81314093 ÷ 531 
We want to figure out the number of times 81314093 can be divided by 531.

Let's proceed to step 1:
When dividing 8 by 531, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 531

Let's proceed to step 2:
If we divide 81 by 531, we get 0 and a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Append the next digit (3) from the dividend to 81 and continue with: 813 / 531

Moving on to step 3:
The number 531 fits into 813 1 times, leaving a remainder of 282.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 531 from 813 and we're left with 282.
Include the next digit (1) from the dividend after 282, then repeat: 2821 / 531

Moving on to step 4:
The number 531 fits into 2821 5 times, leaving a remainder of 166.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 166 after subtracting 2655 from 2821.
Include the next digit (4) from the dividend after 166, then repeat: 1664 / 531

Moving on to step 5:
531 can be fit into 1664 3 times, resulting in a remainder of 71.
The number 3 becomes the next digit in our result. 
Result so far: 153.0
If we take 1593 away from 1664, we end up with 71.
Fetch the next digit (0) from the dividend, attach it to 71 and continue: 710 / 531

Let's proceed to step 6:
531 goes into 710 1 times with a remainder of 179.
The number 1 becomes the next digit in our result. 
Result so far: 1531.0
The remainder is 179 after subtracting 531 from 710.
Take the next digit (9) from the dividend and append it to 179, then repeat: 1799 / 531

Going ahead to step 7:
531 can be fit into 1799 3 times, resulting in a remainder of 206.
The number 3 becomes the next digit in our result. 
Result so far: 15313.0
If we subtract 1593 from 1799, we get 206.
Fetch the next digit (3) from the dividend, attach it to 206 and continue: 2063 / 531

Step 8:
531 can be fit into 2063 3 times, resulting in a remainder of 470.
Write down 3 as next digit of the result. 
Result so far: 153133.0
The remainder is 470 after subtracting 1593 from 2063.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Going ahead to step 9:
If we divide 4700 by 531, we get 8 and a remainder of 452.
Use 8 as the next digit of our solution. 
Result so far: 153133.8
If we take 4248 away from 4700, we end up with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Moving on to step 10:
4520 divided by 531 is 8 with a remainder of 272.
The next digit of our result is 8. 
Result so far: 153133.88
If we take 4248 away from 4520, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

The final result is 153133.88 with a remainder of 0.272.
