Let's divide 69628391 by 256
Our goal is to divide 69628391 by 256.

Step 1:
If we divide 6 by 256, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 256

Let's proceed to step 2:
When dividing 69 by 256, we get 0 with a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Bring next digit (6) of the dividend behind the 69 and repeat the process: 696 / 256

Step 3:
696 divided by 256 is 2 with a remainder of 184.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 512 from 696, we get 184.
Grab the next digit (2) from the dividend, add it to 184, then carry on: 1842 / 256

Step 4:
256 can be fit into 1842 7 times, resulting in a remainder of 50.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
If we subtract 1792 from 1842, we get 50.
Grab the next digit (8) from the dividend, add it to 50, then carry on: 508 / 256

On to step 5:
If we divide 508 by 256, we get 1 and a remainder of 252.
Use 1 as the next digit of our solution. 
Result so far: 271.0
Subtracting 256 from 508 leaves us with 252.
Take the next digit (3) from the dividend and append it to 252, then repeat: 2523 / 256

On to step 6:
256 goes into 2523 9 times with a remainder of 219.
The number 9 becomes the next digit in our result. 
Result so far: 2719.0
If we subtract 2304 from 2523, we get 219.
Include the next digit (9) from the dividend after 219, then repeat: 2199 / 256

Advancing to step 7:
2199 divided by 256 is 8 with a remainder of 151.
The next digit of our result is 8. 
Result so far: 27198.0
Subtracting 2048 from 2199 leaves us with 151.
Include the next digit (1) from the dividend after 151, then repeat: 1511 / 256

Moving on to step 8:
1511 divided by 256 is 5 with a remainder of 231.
Put 5 as the next digit of the answer. 
Result so far: 271985.0
Subtract 1280 from 1511 to get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Advancing to step 9:
The number 256 fits into 2310 9 times, leaving a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 271985.9
If we take 2304 away from 2310, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
When dividing 60 by 256, we get 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 271985.9
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
If we divide 600 by 256, we get 2 and a remainder of 88.
Put 2 as the next digit of the answer. 
Result so far: 271985.902
Subtracting 512 from 600 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 12:
When dividing 880 by 256, we get 3 with a remainder of 112.
Record the quotient 3 as the next digit in the result. 
Result so far: 271985.9023
Subtract 768 from 880 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 13:
256 can be fit into 1120 4 times, resulting in a remainder of 96.
Put 4 as the next digit of the answer. 
Result so far: 271985.90234
If we subtract 1024 from 1120, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 14:
If we divide 960 by 256, we get 3 and a remainder of 192.
Put 3 as the next digit of the answer. 
Result so far: 271985.902343
Subtracting 768 from 960 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 15:
256 goes into 1920 7 times with a remainder of 128.
Record the quotient 7 as the next digit in the result. 
Result so far: 271985.9023437
Subtracting 1792 from 1920 leaves us 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.

Moving on to step 16:
If we divide 1280 by 256, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 271985.90234375
Subtract 1280 from 1280 to 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.

After the division, we end up with 271985.90234375 and a remainder of 0.0.
