Let's divide 171015 by 80
Let's see how many times 80 fits into 171015.

Going ahead to step 1:
80 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 80

On to step 2:
If we divide 17 by 80, we get 0 and a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 80

Step 3:
80 can be fit into 171 2 times, resulting in a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 160 from 171 to get 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 80

Going ahead to step 4:
80 can be fit into 110 1 times, resulting in a remainder of 30.
The next digit of our result is 1. 
Result so far: 21.0
Subtract 80 from 110 to get 30.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 80

Step 5:
When dividing 301 by 80, we get 3 with a remainder of 61.
Write down 3 as next digit of the result. 
Result so far: 213.0
If we subtract 240 from 301, we get 61.
Include the next digit (5) from the dividend after 61, then repeat: 615 / 80

Going ahead to step 6:
The number 80 fits into 615 7 times, leaving a remainder of 55.
The number 7 becomes the next digit in our result. 
Result so far: 2137.0
Subtract 560 from 615 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 7:
80 goes into 550 6 times with a remainder of 70.
Write down 6 as next digit of the result. 
Result so far: 2137.6
Deduct 480 from 550 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.

Let's proceed to step 8:
700 divided by 80 is 8 with a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 2137.68
Deduct 640 from 700 and we're left with 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:
When dividing 600 by 80, we get 7 with a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 2137.687
If we take 560 away from 600, 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.

Advancing to step 10:
400 divided by 80 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 2137.6875
Subtracting 400 from 400 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 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2137.6875
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.

Step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2137.6875
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.

In conclusion, the division gives 2137.6875 with a balance of 0.0.
