We divide 537871 by 81
We're looking to find how many times 81 goes into 537871.

Step 1:
The number 81 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 81

Advancing to step 2:
81 goes into 53 0 times with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Fetch the next digit (7) from the dividend, attach it to 53 and continue: 537 / 81

Step 3:
The number 81 fits into 537 6 times, leaving a remainder of 51.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 486 from 537 to get 51.
Bring next digit (8) of the dividend behind the 51 and repeat the process: 518 / 81

Going ahead to step 4:
If we divide 518 by 81, we get 6 and a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 66.0
Subtracting 486 from 518 leaves us with 32.
Take the next digit (7) from the dividend and append it to 32, then repeat: 327 / 81

Let's proceed to step 5:
When dividing 327 by 81, we get 4 with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 664.0
The remainder is 3 after subtracting 324 from 327.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 81

On to step 6:
When dividing 31 by 81, we get 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 6640.0
Subtracting 0 from 31 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
310 divided by 81 is 3 with a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 6640.3
The remainder is 67 after subtracting 243 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 8:
81 can be fit into 670 8 times, resulting in a remainder of 22.
The next digit of our result is 8. 
Result so far: 6640.38
Subtracting 648 from 670 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 9:
81 goes into 220 2 times with a remainder of 58.
The next digit of our result is 2. 
Result so far: 6640.382
Subtract 162 from 220 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 10:
When dividing 580 by 81, we get 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 6640.3827
Deduct 567 from 580 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 11:
130 divided by 81 is 1 with a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 6640.38271
Subtracting 81 from 130 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 12:
81 can be fit into 490 6 times, resulting in a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 6640.382716
Subtract 486 from 490 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 13:
The number 81 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 6640.382716
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
If we divide 400 by 81, we get 4 and a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 6640.38271604
Deduct 324 from 400 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 6640.38271604, with a leftover of 7.6e-08.
