Let's divide 87384932 by 509
We're looking to find how many times 509 goes into 87384932.

Advancing to step 1:
509 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 509

Step 2:
If we divide 87 by 509, we get 0 and a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Take the next digit (3) from the dividend and append it to 87, then repeat: 873 / 509

Step 3:
When dividing 873 by 509, we get 1 with a remainder of 364.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 509 from 873 leaves us with 364.
Bring next digit (8) of the dividend behind the 364 and repeat the process: 3648 / 509

Advancing to step 4:
If we divide 3648 by 509, we get 7 and a remainder of 85.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Deduct 3563 from 3648 and we're left with 85.
Fetch the next digit (4) from the dividend, attach it to 85 and continue: 854 / 509

Moving on to step 5:
854 divided by 509 is 1 with a remainder of 345.
Use 1 as the next digit of our solution. 
Result so far: 171.0
Deduct 509 from 854 and we're left with 345.
Grab the next digit (9) from the dividend, add it to 345, then carry on: 3459 / 509

Going ahead to step 6:
509 goes into 3459 6 times with a remainder of 405.
The next digit of our result is 6. 
Result so far: 1716.0
If we subtract 3054 from 3459, we get 405.
Take the next digit (3) from the dividend and append it to 405, then repeat: 4053 / 509

On to step 7:
509 goes into 4053 7 times with a remainder of 490.
Put 7 as the next digit of the answer. 
Result so far: 17167.0
Subtracting 3563 from 4053 leaves us with 490.
Bring next digit (2) of the dividend behind the 490 and repeat the process: 4902 / 509

Let's proceed to step 8:
If we divide 4902 by 509, we get 9 and a remainder of 321.
Put 9 as the next digit of the answer. 
Result so far: 171679.0
Deduct 4581 from 4902 and we're left with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Advancing to step 9:
3210 divided by 509 is 6 with a remainder of 156.
Use 6 as the next digit of our solution. 
Result so far: 171679.6
If we take 3054 away from 3210, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 10:
When dividing 1560 by 509, we get 3 with a remainder of 33.
The next digit of our result is 3. 
Result so far: 171679.63
The remainder is 33 after subtracting 1527 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 11:
The number 509 fits into 330 0 times, leaving a remainder of 330.
Write down 0 as next digit of the result. 
Result so far: 171679.63
Deduct 0 from 330 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 12:
3300 divided by 509 is 6 with a remainder of 246.
Put 6 as the next digit of the answer. 
Result so far: 171679.6306
Subtracting 3054 from 3300 leaves us with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

On to step 13:
509 can be fit into 2460 4 times, resulting in a remainder of 424.
The next digit of our result is 4. 
Result so far: 171679.63064
Subtracting 2036 from 2460 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Step 14:
509 can be fit into 4240 8 times, resulting in a remainder of 168.
Use 8 as the next digit of our solution. 
Result so far: 171679.630648
Deduct 4072 from 4240 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 15:
The number 509 fits into 1680 3 times, leaving a remainder of 153.
The number 3 becomes the next digit in our result. 
Result so far: 171679.6306483
If we take 1527 away from 1680, we end up with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Advancing to step 16:
The number 509 fits into 1530 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 171679.63064833
Deduct 1527 from 1530 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

In conclusion, the division gives 171679.63064833 with a balance of 3e-09.
