The next digit of our result is 7. 
Result so far: 2147.607
Subtract 553 from 600 to get 47.
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 10:
If we divide 470 by 79, we get 5 and a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 2147.6075
The remainder is 75 after subtracting 395 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 11:
The number 79 fits into 750 9 times, leaving a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 2147.60759
Deduct 711 from 750 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 12:
When dividing 390 by 79, we get 4 with a remainder of 74.
The next digit of our result is 4. 
Result so far: 2147.607594
Subtracting 316 from 390 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.

On to step 13:
The number 79 fits into 740 9 times, leaving a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 2147.6075949
If we subtract 711 from 740, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 14:
When dividing 290 by 79, we get 3 with a remainder of 53.
The number 3 becomes the next digit in our result. 
Result so far: 2147.60759493
If we take 237 away from 290, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Our division results in 2147.60759493 with a remaining 5.3e-08.
