We divide 963855 by 81
We want to divide 963855 by 81.

Advancing to step 1:
If we divide 9 by 81, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 81

Going ahead to step 2:
The number 81 fits into 96 1 times, leaving a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 81 from 96 to get 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 81

Step 3:
153 divided by 81 is 1 with a remainder of 72.
The next digit of our result is 1. 
Result so far: 11.0
If we take 81 away from 153, we end up with 72.
Take the next digit (8) from the dividend and append it to 72, then repeat: 728 / 81

Let's proceed to step 4:
81 goes into 728 8 times with a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 118.0
The remainder is 80 after subtracting 648 from 728.
Take the next digit (5) from the dividend and append it to 80, then repeat: 805 / 81

Moving on to step 5:
81 goes into 805 9 times with a remainder of 76.
Record the quotient 9 as the next digit in the result. 
Result so far: 1189.0
The remainder is 76 after subtracting 729 from 805.
Bring next digit (5) of the dividend behind the 76 and repeat the process: 765 / 81

Step 6:
When dividing 765 by 81, we get 9 with a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 11899.0
Deduct 729 from 765 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 7:
When dividing 360 by 81, we get 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 11899.4
If we subtract 324 from 360, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
If we divide 360 by 81, we get 4 and a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 11899.44
If we subtract 324 from 360, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 11899.44 and a remainder of 0.036.
