85781624 divided by 863 
We want to divide 85781624 by 863.

Moving on to step 1:
8 divided by 863 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 863

Step 2:
When dividing 85 by 863, we get 0 with a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Include the next digit (7) from the dividend after 85, then repeat: 857 / 863

Advancing to step 3:
863 goes into 857 0 times with a remainder of 857.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 857, we get 857.
Take the next digit (8) from the dividend and append it to 857, then repeat: 8578 / 863

Step 4:
8578 divided by 863 is 9 with a remainder of 811.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 7767 from 8578 to get 811.
Include the next digit (1) from the dividend after 811, then repeat: 8111 / 863

Advancing to step 5:
863 goes into 8111 9 times with a remainder of 344.
The next digit of our result is 9. 
Result so far: 99.0
The remainder is 344 after subtracting 7767 from 8111.
Fetch the next digit (6) from the dividend, attach it to 344 and continue: 3446 / 863

Going ahead to step 6:
863 goes into 3446 3 times with a remainder of 857.
Put 3 as the next digit of the answer. 
Result so far: 993.0
If we take 2589 away from 3446, we end up with 857.
Include the next digit (2) from the dividend after 857, then repeat: 8572 / 863

Let's proceed to step 7:
863 goes into 8572 9 times with a remainder of 805.
The next digit of our result is 9. 
Result so far: 9939.0
Subtracting 7767 from 8572 leaves us with 805.
Append the next digit (4) from the dividend to 805 and continue with: 8054 / 863

Moving on to step 8:
863 goes into 8054 9 times with a remainder of 287.
The number 9 becomes the next digit in our result. 
Result so far: 99399.0
Subtracting 7767 from 8054 leaves us with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Let's proceed to step 9:
The number 863 fits into 2870 3 times, leaving a remainder of 281.
Write down 3 as next digit of the result. 
Result so far: 99399.3
The remainder is 281 after subtracting 2589 from 2870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Going ahead to step 10:
If we divide 2810 by 863, we get 3 and a remainder of 221.
Record the quotient 3 as the next digit in the result. 
Result so far: 99399.33
Subtract 2589 from 2810 to get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

The quotient of the division is 99399.33, and the remainder is 0.221.
