Let's divide 65371288 by 80
We want to figure out the number of times 65371288 can be divided by 80.

Going ahead to step 1:
When dividing 6 by 80, we get 0 with 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

Moving on 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
If we take 0 away from 65, we end up with 65.
Append the next digit (3) from the dividend to 65 and continue with: 653 / 80

Let's proceed to step 3:
The number 80 fits into 653 8 times, leaving a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 13 after subtracting 640 from 653.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 80

Moving on to step 4:
If we divide 137 by 80, we get 1 and a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
The remainder is 57 after subtracting 80 from 137.
Include the next digit (1) from the dividend after 57, then repeat: 571 / 80

Advancing to step 5:
571 divided by 80 is 7 with a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 817.0
If we take 560 away from 571, we end up with 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 80

Step 6:
When dividing 112 by 80, we get 1 with a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 8171.0
If we subtract 80 from 112, we get 32.
Fetch the next digit (8) from the dividend, attach it to 32 and continue: 328 / 80

Let's proceed to step 7:
80 goes into 328 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 81714.0
If we take 320 away from 328, we end up with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 80

Step 8:
When dividing 88 by 80, we get 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 817141.0
Subtracting 80 from 88 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
When dividing 80 by 80, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 817141.1
Subtracting 80 from 80 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.

Moving on to step 10:
0 divided by 80 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 817141.1
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.

Advancing to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 817141.1
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.

After the division, we end up with 817141.1 and a remainder of 0.0.
