65033871 ÷ 80 
We want to divide 65033871 by 80.

On to step 1:
80 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 80

Going ahead to step 2:
80 can be fit into 65 0 times, resulting in a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Fetch the next digit (0) from the dividend, attach it to 65 and continue: 650 / 80

Step 3:
650 divided by 80 is 8 with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 10 after subtracting 640 from 650.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 80

Advancing to step 4:
The number 80 fits into 103 1 times, leaving a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 81.0
The remainder is 23 after subtracting 80 from 103.
Take the next digit (3) from the dividend and append it to 23, then repeat: 233 / 80

Advancing to step 5:
233 divided by 80 is 2 with a remainder of 73.
The number 2 becomes the next digit in our result. 
Result so far: 812.0
Subtract 160 from 233 to get 73.
Include the next digit (8) from the dividend after 73, then repeat: 738 / 80

Moving on to step 6:
80 can be fit into 738 9 times, resulting in a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 8129.0
Deduct 720 from 738 and we're left with 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 80

Going ahead to step 7:
187 divided by 80 is 2 with a remainder of 27.
The next digit of our result is 2. 
Result so far: 81292.0
Deduct 160 from 187 and we're left with 27.
Grab the next digit (1) from the dividend, add it to 27, then carry on: 271 / 80

Advancing to step 8:
When dividing 271 by 80, we get 3 with a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 812923.0
Subtracting 240 from 271 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 9:
80 goes into 310 3 times with a remainder of 70.
The number 3 becomes the next digit in our result. 
Result so far: 812923.3
If we subtract 240 from 310, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 10:
700 divided by 80 is 8 with a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 812923.38
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.

Step 11:
The number 80 fits into 600 7 times, leaving a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 812923.387
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.

Let's proceed to step 12:
400 divided by 80 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 812923.3875
Deduct 400 from 400 and we're left 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 13:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 812923.3875
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.

Let's proceed to step 14:
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: 812923.3875
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.

Our division results in 812923.3875 with a remaining 0.0.
