171761 ÷ 80 
We're looking to find how many times 80 goes into 171761.

Going ahead to step 1:
If we divide 1 by 80, we get 0 and 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.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 80

Advancing to step 2:
When dividing 17 by 80, we get 0 with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 80

Going ahead to step 3:
171 divided by 80 is 2 with 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.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 80

On to step 4:
80 goes into 117 1 times with a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtracting 80 from 117 leaves us with 37.
Include the next digit (6) from the dividend after 37, then repeat: 376 / 80

Let's proceed to step 5:
80 can be fit into 376 4 times, resulting in a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 214.0
If we take 320 away from 376, we end up with 56.
Grab the next digit (1) from the dividend, add it to 56, then carry on: 561 / 80

Let's proceed to step 6:
80 can be fit into 561 7 times, resulting in a remainder of 1.
The next digit of our result is 7. 
Result so far: 2147.0
If we subtract 560 from 561, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
If we divide 10 by 80, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 2147.0
If we take 0 away from 10, 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.

Let's proceed to step 8:
If we divide 100 by 80, we get 1 and a remainder of 20.
The next digit of our result is 1. 
Result so far: 2147.01
Subtract 80 from 100 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
If we divide 200 by 80, we get 2 and a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 2147.012
Subtracting 160 from 200 leaves us 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.
The number 5 becomes the next digit in our result. 
Result so far: 2147.0125
Subtract 400 from 400 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.

On to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2147.0125
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.

Moving on to step 12:
0 divided by 80 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2147.0125
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.

Our division results in 2147.0125 with a remaining 0.0.
