We're dividing 8241575 by 509 
Our goal is to divide 8241575 by 509.

Going ahead to step 1:
When dividing 8 by 509, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 509

Step 2:
82 divided by 509 is 0 with a remainder of 82.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 82 leaves us with 82.
Append the next digit (4) from the dividend to 82 and continue with: 824 / 509

Moving on to step 3:
If we divide 824 by 509, we get 1 and a remainder of 315.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 509 from 824 and we're left with 315.
Fetch the next digit (1) from the dividend, attach it to 315 and continue: 3151 / 509

Step 4:
509 goes into 3151 6 times with a remainder of 97.
The next digit of our result is 6. 
Result so far: 16.0
If we take 3054 away from 3151, we end up with 97.
Append the next digit (5) from the dividend to 97 and continue with: 975 / 509

Let's proceed to step 5:
509 goes into 975 1 times with a remainder of 466.
The next digit of our result is 1. 
Result so far: 161.0
Subtracting 509 from 975 leaves us with 466.
Take the next digit (7) from the dividend and append it to 466, then repeat: 4667 / 509

Moving on to step 6:
4667 divided by 509 is 9 with a remainder of 86.
Put 9 as the next digit of the answer. 
Result so far: 1619.0
If we subtract 4581 from 4667, we get 86.
Include the next digit (5) from the dividend after 86, then repeat: 865 / 509

Advancing to step 7:
The number 509 fits into 865 1 times, leaving a remainder of 356.
Use 1 as the next digit of our solution. 
Result so far: 16191.0
The remainder is 356 after subtracting 509 from 865.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Moving on to step 8:
509 goes into 3560 6 times with a remainder of 506.
Write down 6 as next digit of the result. 
Result so far: 16191.6
If we take 3054 away from 3560, we end up with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Moving on to step 9:
The number 509 fits into 5060 9 times, leaving a remainder of 479.
The number 9 becomes the next digit in our result. 
Result so far: 16191.69
If we take 4581 away from 5060, we end up with 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Step 10:
The number 509 fits into 4790 9 times, leaving a remainder of 209.
Put 9 as the next digit of the answer. 
Result so far: 16191.699
If we subtract 4581 from 4790, we get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

The final outcome is 16191.699, with a leftover of 0.0209.
