Going ahead to step 5:
279 divided by 915 is 0 with a remainder of 279.
Write down 0 as next digit of the result. 
Result so far: 80.0
Deduct 0 from 279 and we're left with 279.
Include the next digit (2) from the dividend after 279, then repeat: 2792 / 915

Going ahead to step 6:
When dividing 2792 by 915, we get 3 with a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 803.0
Deduct 2745 from 2792 and we're left with 47.
Bring next digit (8) of the dividend behind the 47 and repeat the process: 478 / 915

Let's proceed to step 7:
915 goes into 478 0 times with a remainder of 478.
Put 0 as the next digit of the answer. 
Result so far: 8030.0
If we subtract 0 from 478, we get 478.
Bring next digit (5) of the dividend behind the 478 and repeat the process: 4785 / 915

Moving on to step 8:
915 goes into 4785 5 times with a remainder of 210.
The next digit of our result is 5. 
Result so far: 80305.0
Subtract 4575 from 4785 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 9:
When dividing 2100 by 915, we get 2 with a remainder of 270.
Record the quotient 2 as the next digit in the result. 
Result so far: 80305.2
The remainder is 270 after subtracting 1830 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 10:
If we divide 2700 by 915, we get 2 and a remainder of 870.
The number 2 becomes the next digit in our result. 
Result so far: 80305.22
If we subtract 1830 from 2700, we get 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8700, and continue the process.

Our division results in 80305.22 with a remaining 0.87.
