Let's divide 511840 by 81
We want to divide 511840 by 81.

Moving on to step 1:
81 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 81

Let's proceed to step 2:
81 can be fit into 51 0 times, resulting in a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Bring next digit (1) of the dividend behind the 51 and repeat the process: 511 / 81

Let's proceed to step 3:
511 divided by 81 is 6 with a remainder of 25.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 486 from 511 to get 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 81

Step 4:
258 divided by 81 is 3 with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 63.0
If we subtract 243 from 258, we get 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 81

Going ahead to step 5:
81 goes into 154 1 times with a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 631.0
Subtract 81 from 154 to get 73.
Fetch the next digit (0) from the dividend, attach it to 73 and continue: 730 / 81

Going ahead to step 6:
The number 81 fits into 730 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 6319.0
The remainder is 1 after subtracting 729 from 730.
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 7:
81 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 6319.0
If we subtract 0 from 10, we 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.

Advancing to step 8:
If we divide 100 by 81, we get 1 and a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 6319.01
If we take 81 away from 100, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 9:
If we divide 190 by 81, we get 2 and a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 6319.012
If we subtract 162 from 190, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
If we divide 280 by 81, we get 3 and a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 6319.0123
If we take 243 away from 280, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 11:
81 goes into 370 4 times with a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 6319.01234
Deduct 324 from 370 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 12:
81 can be fit into 460 5 times, resulting in a remainder of 55.
The next digit of our result is 5. 
Result so far: 6319.012345
If we subtract 405 from 460, we 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.

Moving on to step 13:
550 divided by 81 is 6 with a remainder of 64.
The next digit of our result is 6. 
Result so far: 6319.0123456
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.

On to step 14:
640 divided by 81 is 7 with a remainder of 73.
Write down 7 as next digit of the result. 
Result so far: 6319.01234567
Deduct 567 from 640 and we're left 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.

The final outcome is 6319.01234567, with a leftover of 7.3e-08.
