65105379 ÷ 256 
We're looking to find how many times 256 goes into 65105379.

Going ahead to step 1:
The number 256 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 256

On to step 2:
65 divided by 256 is 0 with a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 65 after subtracting 0 from 65.
Fetch the next digit (1) from the dividend, attach it to 65 and continue: 651 / 256

Going ahead to step 3:
256 goes into 651 2 times with a remainder of 139.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 512 from 651 leaves us with 139.
Bring next digit (0) of the dividend behind the 139 and repeat the process: 1390 / 256

Going ahead to step 4:
256 goes into 1390 5 times with a remainder of 110.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtracting 1280 from 1390 leaves us with 110.
Take the next digit (5) from the dividend and append it to 110, then repeat: 1105 / 256

Advancing to step 5:
When dividing 1105 by 256, we get 4 with a remainder of 81.
Put 4 as the next digit of the answer. 
Result so far: 254.0
If we take 1024 away from 1105, we end up with 81.
Fetch the next digit (3) from the dividend, attach it to 81 and continue: 813 / 256

Step 6:
256 can be fit into 813 3 times, resulting in a remainder of 45.
The number 3 becomes the next digit in our result. 
Result so far: 2543.0
Subtract 768 from 813 to get 45.
Append the next digit (7) from the dividend to 45 and continue with: 457 / 256

Advancing to step 7:
If we divide 457 by 256, we get 1 and a remainder of 201.
The number 1 becomes the next digit in our result. 
Result so far: 25431.0
Subtract 256 from 457 to get 201.
Include the next digit (9) from the dividend after 201, then repeat: 2019 / 256

Moving on to step 8:
256 can be fit into 2019 7 times, resulting in a remainder of 227.
Record the quotient 7 as the next digit in the result. 
Result so far: 254317.0
Subtracting 1792 from 2019 leaves us with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Moving on to step 9:
256 can be fit into 2270 8 times, resulting in a remainder of 222.
The number 8 becomes the next digit in our result. 
Result so far: 254317.8
Deduct 2048 from 2270 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Step 10:
If we divide 2220 by 256, we get 8 and a remainder of 172.
Write down 8 as next digit of the result. 
Result so far: 254317.88
The remainder is 172 after subtracting 2048 from 2220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

The quotient of the division is 254317.88, and the remainder is 0.172.
