Let's divide 509489 by 81
We want to divide 509489 by 81.

Moving on 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
Deduct 0 from 5 and we're left with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 81

Moving on to step 2:
The number 81 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Bring next digit (9) of the dividend behind the 50 and repeat the process: 509 / 81

Moving on to step 3:
The number 81 fits into 509 6 times, leaving a remainder of 23.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 23 after subtracting 486 from 509.
Fetch the next digit (4) from the dividend, attach it to 23 and continue: 234 / 81

Advancing to step 4:
When dividing 234 by 81, we get 2 with a remainder of 72.
The next digit of our result is 2. 
Result so far: 62.0
Subtract 162 from 234 to get 72.
Append the next digit (8) from the dividend to 72 and continue with: 728 / 81

Going ahead to step 5:
The number 81 fits into 728 8 times, leaving a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 628.0
Subtract 648 from 728 to get 80.
Bring next digit (9) of the dividend behind the 80 and repeat the process: 809 / 81

On to step 6:
The number 81 fits into 809 9 times, leaving a remainder of 80.
Put 9 as the next digit of the answer. 
Result so far: 6289.0
Subtracting 729 from 809 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 7:
81 goes into 800 9 times with a remainder of 71.
The next digit of our result is 9. 
Result so far: 6289.9
Subtract 729 from 800 to get 71.
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 8:
710 divided by 81 is 8 with a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 6289.98
The remainder is 62 after subtracting 648 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 9:
81 can be fit into 620 7 times, resulting in a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 6289.987
Deduct 567 from 620 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.

Advancing to step 10:
530 divided by 81 is 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 6289.9876
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.

Moving on to step 11:
81 goes into 440 5 times with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 6289.98765
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.

Going ahead to step 12:
The number 81 fits into 350 4 times, leaving a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 6289.987654
Deduct 324 from 350 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 13:
When dividing 260 by 81, we get 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 6289.9876543
Subtract 243 from 260 to 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.

Going ahead to step 14:
When dividing 170 by 81, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 6289.98765432
The remainder is 8 after subtracting 162 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 6289.98765432 with a remainder of 8e-09.
