71606329 divided by 80 
We want to divide 71606329 by 80.

Going ahead to step 1:
7 divided by 80 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 80

Going ahead to step 2:
When dividing 71 by 80, we get 0 with a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Include the next digit (6) from the dividend after 71, then repeat: 716 / 80

Step 3:
80 can be fit into 716 8 times, resulting in a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 76 after subtracting 640 from 716.
Bring next digit (0) of the dividend behind the 76 and repeat the process: 760 / 80

Let's proceed to step 4:
If we divide 760 by 80, we get 9 and a remainder of 40.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
Deduct 720 from 760 and we're left with 40.
Bring next digit (6) of the dividend behind the 40 and repeat the process: 406 / 80

Advancing to step 5:
80 goes into 406 5 times with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 895.0
Subtracting 400 from 406 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 80

Advancing to step 6:
80 can be fit into 63 0 times, resulting in a remainder of 63.
The next digit of our result is 0. 
Result so far: 8950.0
If we take 0 away from 63, we end up with 63.
Fetch the next digit (2) from the dividend, attach it to 63 and continue: 632 / 80

Advancing to step 7:
If we divide 632 by 80, we get 7 and a remainder of 72.
Record the quotient 7 as the next digit in the result. 
Result so far: 89507.0
Subtracting 560 from 632 leaves us with 72.
Append the next digit (9) from the dividend to 72 and continue with: 729 / 80

Moving on to step 8:
The number 80 fits into 729 9 times, leaving a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 895079.0
Subtracting 720 from 729 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
80 can be fit into 90 1 times, resulting in a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 895079.1
If we take 80 away from 90, 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.

On to step 10:
100 divided by 80 is 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 895079.11
If we subtract 80 from 100, we 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.

Our division results in 895079.11 with a remaining 0.02.
