487643 divided by 81 
Let's see how many times 81 fits into 487643.

Advancing to step 1:
4 divided by 81 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 81

Let's proceed to step 2:
81 goes into 48 0 times with a remainder of 48.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Append the next digit (7) from the dividend to 48 and continue with: 487 / 81

Let's proceed to step 3:
81 can be fit into 487 6 times, resulting in a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 1 after subtracting 486 from 487.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 81

On to step 4:
If we divide 16 by 81, we get 0 and a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 60.0
The remainder is 16 after subtracting 0 from 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 81

Going ahead to step 5:
When dividing 164 by 81, we get 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 602.0
Deduct 162 from 164 and we're left with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 81

On to step 6:
If we divide 23 by 81, we get 0 and a remainder of 23.
The next digit of our result is 0. 
Result so far: 6020.0
The remainder is 23 after subtracting 0 from 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
81 goes into 230 2 times with a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 6020.2
If we subtract 162 from 230, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 8:
680 divided by 81 is 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 6020.28
Subtracting 648 from 680 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
When dividing 320 by 81, we get 3 with a remainder of 77.
The number 3 becomes the next digit in our result. 
Result so far: 6020.283
The remainder is 77 after subtracting 243 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 10:
81 goes into 770 9 times with a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 6020.2839
If we subtract 729 from 770, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 11:
81 can be fit into 410 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 6020.28395
Subtracting 405 from 410 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 12:
The number 81 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 6020.28395
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
81 goes into 500 6 times with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 6020.2839506
The remainder is 14 after subtracting 486 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 14:
81 goes into 140 1 times with a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 6020.28395061
If we subtract 81 from 140, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

In conclusion, the division gives 6020.28395061 with a balance of 5.9e-08.
