We divide 129247 by 80
Our goal is to divide 129247 by 80.

Going ahead to step 1:
80 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 80

Moving on to step 2:
When dividing 12 by 80, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 80

Let's proceed to step 3:
When dividing 129 by 80, we get 1 with a remainder of 49.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 80 from 129, we get 49.
Include the next digit (2) from the dividend after 49, then repeat: 492 / 80

Step 4:
The number 80 fits into 492 6 times, leaving a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtract 480 from 492 to get 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 80

Going ahead to step 5:
When dividing 124 by 80, we get 1 with a remainder of 44.
Write down 1 as next digit of the result. 
Result so far: 161.0
The remainder is 44 after subtracting 80 from 124.
Append the next digit (7) from the dividend to 44 and continue with: 447 / 80

Advancing to step 6:
If we divide 447 by 80, we get 5 and a remainder of 47.
Record the quotient 5 as the next digit in the result. 
Result so far: 1615.0
Deduct 400 from 447 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 7:
470 divided by 80 is 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 1615.5
If we subtract 400 from 470, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 8:
If we divide 700 by 80, we get 8 and a remainder of 60.
The next digit of our result is 8. 
Result so far: 1615.58
The remainder is 60 after subtracting 640 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
80 goes into 600 7 times with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 1615.587
Subtract 560 from 600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1615.5875
The remainder is 0 after subtracting 400 from 400.
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 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1615.5875
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.

Advancing to step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1615.5875
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 1615.5875, and the remainder is 0.0.
