We're dividing 320260 by 20 
Our goal is to divide 320260 by 20.

Step 1:
If we divide 3 by 20, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 20

Let's proceed to step 2:
The number 20 fits into 32 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 20 from 32 leaves us with 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 20

Step 3:
20 can be fit into 120 6 times, resulting in a remainder of 0.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 120 from 120 and we're left with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 20

Advancing to step 4:
If we divide 2 by 20, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 160.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 20

Step 5:
20 goes into 26 1 times with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1601.0
Subtracting 20 from 26 leaves us with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 20

Moving on to step 6:
The number 20 fits into 60 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 16013.0
Subtract 60 from 60 to 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.

Going ahead to step 7:
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: 16013.0
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.

Let's proceed 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: 16013.0
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.

The final outcome is 16013.0, with a leftover of 0.0.
