We're dividing 500309 by 81 
We want to figure out the number of times 500309 can be divided by 81.

Step 1:
81 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 81

Going ahead to step 2:
81 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Bring next digit (0) of the dividend behind the 50 and repeat the process: 500 / 81

Going ahead to step 3:
When dividing 500 by 81, we get 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 486 from 500 and we're left with 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 81

Let's proceed to step 4:
81 goes into 143 1 times with a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 61.0
The remainder is 62 after subtracting 81 from 143.
Grab the next digit (0) from the dividend, add it to 62, then carry on: 620 / 81

Moving on to step 5:
If we divide 620 by 81, we get 7 and a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 617.0
The remainder is 53 after subtracting 567 from 620.
Include the next digit (9) from the dividend after 53, then repeat: 539 / 81

Advancing to step 6:
If we divide 539 by 81, we get 6 and a remainder of 53.
Write down 6 as next digit of the result. 
Result so far: 6176.0
Deduct 486 from 539 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 7:
530 divided by 81 is 6 with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 6176.6
Subtract 486 from 530 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 8:
The number 81 fits into 440 5 times, leaving a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 6176.65
Deduct 405 from 440 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
When dividing 350 by 81, we get 4 with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 6176.654
If we subtract 324 from 350, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 10:
81 can be fit into 260 3 times, resulting in a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 6176.6543
If we subtract 243 from 260, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 11:
81 can be fit into 170 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 6176.65432
If we subtract 162 from 170, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
81 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 6176.65432
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 13:
81 goes into 800 9 times with a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 6176.6543209
The remainder is 71 after subtracting 729 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 14:
81 can be fit into 710 8 times, resulting in a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 6176.65432098
If we subtract 648 from 710, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

After the division, we end up with 6176.65432098 and a remainder of 6.2e-08.
