Going ahead to step 4:
7807 divided by 863 is 9 with a remainder of 40.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 40 after subtracting 7767 from 7807.
Take the next digit (7) from the dividend and append it to 40, then repeat: 407 / 863

On to step 5:
If we divide 407 by 863, we get 0 and a remainder of 407.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
The remainder is 407 after subtracting 0 from 407.
Append the next digit (8) from the dividend to 407 and continue with: 4078 / 863

Step 6:
863 goes into 4078 4 times with a remainder of 626.
Use 4 as the next digit of our solution. 
Result so far: 904.0
Subtract 3452 from 4078 to get 626.
Append the next digit (1) from the dividend to 626 and continue with: 6261 / 863

Let's proceed to step 7:
6261 divided by 863 is 7 with a remainder of 220.
The number 7 becomes the next digit in our result. 
Result so far: 9047.0
Subtracting 6041 from 6261 leaves us with 220.
Take the next digit (8) from the dividend and append it to 220, then repeat: 2208 / 863

Going ahead to step 8:
If we divide 2208 by 863, we get 2 and a remainder of 482.
The next digit of our result is 2. 
Result so far: 90472.0
Subtract 1726 from 2208 to get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Advancing to step 9:
When dividing 4820 by 863, we get 5 with a remainder of 505.
Write down 5 as next digit of the result. 
Result so far: 90472.5
Deduct 4315 from 4820 and we're left with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Step 10:
5050 divided by 863 is 5 with a remainder of 735.
Use 5 as the next digit of our solution. 
Result so far: 90472.55
Subtracting 4315 from 5050 leaves us with 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

The quotient of the division is 90472.55, and the remainder is 0.735.
