We look at the division of 77984695 by 129 
We want to figure out the number of times 77984695 can be divided by 129.

Moving on to step 1:
The number 129 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 129

Let's proceed to step 2:
When dividing 77 by 129, we get 0 with 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.
Append the next digit (9) from the dividend to 77 and continue with: 779 / 129

Going ahead to step 3:
When dividing 779 by 129, we get 6 with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 774 from 779 and we're left with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 129

On to step 4:
129 can be fit into 58 0 times, resulting in a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
Subtract 0 from 58 to get 58.
Bring next digit (4) of the dividend behind the 58 and repeat the process: 584 / 129

Step 5:
584 divided by 129 is 4 with a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 604.0
Subtract 516 from 584 to get 68.
Fetch the next digit (6) from the dividend, attach it to 68 and continue: 686 / 129

Moving on to step 6:
The number 129 fits into 686 5 times, leaving a remainder of 41.
Write down 5 as next digit of the result. 
Result so far: 6045.0
Subtracting 645 from 686 leaves us with 41.
Include the next digit (9) from the dividend after 41, then repeat: 419 / 129

Let's proceed to step 7:
The number 129 fits into 419 3 times, leaving a remainder of 32.
Put 3 as the next digit of the answer. 
Result so far: 60453.0
If we subtract 387 from 419, we get 32.
Append the next digit (5) from the dividend to 32 and continue with: 325 / 129

Step 8:
If we divide 325 by 129, we get 2 and a remainder of 67.
Use 2 as the next digit of our solution. 
Result so far: 604532.0
If we subtract 258 from 325, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 9:
When dividing 670 by 129, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 604532.5
Subtract 645 from 670 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 10:
129 goes into 250 1 times with a remainder of 121.
Put 1 as the next digit of the answer. 
Result so far: 604532.51
Subtracting 129 from 250 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

On to step 11:
The number 129 fits into 1210 9 times, leaving a remainder of 49.
Write down 9 as next digit of the result. 
Result so far: 604532.519
Subtracting 1161 from 1210 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.

On to step 12:
129 can be fit into 490 3 times, resulting in a remainder of 103.
The next digit of our result is 3. 
Result so far: 604532.5193
If we subtract 387 from 490, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

On to step 13:
When dividing 1030 by 129, we get 7 with a remainder of 127.
Write down 7 as next digit of the result. 
Result so far: 604532.51937
If we subtract 903 from 1030, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Going ahead to step 14:
129 goes into 1270 9 times with a remainder of 109.
The next digit of our result is 9. 
Result so far: 604532.519379
Deduct 1161 from 1270 and we're left with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Advancing to step 15:
If we divide 1090 by 129, we get 8 and a remainder of 58.
The next digit of our result is 8. 
Result so far: 604532.5193798
Subtracting 1032 from 1090 leaves us 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.

Let's proceed to step 16:
580 divided by 129 is 4 with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 604532.51937984
Deduct 516 from 580 and we're left 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.

The final outcome is 604532.51937984, with a leftover of 6.4e-08.
