We divide 65304584 by 80
Let's see how many times 80 fits into 65304584.

Step 1:
The number 80 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
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

Moving on to step 2:
If we divide 65 by 80, we get 0 and a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 65 after subtracting 0 from 65.
Take the next digit (3) from the dividend and append it to 65, then repeat: 653 / 80

Let's proceed to step 3:
When dividing 653 by 80, we get 8 with a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 13 after subtracting 640 from 653.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 80

Moving on to step 4:
80 can be fit into 130 1 times, resulting in a remainder of 50.
Use 1 as the next digit of our solution. 
Result so far: 81.0
If we subtract 80 from 130, we get 50.
Include the next digit (4) from the dividend after 50, then repeat: 504 / 80

Advancing to step 5:
80 can be fit into 504 6 times, resulting in a remainder of 24.
The next digit of our result is 6. 
Result so far: 816.0
The remainder is 24 after subtracting 480 from 504.
Append the next digit (5) from the dividend to 24 and continue with: 245 / 80

Step 6:
If we divide 245 by 80, we get 3 and a remainder of 5.
The next digit of our result is 3. 
Result so far: 8163.0
Subtract 240 from 245 to get 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 80

Step 7:
80 goes into 58 0 times with a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 81630.0
If we subtract 0 from 58, we get 58.
Append the next digit (4) from the dividend to 58 and continue with: 584 / 80

Advancing to step 8:
80 can be fit into 584 7 times, resulting in a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 816307.0
If we take 560 away from 584, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
The number 80 fits into 240 3 times, leaving a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 816307.3
If we subtract 240 from 240, 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.

Moving on to step 10:
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: 816307.3
Deduct 0 from 0 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.

Advancing to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 816307.3
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.

The final outcome is 816307.3, with a leftover of 0.0.
