Put 8 as the next digit of the answer. 
Result so far: 2168.0
The remainder is 467 after subtracting 6456 from 6923.
Include the next digit (0) from the dividend after 467, then repeat: 4670 / 807

Let's proceed to step 8:
When dividing 4670 by 807, we get 5 with a remainder of 635.
Use 5 as the next digit of our solution. 
Result so far: 21685.0
If we subtract 4035 from 4670, we get 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Moving on to step 9:
807 goes into 6350 7 times with a remainder of 701.
The number 7 becomes the next digit in our result. 
Result so far: 21685.7
Subtracting 5649 from 6350 leaves us with 701.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7010, and continue the process.

On to step 10:
7010 divided by 807 is 8 with a remainder of 554.
Put 8 as the next digit of the answer. 
Result so far: 21685.78
Subtracting 6456 from 7010 leaves us with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Step 11:
5540 divided by 807 is 6 with a remainder of 698.
Use 6 as the next digit of our solution. 
Result so far: 21685.786
Subtracting 4842 from 5540 leaves us with 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

On to step 12:
807 goes into 6980 8 times with a remainder of 524.
The next digit of our result is 8. 
Result so far: 21685.7868
Deduct 6456 from 6980 and we're left with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Let's proceed to step 13:
5240 divided by 807 is 6 with a remainder of 398.
Record the quotient 6 as the next digit in the result. 
Result so far: 21685.78686
Subtract 4842 from 5240 to get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Let's proceed to step 14:
807 can be fit into 3980 4 times, resulting in a remainder of 752.
The number 4 becomes the next digit in our result. 
Result so far: 21685.786864
If we subtract 3228 from 3980, we get 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Advancing to step 15:
807 goes into 7520 9 times with a remainder of 257.
Put 9 as the next digit of the answer. 
Result so far: 21685.7868649
If we subtract 7263 from 7520, we get 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Step 16:
2570 divided by 807 is 3 with a remainder of 149.
The number 3 becomes the next digit in our result. 
Result so far: 21685.78686493
If we take 2421 away from 2570, we end up with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

In conclusion, the division gives 21685.78686493 with a balance of 1.49e-07.
