Write down 7 as next digit of the result. 
Result so far: 4537.7
Deduct 6027 from 6810 and we're left with 783.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7830, and continue the process.

Let's proceed to step 9:
861 goes into 7830 9 times with a remainder of 81.
The number 9 becomes the next digit in our result. 
Result so far: 4537.79
Subtracting 7749 from 7830 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 10:
If we divide 810 by 861, we get 0 and a remainder of 810.
Write down 0 as next digit of the result. 
Result so far: 4537.79
Subtracting 0 from 810 leaves us with 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Step 11:
861 can be fit into 8100 9 times, resulting in a remainder of 351.
Write down 9 as next digit of the result. 
Result so far: 4537.7909
Subtract 7749 from 8100 to get 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Moving on to step 12:
3510 divided by 861 is 4 with a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 4537.79094
Subtracting 3444 from 3510 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 13:
If we divide 660 by 861, we get 0 and a remainder of 660.
Write down 0 as next digit of the result. 
Result so far: 4537.79094
Subtract 0 from 660 to get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 14:
When dividing 6600 by 861, we get 7 with a remainder of 573.
Put 7 as the next digit of the answer. 
Result so far: 4537.7909407
The remainder is 573 after subtracting 6027 from 6600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Step 15:
When dividing 5730 by 861, we get 6 with a remainder of 564.
Put 6 as the next digit of the answer. 
Result so far: 4537.79094076
If we subtract 5166 from 5730, we get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

The quotient of the division is 4537.79094076, and the remainder is 5.64e-07.
