128078 divided by 20 
Our goal is to divide 128078 by 20.

Moving on to step 1:
1 divided by 20 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 20

Going ahead to step 2:
20 goes into 12 0 times with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 20

Going ahead to step 3:
20 goes into 128 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 120 from 128 to get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 20

Going ahead to step 4:
80 divided by 20 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Subtracting 80 from 80 leaves us with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 20

Step 5:
20 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 640.0
If we take 0 away from 7, we end up with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 20

Let's proceed to step 6:
The number 20 fits into 78 3 times, leaving a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 6403.0
If we subtract 60 from 78, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
20 goes into 180 9 times with a remainder of 0.
The next digit of our result is 9. 
Result so far: 6403.9
Subtract 180 from 180 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.

Moving on to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 6403.9
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.

Going ahead to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 6403.9
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.

The quotient of the division is 6403.9, and the remainder is 0.0.
