48643980 divided by 256 
Let's see how many times 256 fits into 48643980.

Advancing to step 1:
When dividing 4 by 256, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 256

On to step 2:
256 can be fit into 48 0 times, resulting in a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Grab the next digit (6) from the dividend, add it to 48, then carry on: 486 / 256

On to step 3:
256 goes into 486 1 times with a remainder of 230.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 256 from 486 leaves us with 230.
Grab the next digit (4) from the dividend, add it to 230, then carry on: 2304 / 256

Advancing to step 4:
If we divide 2304 by 256, we get 9 and a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we take 2304 away from 2304, we end up with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 256

Let's proceed to step 5:
If we divide 3 by 256, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 190.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 256

On to step 6:
When dividing 39 by 256, we get 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 1900.0
The remainder is 39 after subtracting 0 from 39.
Append the next digit (8) from the dividend to 39 and continue with: 398 / 256

Going ahead to step 7:
398 divided by 256 is 1 with a remainder of 142.
Write down 1 as next digit of the result. 
Result so far: 19001.0
Subtract 256 from 398 to get 142.
Bring next digit (0) of the dividend behind the 142 and repeat the process: 1420 / 256

On to step 8:
The number 256 fits into 1420 5 times, leaving a remainder of 140.
Write down 5 as next digit of the result. 
Result so far: 190015.0
Deduct 1280 from 1420 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 9:
The number 256 fits into 1400 5 times, leaving a remainder of 120.
The number 5 becomes the next digit in our result. 
Result so far: 190015.5
Deduct 1280 from 1400 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 10:
When dividing 1200 by 256, we get 4 with a remainder of 176.
Record the quotient 4 as the next digit in the result. 
Result so far: 190015.54
Deduct 1024 from 1200 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 11:
The number 256 fits into 1760 6 times, leaving a remainder of 224.
The number 6 becomes the next digit in our result. 
Result so far: 190015.546
Subtracting 1536 from 1760 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 12:
256 goes into 2240 8 times with a remainder of 192.
Put 8 as the next digit of the answer. 
Result so far: 190015.5468
The remainder is 192 after subtracting 2048 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 13:
If we divide 1920 by 256, we get 7 and a remainder of 128.
The next digit of our result is 7. 
Result so far: 190015.54687
Deduct 1792 from 1920 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.

On to step 14:
When dividing 1280 by 256, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 190015.546875
The remainder is 0 after subtracting 1280 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 15:
256 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 190015.546875
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 16:
256 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 190015.546875
Subtract 0 from 0 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.

The final result is 190015.546875 with a remainder of 0.0.
