65892912 ÷ 80 
Our goal is to divide 65892912 by 80.

Let's proceed to step 1:
80 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 80

Let's proceed to step 2:
If we divide 65 by 80, we get 0 and a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Grab the next digit (8) from the dividend, add it to 65, then carry on: 658 / 80

Let's proceed to step 3:
80 goes into 658 8 times with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 640 from 658 to get 18.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 80

Let's proceed to step 4:
189 divided by 80 is 2 with a remainder of 29.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
Deduct 160 from 189 and we're left with 29.
Bring next digit (2) of the dividend behind the 29 and repeat the process: 292 / 80

On to step 5:
When dividing 292 by 80, we get 3 with a remainder of 52.
The number 3 becomes the next digit in our result. 
Result so far: 823.0
Subtract 240 from 292 to get 52.
Grab the next digit (9) from the dividend, add it to 52, then carry on: 529 / 80

Advancing to step 6:
If we divide 529 by 80, we get 6 and a remainder of 49.
The number 6 becomes the next digit in our result. 
Result so far: 8236.0
Subtracting 480 from 529 leaves us with 49.
Fetch the next digit (1) from the dividend, attach it to 49 and continue: 491 / 80

Let's proceed to step 7:
If we divide 491 by 80, we get 6 and a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 82366.0
Subtract 480 from 491 to get 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 80

Step 8:
When dividing 112 by 80, we get 1 with a remainder of 32.
The next digit of our result is 1. 
Result so far: 823661.0
Subtract 80 from 112 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
320 divided by 80 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 823661.4
If we take 320 away from 320, we end up 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.

On to step 10:
0 divided by 80 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 823661.4
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.

Step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 823661.4
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.

The quotient of the division is 823661.4, and the remainder is 0.0.
