from 198 to get 18.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 20

Step 5:
20 goes into 186 9 times with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 1599.0
The remainder is 6 after subtracting 180 from 186.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 20

Advancing to step 6:
The number 20 fits into 65 3 times, leaving a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 15993.0
Subtracting 60 from 65 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
The number 20 fits into 50 2 times, leaving a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 15993.2
If we subtract 40 from 50, 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.

Moving on to step 8:
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: 15993.25
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.

Let's proceed to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15993.25
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.

Step 10:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15993.25
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.

The final outcome is 15993.25, with a leftover of 0.0.
