We divide 511559 by 81
Our goal is to divide 511559 by 81.

Let's proceed to step 1:
81 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 81

Moving on to step 2:
If we divide 51 by 81, we get 0 and a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Include the next digit (1) from the dividend after 51, then repeat: 511 / 81

Going ahead to step 3:
The number 81 fits into 511 6 times, leaving a remainder of 25.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 486 from 511 leaves us with 25.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 81

Going ahead to step 4:
The number 81 fits into 255 3 times, leaving a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
The remainder is 12 after subtracting 243 from 255.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 81

Moving on to step 5:
If we divide 125 by 81, we get 1 and a remainder of 44.
Write down 1 as next digit of the result. 
Result so far: 631.0
Subtract 81 from 125 to get 44.
Bring next digit (9) of the dividend behind the 44 and repeat the process: 449 / 81

On to step 6:
449 divided by 81 is 5 with a remainder of 44.
The next digit of our result is 5. 
Result so far: 6315.0
The remainder is 44 after subtracting 405 from 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 7:
81 can be fit into 440 5 times, resulting in a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 6315.5
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.

Moving on to step 8:
When dividing 350 by 81, we get 4 with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 6315.54
Subtract 324 from 350 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
81 can be fit into 260 3 times, resulting in a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 6315.543
If we take 243 away from 260, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 10:
81 goes into 170 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 6315.5432
Subtracting 162 from 170 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
The number 81 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 6315.5432
Deduct 0 from 80 and we're left 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.

Advancing to step 12:
If we divide 800 by 81, we get 9 and a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 6315.543209
The remainder is 71 after subtracting 729 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 13:
If we divide 710 by 81, we get 8 and a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 6315.5432098
If we take 648 away from 710, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 14:
81 can be fit into 620 7 times, resulting in a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 6315.54320987
If we take 567 away from 620, we end up 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.

In conclusion, the division gives 6315.54320987 with a balance of 5.3e-08.
