We're dividing 139097 by 80 
Let's see how many times 80 fits into 139097.

On to step 1:
If we divide 1 by 80, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 80

On to step 2:
The number 80 fits into 13 0 times, leaving a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 80

Let's proceed to step 3:
When dividing 139 by 80, we get 1 with a remainder of 59.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 80 from 139, we get 59.
Fetch the next digit (0) from the dividend, attach it to 59 and continue: 590 / 80

Advancing to step 4:
If we divide 590 by 80, we get 7 and a remainder of 30.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtracting 560 from 590 leaves us with 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 80

Step 5:
If we divide 309 by 80, we get 3 and a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 173.0
The remainder is 69 after subtracting 240 from 309.
Grab the next digit (7) from the dividend, add it to 69, then carry on: 697 / 80

Moving on to step 6:
697 divided by 80 is 8 with a remainder of 57.
Write down 8 as next digit of the result. 
Result so far: 1738.0
Subtracting 640 from 697 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 7:
The number 80 fits into 570 7 times, leaving a remainder of 10.
The next digit of our result is 7. 
Result so far: 1738.7
Subtracting 560 from 570 leaves us 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:
If we divide 100 by 80, we get 1 and a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1738.71
Deduct 80 from 100 and we're left 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.

Let's proceed to step 9:
If we divide 200 by 80, we get 2 and a remainder of 40.
The next digit of our result is 2. 
Result so far: 1738.712
If we take 160 away from 200, we end up 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.

Let's proceed to step 10:
400 divided by 80 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1738.7125
If we take 400 away from 400, 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.

On to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1738.7125
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.

On to step 12:
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: 1738.7125
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.

In conclusion, the division gives 1738.7125 with a balance of 0.0.
