Let's divide 509047 by 81
We want to figure out the number of times 509047 can be divided by 81.

On to step 1:
The number 81 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 81

On to step 2:
81 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Take the next digit (9) from the dividend and append it to 50, then repeat: 509 / 81

Moving on to step 3:
The number 81 fits into 509 6 times, leaving a remainder of 23.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 486 from 509, we get 23.
Take the next digit (0) from the dividend and append it to 23, then repeat: 230 / 81

Step 4:
81 can be fit into 230 2 times, resulting in a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 62.0
The remainder is 68 after subtracting 162 from 230.
Append the next digit (4) from the dividend to 68 and continue with: 684 / 81

Step 5:
If we divide 684 by 81, we get 8 and a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 628.0
Subtracting 648 from 684 leaves us with 36.
Bring next digit (7) of the dividend behind the 36 and repeat the process: 367 / 81

Going ahead to step 6:
When dividing 367 by 81, we get 4 with a remainder of 43.
Write down 4 as next digit of the result. 
Result so far: 6284.0
If we take 324 away from 367, we end up 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.

Going ahead to step 7:
When dividing 430 by 81, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 6284.5
If we subtract 405 from 430, we get 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 8:
250 divided by 81 is 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 6284.53
Deduct 243 from 250 and we're left with 7.
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 9:
70 divided by 81 is 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 6284.53
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
81 goes into 700 8 times with a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 6284.5308
The remainder is 52 after subtracting 648 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 11:
The number 81 fits into 520 6 times, leaving a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 6284.53086
The remainder is 34 after subtracting 486 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 12:
81 goes into 340 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 6284.530864
If we subtract 324 from 340, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
81 can be fit into 160 1 times, resulting in a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 6284.5308641
Deduct 81 from 160 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 14:
When dividing 790 by 81, we get 9 with a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 6284.53086419
The remainder is 61 after subtracting 729 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

The final result is 6284.53086419 with a remainder of 6.1e-08.
