Let's divide 54165569 by 256
We want to divide 54165569 by 256.

Advancing to step 1:
The number 256 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 256

On to step 2:
If we divide 54 by 256, we get 0 and a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Fetch the next digit (1) from the dividend, attach it to 54 and continue: 541 / 256

Advancing to step 3:
256 can be fit into 541 2 times, resulting in a remainder of 29.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 512 from 541, we get 29.
Fetch the next digit (6) from the dividend, attach it to 29 and continue: 296 / 256

Step 4:
296 divided by 256 is 1 with a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 256 from 296, we get 40.
Append the next digit (5) from the dividend to 40 and continue with: 405 / 256

Going ahead to step 5:
256 goes into 405 1 times with a remainder of 149.
Write down 1 as next digit of the result. 
Result so far: 211.0
Deduct 256 from 405 and we're left with 149.
Include the next digit (5) from the dividend after 149, then repeat: 1495 / 256

Advancing to step 6:
When dividing 1495 by 256, we get 5 with a remainder of 215.
The number 5 becomes the next digit in our result. 
Result so far: 2115.0
Subtracting 1280 from 1495 leaves us with 215.
Bring next digit (6) of the dividend behind the 215 and repeat the process: 2156 / 256

On to step 7:
256 goes into 2156 8 times with a remainder of 108.
Use 8 as the next digit of our solution. 
Result so far: 21158.0
If we subtract 2048 from 2156, we get 108.
Take the next digit (9) from the dividend and append it to 108, then repeat: 1089 / 256

Let's proceed to step 8:
If we divide 1089 by 256, we get 4 and a remainder of 65.
Use 4 as the next digit of our solution. 
Result so far: 211584.0
Subtract 1024 from 1089 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 9:
If we divide 650 by 256, we get 2 and a remainder of 138.
Put 2 as the next digit of the answer. 
Result so far: 211584.2
Subtract 512 from 650 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Step 10:
If we divide 1380 by 256, we get 5 and a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 211584.25
Deduct 1280 from 1380 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 11:
When dividing 1000 by 256, we get 3 with a remainder of 232.
Use 3 as the next digit of our solution. 
Result so far: 211584.253
If we subtract 768 from 1000, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 12:
256 goes into 2320 9 times with a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 211584.2539
If we subtract 2304 from 2320, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
When dividing 160 by 256, we get 0 with a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 211584.2539
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 14:
The number 256 fits into 1600 6 times, leaving a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 211584.253906
Subtract 1536 from 1600 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 15:
The number 256 fits into 640 2 times, leaving a remainder of 128.
Write down 2 as next digit of the result. 
Result so far: 211584.2539062
Subtract 512 from 640 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 16:
1280 divided by 256 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 211584.25390625
Deduct 1280 from 1280 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 211584.25390625 with a balance of 0.0.
