801710 divided by 80 
We're looking to find how many times 80 goes into 801710.

Step 1:
If we divide 8 by 80, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 80

Step 2:
If we divide 80 by 80, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 80 from 80 and we're left with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 80

Let's proceed to step 3:
1 divided by 80 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 1 to get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 80

On to step 4:
80 goes into 17 0 times with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
Deduct 0 from 17 and we're left with 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 80

On to step 5:
171 divided by 80 is 2 with a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 1002.0
If we subtract 160 from 171, we get 11.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 80

Step 6:
110 divided by 80 is 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 10021.0
Subtract 80 from 110 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
If we divide 300 by 80, we get 3 and a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 10021.3
Subtract 240 from 300 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
600 divided by 80 is 7 with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 10021.37
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
80 goes into 400 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 10021.375
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.

Let's proceed to step 10:
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: 10021.375
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 11:
0 divided by 80 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10021.375
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.

The quotient of the division is 10021.375, and the remainder is 0.0.
