77878 divided by 82 
We're looking to find how many times 82 goes into 77878.

Step 1:
When dividing 7 by 82, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 82

Moving on to step 2:
The number 82 fits into 77 0 times, leaving a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Include the next digit (8) from the dividend after 77, then repeat: 778 / 82

Going ahead to step 3:
82 goes into 778 9 times with a remainder of 40.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 738 from 778 leaves us with 40.
Include the next digit (7) from the dividend after 40, then repeat: 407 / 82

On to step 4:
407 divided by 82 is 4 with a remainder of 79.
Put 4 as the next digit of the answer. 
Result so far: 94.0
Subtracting 328 from 407 leaves us with 79.
Bring next digit (8) of the dividend behind the 79 and repeat the process: 798 / 82

Moving on to step 5:
The number 82 fits into 798 9 times, leaving a remainder of 60.
The next digit of our result is 9. 
Result so far: 949.0
Deduct 738 from 798 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 6:
When dividing 600 by 82, we get 7 with a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 949.7
If we take 574 away from 600, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 7:
82 can be fit into 260 3 times, resulting in a remainder of 14.
The next digit of our result is 3. 
Result so far: 949.73
If we take 246 away from 260, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
The number 82 fits into 140 1 times, leaving a remainder of 58.
Record the quotient 1 as the next digit in the result. 
Result so far: 949.731
The remainder is 58 after subtracting 82 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 9:
If we divide 580 by 82, we get 7 and a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 949.7317
If we subtract 574 from 580, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
When dividing 60 by 82, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 949.7317
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
The number 82 fits into 600 7 times, leaving a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 949.731707
If we take 574 away from 600, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 12:
82 goes into 260 3 times with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 949.7317073
Deduct 246 from 260 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 13:
140 divided by 82 is 1 with a remainder of 58.
Record the quotient 1 as the next digit in the result. 
Result so far: 949.73170731
Deduct 82 from 140 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final outcome is 949.73170731, with a leftover of 5.8e-08.
