Let's divide 515552 by 81
We're looking to find how many times 81 goes into 515552.

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
Subtracting 0 from 5 leaves us with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 81

Step 2:
51 divided by 81 is 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Append the next digit (5) from the dividend to 51 and continue with: 515 / 81

Going ahead to step 3:
When dividing 515 by 81, we get 6 with a remainder of 29.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 29 after subtracting 486 from 515.
Take the next digit (5) from the dividend and append it to 29, then repeat: 295 / 81

Going ahead to step 4:
81 goes into 295 3 times with a remainder of 52.
Put 3 as the next digit of the answer. 
Result so far: 63.0
If we take 243 away from 295, we end up with 52.
Append the next digit (5) from the dividend to 52 and continue with: 525 / 81

On to step 5:
The number 81 fits into 525 6 times, leaving a remainder of 39.
Write down 6 as next digit of the result. 
Result so far: 636.0
Deduct 486 from 525 and we're left with 39.
Fetch the next digit (2) from the dividend, attach it to 39 and continue: 392 / 81

Step 6:
81 can be fit into 392 4 times, resulting in a remainder of 68.
The next digit of our result is 4. 
Result so far: 6364.0
If we subtract 324 from 392, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 7:
680 divided by 81 is 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 6364.8
If we take 648 away from 680, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 8:
If we divide 320 by 81, we get 3 and a remainder of 77.
The next digit of our result is 3. 
Result so far: 6364.83
The remainder is 77 after subtracting 243 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 9:
If we divide 770 by 81, we get 9 and a remainder of 41.
The next digit of our result is 9. 
Result so far: 6364.839
Subtract 729 from 770 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 10:
81 goes into 410 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 6364.8395
The remainder is 5 after subtracting 405 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 11:
81 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 6364.8395
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 12:
The number 81 fits into 500 6 times, leaving a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 6364.839506
If we take 486 away from 500, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 13:
The number 81 fits into 140 1 times, leaving a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 6364.8395061
The remainder is 59 after subtracting 81 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 14:
590 divided by 81 is 7 with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 6364.83950617
If we subtract 567 from 590, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 6364.83950617, with a leftover of 2.3e-08.
