Let's divide 80430315 by 756
Let's see how many times 756 fits into 80430315.

Going ahead to step 1:
756 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 756

Moving on to step 2:
756 goes into 80 0 times with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Include the next digit (4) from the dividend after 80, then repeat: 804 / 756

On to step 3:
The number 756 fits into 804 1 times, leaving a remainder of 48.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 756 from 804 leaves us with 48.
Include the next digit (3) from the dividend after 48, then repeat: 483 / 756

Advancing to step 4:
When dividing 483 by 756, we get 0 with a remainder of 483.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 483 and we're left with 483.
Include the next digit (0) from the dividend after 483, then repeat: 4830 / 756

Step 5:
If we divide 4830 by 756, we get 6 and a remainder of 294.
The number 6 becomes the next digit in our result. 
Result so far: 106.0
If we take 4536 away from 4830, we end up with 294.
Take the next digit (3) from the dividend and append it to 294, then repeat: 2943 / 756

Let's proceed to step 6:
The number 756 fits into 2943 3 times, leaving a remainder of 675.
Use 3 as the next digit of our solution. 
Result so far: 1063.0
The remainder is 675 after subtracting 2268 from 2943.
Grab the next digit (1) from the dividend, add it to 675, then carry on: 6751 / 756

On to step 7:
756 can be fit into 6751 8 times, resulting in a remainder of 703.
Use 8 as the next digit of our solution. 
Result so far: 10638.0
If we take 6048 away from 6751, we end up with 703.
Take the next digit (5) from the dividend and append it to 703, then repeat: 7035 / 756

Advancing to step 8:
The number 756 fits into 7035 9 times, leaving a remainder of 231.
Put 9 as the next digit of the answer. 
Result so far: 106389.0
The remainder is 231 after subtracting 6804 from 7035.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Step 9:
The number 756 fits into 2310 3 times, leaving a remainder of 42.
The next digit of our result is 3. 
Result so far: 106389.3
If we subtract 2268 from 2310, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 10:
The number 756 fits into 420 0 times, leaving a remainder of 420.
The number 0 becomes the next digit in our result. 
Result so far: 106389.3
If we subtract 0 from 420, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 11:
When dividing 4200 by 756, we get 5 with a remainder of 420.
Write down 5 as next digit of the result. 
Result so far: 106389.305
The remainder is 420 after subtracting 3780 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 12:
The number 756 fits into 4200 5 times, leaving a remainder of 420.
Use 5 as the next digit of our solution. 
Result so far: 106389.3055
If we subtract 3780 from 4200, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

The quotient of the division is 106389.3055, and the remainder is 0.0042.
