We look at the division of 80843860 by 509 
Let's see how many times 509 fits into 80843860.

Let's proceed to step 1:
If we divide 8 by 509, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 509

Advancing to step 2:
509 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Append the next digit (8) from the dividend to 80 and continue with: 808 / 509

Moving on to step 3:
808 divided by 509 is 1 with a remainder of 299.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 509 from 808 leaves us with 299.
Include the next digit (4) from the dividend after 299, then repeat: 2994 / 509

Moving on to step 4:
If we divide 2994 by 509, we get 5 and a remainder of 449.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 2545 away from 2994, we end up with 449.
Grab the next digit (3) from the dividend, add it to 449, then carry on: 4493 / 509

Moving on to step 5:
4493 divided by 509 is 8 with a remainder of 421.
Record the quotient 8 as the next digit in the result. 
Result so far: 158.0
If we take 4072 away from 4493, we end up with 421.
Grab the next digit (8) from the dividend, add it to 421, then carry on: 4218 / 509

Advancing to step 6:
4218 divided by 509 is 8 with a remainder of 146.
Record the quotient 8 as the next digit in the result. 
Result so far: 1588.0
The remainder is 146 after subtracting 4072 from 4218.
Take the next digit (6) from the dividend and append it to 146, then repeat: 1466 / 509

Moving on to step 7:
If we divide 1466 by 509, we get 2 and a remainder of 448.
Use 2 as the next digit of our solution. 
Result so far: 15882.0
Subtracting 1018 from 1466 leaves us with 448.
Fetch the next digit (0) from the dividend, attach it to 448 and continue: 4480 / 509

On to step 8:
The number 509 fits into 4480 8 times, leaving a remainder of 408.
The next digit of our result is 8. 
Result so far: 158828.0
The remainder is 408 after subtracting 4072 from 4480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

On to step 9:
The number 509 fits into 4080 8 times, leaving a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 158828.8
Subtract 4072 from 4080 to get 8.
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 10:
509 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 158828.8
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.

Step 11:
If we divide 800 by 509, we get 1 and a remainder of 291.
The number 1 becomes the next digit in our result. 
Result so far: 158828.801
Subtract 509 from 800 to get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

On to step 12:
The number 509 fits into 2910 5 times, leaving a remainder of 365.
Record the quotient 5 as the next digit in the result. 
Result so far: 158828.8015
If we take 2545 away from 2910, we end up with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Step 13:
If we divide 3650 by 509, we get 7 and a remainder of 87.
Record the quotient 7 as the next digit in the result. 
Result so far: 158828.80157
Subtract 3563 from 3650 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 14:
509 goes into 870 1 times with a remainder of 361.
Use 1 as the next digit of our solution. 
Result so far: 158828.801571
Subtract 509 from 870 to get 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Step 15:
509 can be fit into 3610 7 times, resulting in a remainder of 47.
Put 7 as the next digit of the answer. 
Result so far: 158828.8015717
If we take 3563 away from 3610, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 16:
If we divide 470 by 509, we get 0 and a remainder of 470.
Write down 0 as next digit of the result. 
Result so far: 158828.8015717
Subtract 0 from 470 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

After the division, we end up with 158828.8015717 and a remainder of 4.7e-07.
