Bring next digit (4) of the dividend behind the 671 and repeat the process: 6714 / 864

Moving on to step 4:
The number 864 fits into 6714 7 times, leaving a remainder of 666.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 6048 from 6714 leaves us with 666.
Append the next digit (3) from the dividend to 666 and continue with: 6663 / 864

Let's proceed to step 5:
If we divide 6663 by 864, we get 7 and a remainder of 615.
The next digit of our result is 7. 
Result so far: 77.0
Deduct 6048 from 6663 and we're left with 615.
Grab the next digit (4) from the dividend, add it to 615, then carry on: 6154 / 864

Moving on to step 6:
When dividing 6154 by 864, we get 7 with a remainder of 106.
Use 7 as the next digit of our solution. 
Result so far: 777.0
Deduct 6048 from 6154 and we're left with 106.
Append the next digit (1) from the dividend to 106 and continue with: 1061 / 864

On to step 7:
864 goes into 1061 1 times with a remainder of 197.
Use 1 as the next digit of our solution. 
Result so far: 7771.0
Deduct 864 from 1061 and we're left with 197.
Append the next digit (9) from the dividend to 197 and continue with: 1979 / 864

Step 8:
864 goes into 1979 2 times with a remainder of 251.
Record the quotient 2 as the next digit in the result. 
Result so far: 77712.0
Deduct 1728 from 1979 and we're left with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Step 9:
The number 864 fits into 2510 2 times, leaving a remainder of 782.
Put 2 as the next digit of the answer. 
Result so far: 77712.2
Deduct 1728 from 2510 and we're left with 782.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7820, and continue the process.

Going ahead to step 10:
If we divide 7820 by 864, we get 9 and a remainder of 44.
The next digit of our result is 9. 
Result so far: 77712.29
Subtracting 7776 from 7820 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 11:
440 divided by 864 is 0 with a remainder of 440.
The next digit of our result is 0. 
Result so far: 77712.29
If we take 0 away from 440, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Let's proceed to step 12:
The number 864 fits into 4400 5 times, leaving a remainder of 80.
Write down 5 as next digit of the result. 
Result so far: 77712.2905
Subtract 4320 from 4400 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
800 divided by 864 is 0 with a remainder of 800.
The next digit of our result is 0. 
Result so far: 77712.2905
The remainder is 800 after subtracting 0 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Going ahead to step 14:
864 can be fit into 8000 9 times, resulting in a remainder of 224.
The next digit of our result is 9. 
Result so far: 77712.290509
The remainder is 224 after subtracting 7776 from 8000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 15:
If we divide 2240 by 864, we get 2 and a remainder of 512.
The next digit of our result is 2. 
Result so far: 77712.2905092
Subtracting 1728 from 2240 leaves us with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Step 16:
864 can be fit into 5120 5 times, resulting in a remainder of 800.
Use 5 as the next digit of our solution. 
Result so far: 77712.29050925
If we subtract 4320 from 5120, we get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

After the division, we end up with 77712.29050925 and a remainder of 8e-07.
