Let's divide 80306265 by 256
Our goal is to divide 80306265 by 256.

On to step 1:
256 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 256

Moving on to step 2:
256 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
Deduct 0 from 80 and we're left with 80.
Take the next digit (3) from the dividend and append it to 80, then repeat: 803 / 256

On to step 3:
803 divided by 256 is 3 with a remainder of 35.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 768 from 803 and we're left with 35.
Take the next digit (0) from the dividend and append it to 35, then repeat: 350 / 256

Moving on to step 4:
256 can be fit into 350 1 times, resulting in a remainder of 94.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtract 256 from 350 to get 94.
Bring next digit (6) of the dividend behind the 94 and repeat the process: 946 / 256

Advancing to step 5:
If we divide 946 by 256, we get 3 and a remainder of 178.
Use 3 as the next digit of our solution. 
Result so far: 313.0
If we subtract 768 from 946, we get 178.
Fetch the next digit (2) from the dividend, attach it to 178 and continue: 1782 / 256

Moving on to step 6:
1782 divided by 256 is 6 with a remainder of 246.
The next digit of our result is 6. 
Result so far: 3136.0
Deduct 1536 from 1782 and we're left with 246.
Include the next digit (6) from the dividend after 246, then repeat: 2466 / 256

Going ahead to step 7:
When dividing 2466 by 256, we get 9 with a remainder of 162.
The next digit of our result is 9. 
Result so far: 31369.0
If we take 2304 away from 2466, we end up with 162.
Include the next digit (5) from the dividend after 162, then repeat: 1625 / 256

Going ahead to step 8:
If we divide 1625 by 256, we get 6 and a remainder of 89.
Write down 6 as next digit of the result. 
Result so far: 313696.0
If we take 1536 away from 1625, we end up with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 9:
When dividing 890 by 256, we get 3 with a remainder of 122.
Use 3 as the next digit of our solution. 
Result so far: 313696.3
Deduct 768 from 890 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 10:
When dividing 1220 by 256, we get 4 with a remainder of 196.
The next digit of our result is 4. 
Result so far: 313696.34
Subtract 1024 from 1220 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 11:
256 goes into 1960 7 times with a remainder of 168.
The next digit of our result is 7. 
Result so far: 313696.347
If we take 1792 away from 1960, we end up 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.

Let's proceed to step 12:
If we divide 1680 by 256, we get 6 and a remainder of 144.
Put 6 as the next digit of the answer. 
Result so far: 313696.3476
If we subtract 1536 from 1680, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 13:
256 goes into 1440 5 times with a remainder of 160.
Use 5 as the next digit of our solution. 
Result so far: 313696.34765
Subtract 1280 from 1440 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 14:
256 goes into 1600 6 times with a remainder of 64.
The next digit of our result is 6. 
Result so far: 313696.347656
If we take 1536 away from 1600, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 15:
The number 256 fits into 640 2 times, leaving a remainder of 128.
Put 2 as the next digit of the answer. 
Result so far: 313696.3476562
Deduct 512 from 640 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 16:
256 goes into 1280 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 313696.34765625
If we subtract 1280 from 1280, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 313696.34765625, and the remainder is 0.0.
