77 goes into 80 1 times with a remainder of 3.
The next digit of our result is 1. 
Result so far: 12615.961
Subtracting 77 from 80 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
30 divided by 77 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 12615.961
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
77 goes into 300 3 times with a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 12615.96103
Deduct 231 from 300 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 12:
77 goes into 690 8 times with a remainder of 74.
The number 8 becomes the next digit in our result. 
Result so far: 12615.961038
Subtracting 616 from 690 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 13:
If we divide 740 by 77, we get 9 and a remainder of 47.
Put 9 as the next digit of the answer. 
Result so far: 12615.9610389
The remainder is 47 after subtracting 693 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 14:
When dividing 470 by 77, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 12615.96103896
Deduct 462 from 470 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 12615.96103896, with a leftover of 8e-09.
