We're dividing 543871 by 81 
Let's see how many times 81 fits into 543871.

Let's proceed to step 1:
The number 81 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 81

Let's proceed to step 2:
The number 81 fits into 54 0 times, leaving a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Include the next digit (3) from the dividend after 54, then repeat: 543 / 81

Advancing to step 3:
The number 81 fits into 543 6 times, leaving a remainder of 57.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 57 after subtracting 486 from 543.
Append the next digit (8) from the dividend to 57 and continue with: 578 / 81

Step 4:
81 can be fit into 578 7 times, resulting in a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 67.0
If we take 567 away from 578, we end up with 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 81

Let's proceed to step 5:
When dividing 117 by 81, we get 1 with a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 671.0
The remainder is 36 after subtracting 81 from 117.
Grab the next digit (1) from the dividend, add it to 36, then carry on: 361 / 81

Moving on to step 6:
The number 81 fits into 361 4 times, leaving a remainder of 37.
The number 4 becomes the next digit in our result. 
Result so far: 6714.0
Subtract 324 from 361 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 7:
81 can be fit into 370 4 times, resulting in a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 6714.4
The remainder is 46 after subtracting 324 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 8:
81 goes into 460 5 times with a remainder of 55.
The next digit of our result is 5. 
Result so far: 6714.45
Subtract 405 from 460 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 9:
The number 81 fits into 550 6 times, leaving a remainder of 64.
The next digit of our result is 6. 
Result so far: 6714.456
If we take 486 away from 550, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 10:
81 goes into 640 7 times with a remainder of 73.
Use 7 as the next digit of our solution. 
Result so far: 6714.4567
Subtracting 567 from 640 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 11:
If we divide 730 by 81, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 6714.45679
Deduct 729 from 730 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 12:
81 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 6714.45679
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
When dividing 100 by 81, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 6714.4567901
The remainder is 19 after subtracting 81 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 14:
The number 81 fits into 190 2 times, leaving a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 6714.45679012
Deduct 162 from 190 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 6714.45679012 with a remaining 2.8e-08.
