We're dividing 128255 by 80 
Let's see how many times 80 fits into 128255.

On to step 1:
When dividing 1 by 80, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 80

Advancing to step 2:
If we divide 12 by 80, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 80

On to step 3:
If we divide 128 by 80, we get 1 and a remainder of 48.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 80 from 128, we get 48.
Append the next digit (2) from the dividend to 48 and continue with: 482 / 80

Going ahead to step 4:
The number 80 fits into 482 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 480 from 482, we get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 80

Advancing to step 5:
The number 80 fits into 25 0 times, leaving a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 160.0
Subtract 0 from 25 to get 25.
Take the next digit (5) from the dividend and append it to 25, then repeat: 255 / 80

Going ahead to step 6:
When dividing 255 by 80, we get 3 with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 1603.0
Subtracting 240 from 255 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
The number 80 fits into 150 1 times, leaving a remainder of 70.
The next digit of our result is 1. 
Result so far: 1603.1
Deduct 80 from 150 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 8:
80 can be fit into 700 8 times, resulting in a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 1603.18
Subtract 640 from 700 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
600 divided by 80 is 7 with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 1603.187
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1603.1875
Deduct 400 from 400 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.

Moving on to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1603.1875
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.

On to step 12:
0 divided by 80 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1603.1875
Subtract 0 from 0 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.

The quotient of the division is 1603.1875, and the remainder is 0.0.
