171012 ÷ 80 
We're looking to find how many times 80 goes into 171012.

Let's proceed to step 1:
80 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 80

Advancing to step 2:
17 divided by 80 is 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 80

Let's proceed to step 3:
80 can be fit into 171 2 times, resulting in a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 160 from 171, we get 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 80

On to step 4:
110 divided by 80 is 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Deduct 80 from 110 and we're left with 30.
Append the next digit (1) from the dividend to 30 and continue with: 301 / 80

Advancing to step 5:
When dividing 301 by 80, we get 3 with a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 213.0
Deduct 240 from 301 and we're left with 61.
Append the next digit (2) from the dividend to 61 and continue with: 612 / 80

On to step 6:
80 can be fit into 612 7 times, resulting in a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 2137.0
Deduct 560 from 612 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 7:
The number 80 fits into 520 6 times, leaving a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 2137.6
If we take 480 away from 520, 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.

Step 8:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 2137.65
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.

Let's proceed to step 9:
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: 2137.65
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 10:
If we divide 0 by 80, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2137.65
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.

The quotient of the division is 2137.65, and the remainder is 0.0.
