512728 divided by 81 
We want to divide 512728 by 81.

Moving on to step 1:
If we divide 5 by 81, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 81

Moving on to step 2:
81 can be fit into 51 0 times, resulting in a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Include the next digit (2) from the dividend after 51, then repeat: 512 / 81

On to step 3:
81 can be fit into 512 6 times, resulting in a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 26 after subtracting 486 from 512.
Fetch the next digit (7) from the dividend, attach it to 26 and continue: 267 / 81

Moving on to step 4:
The number 81 fits into 267 3 times, leaving a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 63.0
Subtract 243 from 267 to get 24.
Include the next digit (2) from the dividend after 24, then repeat: 242 / 81

Advancing to step 5:
The number 81 fits into 242 2 times, leaving a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 632.0
Subtracting 162 from 242 leaves us with 80.
Bring next digit (8) of the dividend behind the 80 and repeat the process: 808 / 81

Step 6:
81 can be fit into 808 9 times, resulting in a remainder of 79.
Write down 9 as next digit of the result. 
Result so far: 6329.0
If we subtract 729 from 808, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 7:
790 divided by 81 is 9 with a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 6329.9
Deduct 729 from 790 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 8:
The number 81 fits into 610 7 times, leaving a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 6329.97
Subtracting 567 from 610 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 9:
If we divide 430 by 81, we get 5 and a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 6329.975
If we take 405 away from 430, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 10:
81 can be fit into 250 3 times, resulting in a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 6329.9753
The remainder is 7 after subtracting 243 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 11:
When dividing 70 by 81, we get 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 6329.9753
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 12:
81 can be fit into 700 8 times, resulting in a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 6329.975308
If we subtract 648 from 700, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 13:
81 goes into 520 6 times with a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 6329.9753086
Subtract 486 from 520 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 14:
If we divide 340 by 81, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 6329.97530864
The remainder is 16 after subtracting 324 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 6329.97530864 with a remaining 1.6e-08.
