Write down 5 as next digit of the result. 
Result so far: 176855.0
If we subtract 2465 from 2497, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
493 can be fit into 320 0 times, resulting in a remainder of 320.
The next digit of our result is 0. 
Result so far: 176855.0
Deduct 0 from 320 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 10:
The number 493 fits into 3200 6 times, leaving a remainder of 242.
The next digit of our result is 6. 
Result so far: 176855.06
The remainder is 242 after subtracting 2958 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

On to step 11:
2420 divided by 493 is 4 with a remainder of 448.
The next digit of our result is 4. 
Result so far: 176855.064
Subtract 1972 from 2420 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Let's proceed to step 12:
If we divide 4480 by 493, we get 9 and a remainder of 43.
The next digit of our result is 9. 
Result so far: 176855.0649
Subtract 4437 from 4480 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 13:
If we divide 430 by 493, we get 0 and a remainder of 430.
The next digit of our result is 0. 
Result so far: 176855.0649
Subtract 0 from 430 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 14:
4300 divided by 493 is 8 with a remainder of 356.
Put 8 as the next digit of the answer. 
Result so far: 176855.064908
Subtracting 3944 from 4300 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

On to step 15:
If we divide 3560 by 493, we get 7 and a remainder of 109.
Put 7 as the next digit of the answer. 
Result so far: 176855.0649087
If we subtract 3451 from 3560, we get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Going ahead to step 16:
The number 493 fits into 1090 2 times, leaving a remainder of 104.
The number 2 becomes the next digit in our result. 
Result so far: 176855.06490872
Subtracting 986 from 1090 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The final result is 176855.06490872 with a remainder of 1.04e-07.
