We look at the division of 657963 by 81 
Let's see how many times 81 fits into 657963.

Step 1:
The number 81 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 81

Moving on to step 2:
When dividing 65 by 81, we get 0 with a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Grab the next digit (7) from the dividend, add it to 65, then carry on: 657 / 81

Going ahead to step 3:
81 goes into 657 8 times with a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 648 away from 657, we end up with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 81

Going ahead to step 4:
99 divided by 81 is 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
If we subtract 81 from 99, we get 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 81

Step 5:
81 goes into 186 2 times with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 812.0
The remainder is 24 after subtracting 162 from 186.
Append the next digit (3) from the dividend to 24 and continue with: 243 / 81

Moving on to step 6:
If we divide 243 by 81, we get 3 and a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 8123.0
Subtracting 243 from 243 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
The number 81 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8123.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
If we divide 0 by 81, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 8123.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 8123.0 with a remainder of 0.0.
