Let's divide 80307623 by 509
Our goal is to divide 80307623 by 509.

Advancing to step 1:
8 divided by 509 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 509

Step 2:
If we divide 80 by 509, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Grab the next digit (3) from the dividend, add it to 80, then carry on: 803 / 509

Advancing to step 3:
803 divided by 509 is 1 with a remainder of 294.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 509 from 803 to get 294.
Grab the next digit (0) from the dividend, add it to 294, then carry on: 2940 / 509

On to step 4:
The number 509 fits into 2940 5 times, leaving a remainder of 395.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 2545 from 2940 to get 395.
Include the next digit (7) from the dividend after 395, then repeat: 3957 / 509

Advancing to step 5:
When dividing 3957 by 509, we get 7 with a remainder of 394.
Use 7 as the next digit of our solution. 
Result so far: 157.0
If we subtract 3563 from 3957, we get 394.
Fetch the next digit (6) from the dividend, attach it to 394 and continue: 3946 / 509

Step 6:
3946 divided by 509 is 7 with a remainder of 383.
Write down 7 as next digit of the result. 
Result so far: 1577.0
Subtract 3563 from 3946 to get 383.
Fetch the next digit (2) from the dividend, attach it to 383 and continue: 3832 / 509

On to step 7:
509 can be fit into 3832 7 times, resulting in a remainder of 269.
The next digit of our result is 7. 
Result so far: 15777.0
Subtract 3563 from 3832 to get 269.
Append the next digit (3) from the dividend to 269 and continue with: 2693 / 509

Advancing to step 8:
If we divide 2693 by 509, we get 5 and a remainder of 148.
Put 5 as the next digit of the answer. 
Result so far: 157775.0
Subtracting 2545 from 2693 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 9:
When dividing 1480 by 509, we get 2 with a remainder of 462.
The next digit of our result is 2. 
Result so far: 157775.2
If we take 1018 away from 1480, we end up with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Moving on to step 10:
509 goes into 4620 9 times with a remainder of 39.
The next digit of our result is 9. 
Result so far: 157775.29
If we take 4581 away from 4620, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 11:
The number 509 fits into 390 0 times, leaving a remainder of 390.
Put 0 as the next digit of the answer. 
Result so far: 157775.29
Subtracting 0 from 390 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 12:
If we divide 3900 by 509, we get 7 and a remainder of 337.
Use 7 as the next digit of our solution. 
Result so far: 157775.2907
Deduct 3563 from 3900 and we're left with 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

On to step 13:
If we divide 3370 by 509, we get 6 and a remainder of 316.
The next digit of our result is 6. 
Result so far: 157775.29076
Deduct 3054 from 3370 and we're left with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 14:
The number 509 fits into 3160 6 times, leaving a remainder of 106.
The next digit of our result is 6. 
Result so far: 157775.290766
If we subtract 3054 from 3160, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

In conclusion, the division gives 157775.290766 with a balance of 1.06e-05.
