Let's divide 511552 by 81
We're looking to find how many times 81 goes into 511552.

Advancing to step 1:
When dividing 5 by 81, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 81

Advancing to step 2:
81 can be fit into 51 0 times, resulting in a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Include the next digit (1) from the dividend after 51, then repeat: 511 / 81

Step 3:
81 goes into 511 6 times with a remainder of 25.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 486 from 511 and we're left with 25.
Include the next digit (5) from the dividend after 25, then repeat: 255 / 81

On to step 4:
When dividing 255 by 81, we get 3 with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
Deduct 243 from 255 and we're left with 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 81

Going ahead to step 5:
The number 81 fits into 125 1 times, leaving a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 631.0
The remainder is 44 after subtracting 81 from 125.
Include the next digit (2) from the dividend after 44, then repeat: 442 / 81

On to step 6:
442 divided by 81 is 5 with a remainder of 37.
Record the quotient 5 as the next digit in the result. 
Result so far: 6315.0
The remainder is 37 after subtracting 405 from 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
The number 81 fits into 370 4 times, leaving a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 6315.4
The remainder is 46 after subtracting 324 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 8:
81 goes into 460 5 times with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 6315.45
Subtracting 405 from 460 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 9:
When dividing 550 by 81, we get 6 with a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 6315.456
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.

Going ahead to step 10:
640 divided by 81 is 7 with a remainder of 73.
Record the quotient 7 as the next digit in the result. 
Result so far: 6315.4567
If we take 567 away from 640, we end up 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.

Step 11:
730 divided by 81 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 6315.45679
Subtracting 729 from 730 leaves us 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.

On to step 12:
81 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 6315.45679
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
If we divide 100 by 81, we get 1 and a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 6315.4567901
Subtract 81 from 100 to 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.

Moving on to step 14:
The number 81 fits into 190 2 times, leaving a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 6315.45679012
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.

Our division results in 6315.45679012 with a remaining 2.8e-08.
