516961 divided by 81 
We want to divide 516961 by 81.

On to step 1:
When dividing 5 by 81, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 81

Advancing to step 2:
If we divide 51 by 81, we get 0 and a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Append the next digit (6) from the dividend to 51 and continue with: 516 / 81

Step 3:
81 can be fit into 516 6 times, resulting in a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 486 from 516 leaves us with 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 81

Moving on to step 4:
If we divide 309 by 81, we get 3 and a remainder of 66.
The next digit of our result is 3. 
Result so far: 63.0
If we take 243 away from 309, we end up with 66.
Bring next digit (6) of the dividend behind the 66 and repeat the process: 666 / 81

On to step 5:
81 goes into 666 8 times with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 638.0
Deduct 648 from 666 and we're left with 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 81

Moving on to step 6:
If we divide 181 by 81, we get 2 and a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 6382.0
If we subtract 162 from 181, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
81 can be fit into 190 2 times, resulting in a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 6382.2
Subtract 162 from 190 to 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.

Going ahead to step 8:
280 divided by 81 is 3 with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 6382.23
Subtract 243 from 280 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 9:
When dividing 370 by 81, we get 4 with a remainder of 46.
The next digit of our result is 4. 
Result so far: 6382.234
If we subtract 324 from 370, we get 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 10:
460 divided by 81 is 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 6382.2345
Subtract 405 from 460 to 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 11:
If we divide 550 by 81, we get 6 and a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 6382.23456
Subtracting 486 from 550 leaves us 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.

Step 12:
81 goes into 640 7 times with a remainder of 73.
The next digit of our result is 7. 
Result so far: 6382.234567
The remainder is 73 after subtracting 567 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 13:
730 divided by 81 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 6382.2345679
Deduct 729 from 730 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 14:
If we divide 10 by 81, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 6382.2345679
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 6382.2345679, with a leftover of 1e-08.
