235602 divided by 81 
Let's see how many times 81 fits into 235602.

Step 1:
The number 81 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 81

Advancing to step 2:
23 divided by 81 is 0 with a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 81

On to step 3:
235 divided by 81 is 2 with a remainder of 73.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 162 from 235, we get 73.
Include the next digit (6) from the dividend after 73, then repeat: 736 / 81

Step 4:
The number 81 fits into 736 9 times, leaving a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Subtract 729 from 736 to get 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 81

Going ahead to step 5:
81 can be fit into 70 0 times, resulting in a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 290.0
Subtract 0 from 70 to get 70.
Include the next digit (2) from the dividend after 70, then repeat: 702 / 81

Moving on to step 6:
81 goes into 702 8 times with a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 2908.0
Subtract 648 from 702 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 7:
If we divide 540 by 81, we get 6 and a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 2908.6
If we subtract 486 from 540, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 8:
The number 81 fits into 540 6 times, leaving a remainder of 54.
Write down 6 as next digit of the result. 
Result so far: 2908.66
If we take 486 away from 540, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 2908.66 with a remainder of 0.054.
