531332 divided by 81 
We want to figure out the number of times 531332 can be divided by 81.

On 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
Subtract 0 from 5 to get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 81

Going ahead to step 2:
When dividing 53 by 81, we get 0 with a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Append the next digit (1) from the dividend to 53 and continue with: 531 / 81

Step 3:
The number 81 fits into 531 6 times, leaving a remainder of 45.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 486 from 531 leaves us with 45.
Append the next digit (3) from the dividend to 45 and continue with: 453 / 81

Let's proceed to step 4:
81 can be fit into 453 5 times, resulting in a remainder of 48.
Write down 5 as next digit of the result. 
Result so far: 65.0
Deduct 405 from 453 and we're left with 48.
Bring next digit (3) of the dividend behind the 48 and repeat the process: 483 / 81

Step 5:
81 goes into 483 5 times with a remainder of 78.
The number 5 becomes the next digit in our result. 
Result so far: 655.0
Subtract 405 from 483 to get 78.
Append the next digit (2) from the dividend to 78 and continue with: 782 / 81

Let's proceed to step 6:
If we divide 782 by 81, we get 9 and a remainder of 53.
Use 9 as the next digit of our solution. 
Result so far: 6559.0
The remainder is 53 after subtracting 729 from 782.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 7:
The number 81 fits into 530 6 times, leaving a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 6559.6
If we take 486 away from 530, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 8:
If we divide 440 by 81, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 6559.65
The remainder is 35 after subtracting 405 from 440.
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 9:
350 divided by 81 is 4 with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 6559.654
If we take 324 away from 350, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
260 divided by 81 is 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 6559.6543
Subtracting 243 from 260 leaves us 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.

Step 11:
If we divide 170 by 81, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 6559.65432
The remainder is 8 after subtracting 162 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
81 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 6559.65432
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.

Going ahead to step 13:
81 can be fit into 800 9 times, resulting in a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 6559.6543209
Deduct 729 from 800 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 14:
When dividing 710 by 81, we get 8 with a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 6559.65432098
Subtract 648 from 710 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Our division results in 6559.65432098 with a remaining 6.2e-08.
