65991716 ÷ 791 
We want to figure out the number of times 65991716 can be divided by 791.

On to step 1:
791 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
Deduct 0 from 6 and we're left with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 791

Step 2:
When dividing 65 by 791, we get 0 with a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Take the next digit (9) from the dividend and append it to 65, then repeat: 659 / 791

Step 3:
659 divided by 791 is 0 with a remainder of 659.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 659 after subtracting 0 from 659.
Grab the next digit (9) from the dividend, add it to 659, then carry on: 6599 / 791

Advancing to step 4:
If we divide 6599 by 791, we get 8 and a remainder of 271.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 6328 from 6599 to get 271.
Append the next digit (1) from the dividend to 271 and continue with: 2711 / 791

On to step 5:
When dividing 2711 by 791, we get 3 with a remainder of 338.
Use 3 as the next digit of our solution. 
Result so far: 83.0
If we subtract 2373 from 2711, we get 338.
Grab the next digit (7) from the dividend, add it to 338, then carry on: 3387 / 791

Moving on to step 6:
3387 divided by 791 is 4 with a remainder of 223.
The next digit of our result is 4. 
Result so far: 834.0
The remainder is 223 after subtracting 3164 from 3387.
Include the next digit (1) from the dividend after 223, then repeat: 2231 / 791

Let's proceed to step 7:
791 goes into 2231 2 times with a remainder of 649.
Write down 2 as next digit of the result. 
Result so far: 8342.0
If we subtract 1582 from 2231, we get 649.
Fetch the next digit (6) from the dividend, attach it to 649 and continue: 6496 / 791

Moving on to step 8:
When dividing 6496 by 791, we get 8 with a remainder of 168.
The next digit of our result is 8. 
Result so far: 83428.0
Deduct 6328 from 6496 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 9:
1680 divided by 791 is 2 with a remainder of 98.
The number 2 becomes the next digit in our result. 
Result so far: 83428.2
Subtracting 1582 from 1680 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 10:
If we divide 980 by 791, we get 1 and a remainder of 189.
Record the quotient 1 as the next digit in the result. 
Result so far: 83428.21
Subtracting 791 from 980 leaves us with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

On to step 11:
791 goes into 1890 2 times with a remainder of 308.
Write down 2 as next digit of the result. 
Result so far: 83428.212
If we take 1582 away from 1890, we end up with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Let's proceed to step 12:
If we divide 3080 by 791, we get 3 and a remainder of 707.
Use 3 as the next digit of our solution. 
Result so far: 83428.2123
Subtracting 2373 from 3080 leaves us with 707.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7070, and continue the process.

Moving on to step 13:
791 can be fit into 7070 8 times, resulting in a remainder of 742.
The next digit of our result is 8. 
Result so far: 83428.21238
Deduct 6328 from 7070 and we're left with 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

Advancing to step 14:
7420 divided by 791 is 9 with a remainder of 301.
Use 9 as the next digit of our solution. 
Result so far: 83428.212389
Subtract 7119 from 7420 to get 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

On to step 15:
If we divide 3010 by 791, we get 3 and a remainder of 637.
Put 3 as the next digit of the answer. 
Result so far: 83428.2123893
The remainder is 637 after subtracting 2373 from 3010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

Let's proceed to step 16:
791 goes into 6370 8 times with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 83428.21238938
The remainder is 42 after subtracting 6328 from 6370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The quotient of the division is 83428.21238938, and the remainder is 4.2e-08.
