28343359 ÷ 509 
We want to divide 28343359 by 509.

On to step 1:
The number 509 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 509

Going ahead to step 2:
509 can be fit into 28 0 times, resulting in a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Take the next digit (3) from the dividend and append it to 28, then repeat: 283 / 509

Moving on to step 3:
When dividing 283 by 509, we get 0 with a remainder of 283.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 283 leaves us with 283.
Append the next digit (4) from the dividend to 283 and continue with: 2834 / 509

Advancing to step 4:
The number 509 fits into 2834 5 times, leaving a remainder of 289.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 2545 from 2834 and we're left with 289.
Grab the next digit (3) from the dividend, add it to 289, then carry on: 2893 / 509

Let's proceed to step 5:
If we divide 2893 by 509, we get 5 and a remainder of 348.
Use 5 as the next digit of our solution. 
Result so far: 55.0
If we subtract 2545 from 2893, we get 348.
Fetch the next digit (3) from the dividend, attach it to 348 and continue: 3483 / 509

Going ahead to step 6:
3483 divided by 509 is 6 with a remainder of 429.
Use 6 as the next digit of our solution. 
Result so far: 556.0
If we take 3054 away from 3483, we end up with 429.
Append the next digit (5) from the dividend to 429 and continue with: 4295 / 509

Moving on to step 7:
When dividing 4295 by 509, we get 8 with a remainder of 223.
Record the quotient 8 as the next digit in the result. 
Result so far: 5568.0
If we take 4072 away from 4295, we end up with 223.
Grab the next digit (9) from the dividend, add it to 223, then carry on: 2239 / 509

Advancing to step 8:
509 goes into 2239 4 times with a remainder of 203.
Record the quotient 4 as the next digit in the result. 
Result so far: 55684.0
The remainder is 203 after subtracting 2036 from 2239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Going ahead to step 9:
509 can be fit into 2030 3 times, resulting in a remainder of 503.
Use 3 as the next digit of our solution. 
Result so far: 55684.3
The remainder is 503 after subtracting 1527 from 2030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Step 10:
If we divide 5030 by 509, we get 9 and a remainder of 449.
Record the quotient 9 as the next digit in the result. 
Result so far: 55684.39
If we subtract 4581 from 5030, we get 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Moving on to step 11:
4490 divided by 509 is 8 with a remainder of 418.
Record the quotient 8 as the next digit in the result. 
Result so far: 55684.398
The remainder is 418 after subtracting 4072 from 4490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Let's proceed to step 12:
509 goes into 4180 8 times with a remainder of 108.
Use 8 as the next digit of our solution. 
Result so far: 55684.3988
If we subtract 4072 from 4180, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The quotient of the division is 55684.3988, and the remainder is 0.00108.
