77699919 ÷ 82 
We're looking to find how many times 82 goes into 77699919.

Let's proceed to step 1:
7 divided by 82 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 82

On to step 2:
When dividing 77 by 82, we get 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Append the next digit (6) from the dividend to 77 and continue with: 776 / 82

Advancing to step 3:
The number 82 fits into 776 9 times, leaving a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 38 after subtracting 738 from 776.
Grab the next digit (9) from the dividend, add it to 38, then carry on: 389 / 82

Step 4:
The number 82 fits into 389 4 times, leaving a remainder of 61.
Use 4 as the next digit of our solution. 
Result so far: 94.0
The remainder is 61 after subtracting 328 from 389.
Include the next digit (9) from the dividend after 61, then repeat: 619 / 82

On to step 5:
The number 82 fits into 619 7 times, leaving a remainder of 45.
The number 7 becomes the next digit in our result. 
Result so far: 947.0
If we subtract 574 from 619, we get 45.
Append the next digit (9) from the dividend to 45 and continue with: 459 / 82

Going ahead to step 6:
459 divided by 82 is 5 with a remainder of 49.
The number 5 becomes the next digit in our result. 
Result so far: 9475.0
Subtract 410 from 459 to get 49.
Bring next digit (1) of the dividend behind the 49 and repeat the process: 491 / 82

Advancing to step 7:
491 divided by 82 is 5 with a remainder of 81.
Write down 5 as next digit of the result. 
Result so far: 94755.0
Subtract 410 from 491 to get 81.
Take the next digit (9) from the dividend and append it to 81, then repeat: 819 / 82

Moving on to step 8:
819 divided by 82 is 9 with a remainder of 81.
Use 9 as the next digit of our solution. 
Result so far: 947559.0
Subtract 738 from 819 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 9:
82 goes into 810 9 times with a remainder of 72.
Put 9 as the next digit of the answer. 
Result so far: 947559.9
Subtract 738 from 810 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 10:
When dividing 720 by 82, we get 8 with a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 947559.98
Subtracting 656 from 720 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 11:
82 can be fit into 640 7 times, resulting in a remainder of 66.
The next digit of our result is 7. 
Result so far: 947559.987
If we take 574 away from 640, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 12:
When dividing 660 by 82, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 947559.9878
Deduct 656 from 660 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
82 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 947559.9878
If we take 0 away from 40, we end up with 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 14:
82 can be fit into 400 4 times, resulting in a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 947559.987804
Deduct 328 from 400 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 15:
720 divided by 82 is 8 with a remainder of 64.
The next digit of our result is 8. 
Result so far: 947559.9878048
The remainder is 64 after subtracting 656 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 16:
82 can be fit into 640 7 times, resulting in a remainder of 66.
The number 7 becomes the next digit in our result. 
Result so far: 947559.98780487
Subtracting 574 from 640 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final outcome is 947559.98780487, with a leftover of 6.6e-08.
