77809 ÷ 99 
We're looking to find how many times 99 goes into 77809.

Advancing to step 1:
99 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 99

Step 2:
If we divide 77 by 99, we get 0 and a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Include the next digit (8) from the dividend after 77, then repeat: 778 / 99

Advancing to step 3:
99 goes into 778 7 times with a remainder of 85.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 693 from 778 to get 85.
Grab the next digit (0) from the dividend, add it to 85, then carry on: 850 / 99

Let's proceed to step 4:
If we divide 850 by 99, we get 8 and a remainder of 58.
Write down 8 as next digit of the result. 
Result so far: 78.0
The remainder is 58 after subtracting 792 from 850.
Grab the next digit (9) from the dividend, add it to 58, then carry on: 589 / 99

Let's proceed to step 5:
The number 99 fits into 589 5 times, leaving a remainder of 94.
The next digit of our result is 5. 
Result so far: 785.0
If we take 495 away from 589, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 6:
940 divided by 99 is 9 with a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 785.9
Subtracting 891 from 940 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 7:
490 divided by 99 is 4 with a remainder of 94.
Record the quotient 4 as the next digit in the result. 
Result so far: 785.94
The remainder is 94 after subtracting 396 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 8:
The number 99 fits into 940 9 times, leaving a remainder of 49.
Use 9 as the next digit of our solution. 
Result so far: 785.949
Deduct 891 from 940 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 9:
490 divided by 99 is 4 with a remainder of 94.
The number 4 becomes the next digit in our result. 
Result so far: 785.9494
If we subtract 396 from 490, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 10:
99 can be fit into 940 9 times, resulting in a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 785.94949
Subtracting 891 from 940 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 11:
99 can be fit into 490 4 times, resulting in a remainder of 94.
Write down 4 as next digit of the result. 
Result so far: 785.949494
The remainder is 94 after subtracting 396 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 12:
When dividing 940 by 99, we get 9 with a remainder of 49.
Write down 9 as next digit of the result. 
Result so far: 785.9494949
If we subtract 891 from 940, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 13:
If we divide 490 by 99, we get 4 and a remainder of 94.
Use 4 as the next digit of our solution. 
Result so far: 785.94949494
If we take 396 away from 490, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

In conclusion, the division gives 785.94949494 with a balance of 9.4e-08.
