We look at the division of 779749 by 86 
We're looking to find how many times 86 goes into 779749.

Step 1:
If we divide 7 by 86, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 86

On to step 2:
If we divide 77 by 86, we get 0 and a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Include the next digit (9) from the dividend after 77, then repeat: 779 / 86

Moving on to step 3:
779 divided by 86 is 9 with a remainder of 5.
The next digit of our result is 9. 
Result so far: 9.0
If we take 774 away from 779, we end up with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 86

Step 4:
86 goes into 57 0 times with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 90.0
Subtract 0 from 57 to get 57.
Bring next digit (4) of the dividend behind the 57 and repeat the process: 574 / 86

On to step 5:
86 goes into 574 6 times with a remainder of 58.
Put 6 as the next digit of the answer. 
Result so far: 906.0
If we take 516 away from 574, we end up with 58.
Take the next digit (9) from the dividend and append it to 58, then repeat: 589 / 86

Going ahead to step 6:
If we divide 589 by 86, we get 6 and a remainder of 73.
Record the quotient 6 as the next digit in the result. 
Result so far: 9066.0
Subtract 516 from 589 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 7:
86 goes into 730 8 times with a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 9066.8
Subtract 688 from 730 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 8:
86 goes into 420 4 times with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 9066.84
Subtracting 344 from 420 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 9:
If we divide 760 by 86, we get 8 and a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 9066.848
Subtracting 688 from 760 leaves us 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.

Step 10:
If we divide 720 by 86, we get 8 and a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 9066.8488
Deduct 688 from 720 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 9066.8488 with a balance of 0.00032.
