65336308 ÷ 80 
Let's see how many times 80 fits into 65336308.

Step 1:
If we divide 6 by 80, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 80

Going ahead to step 2:
80 goes into 65 0 times with a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Include the next digit (3) from the dividend after 65, then repeat: 653 / 80

Going ahead to step 3:
653 divided by 80 is 8 with a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 640 away from 653, we end up with 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 80

Advancing to step 4:
If we divide 133 by 80, we get 1 and a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
Deduct 80 from 133 and we're left with 53.
Append the next digit (6) from the dividend to 53 and continue with: 536 / 80

Step 5:
When dividing 536 by 80, we get 6 with a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 816.0
Subtracting 480 from 536 leaves us with 56.
Append the next digit (3) from the dividend to 56 and continue with: 563 / 80

On to step 6:
80 goes into 563 7 times with a remainder of 3.
The next digit of our result is 7. 
Result so far: 8167.0
Deduct 560 from 563 and we're left with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 80

On to step 7:
80 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 81670.0
If we subtract 0 from 30, we get 30.
Grab the next digit (8) from the dividend, add it to 30, then carry on: 308 / 80

Advancing to step 8:
308 divided by 80 is 3 with a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 816703.0
Subtracting 240 from 308 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 9:
If we divide 680 by 80, we get 8 and a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 816703.8
Subtract 640 from 680 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 816703.85
If we subtract 400 from 400, 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.

Advancing to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 816703.85
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.

Let's proceed to step 12:
80 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 816703.85
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.

In conclusion, the division gives 816703.85 with a balance of 0.0.
