We look at the division of 129497 by 80 
We want to divide 129497 by 80.

Let's proceed to step 1:
The number 80 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 80

On to step 2:
When dividing 12 by 80, we get 0 with a remainder of 12.
The number 0 becomes the next digit in our 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

Step 3:
129 divided by 80 is 1 with a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 80 away from 129, we end up with 49.
Append the next digit (4) from the dividend to 49 and continue with: 494 / 80

Let's proceed to step 4:
If we divide 494 by 80, we get 6 and a remainder of 14.
The next digit of our result is 6. 
Result so far: 16.0
Subtracting 480 from 494 leaves us with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 80

On to step 5:
When dividing 149 by 80, we get 1 with a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 161.0
Subtract 80 from 149 to get 69.
Take the next digit (7) from the dividend and append it to 69, then repeat: 697 / 80

Let's proceed to step 6:
The number 80 fits into 697 8 times, leaving a remainder of 57.
The next digit of our result is 8. 
Result so far: 1618.0
If we subtract 640 from 697, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 7:
If we divide 570 by 80, we get 7 and a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 1618.7
If we take 560 away from 570, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
80 goes into 100 1 times with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1618.71
Subtracting 80 from 100 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
If we divide 200 by 80, we get 2 and a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 1618.712
Deduct 160 from 200 and we're left with 40.
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.
The next digit of our result is 5. 
Result so far: 1618.7125
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.

Going ahead to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1618.7125
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:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1618.7125
If we subtract 0 from 0, 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.

The final result is 1618.7125 with a remainder of 0.0.
