We look at the division of 38678353 by 256 
We want to divide 38678353 by 256.

Step 1:
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: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 256

Moving on to step 2:
The number 256 fits into 38 0 times, leaving a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Include the next digit (6) from the dividend after 38, then repeat: 386 / 256

Going ahead to step 3:
If we divide 386 by 256, we get 1 and a remainder of 130.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 256 from 386 leaves us with 130.
Bring next digit (7) of the dividend behind the 130 and repeat the process: 1307 / 256

On to step 4:
When dividing 1307 by 256, we get 5 with a remainder of 27.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 1280 from 1307, we get 27.
Bring next digit (8) of the dividend behind the 27 and repeat the process: 278 / 256

Going ahead to step 5:
256 goes into 278 1 times with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 151.0
If we subtract 256 from 278, we get 22.
Grab the next digit (3) from the dividend, add it to 22, then carry on: 223 / 256

On to step 6:
The number 256 fits into 223 0 times, leaving a remainder of 223.
Record the quotient 0 as the next digit in the result. 
Result so far: 1510.0
Subtracting 0 from 223 leaves us with 223.
Append the next digit (5) from the dividend to 223 and continue with: 2235 / 256

Going ahead to step 7:
The number 256 fits into 2235 8 times, leaving a remainder of 187.
The next digit of our result is 8. 
Result so far: 15108.0
The remainder is 187 after subtracting 2048 from 2235.
Bring next digit (3) of the dividend behind the 187 and repeat the process: 1873 / 256

Let's proceed to step 8:
1873 divided by 256 is 7 with a remainder of 81.
The number 7 becomes the next digit in our result. 
Result so far: 151087.0
Subtracting 1792 from 1873 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 9:
256 goes into 810 3 times with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 151087.3
Subtracting 768 from 810 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 10:
420 divided by 256 is 1 with a remainder of 164.
The next digit of our result is 1. 
Result so far: 151087.31
If we subtract 256 from 420, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 11:
When dividing 1640 by 256, we get 6 with a remainder of 104.
Use 6 as the next digit of our solution. 
Result so far: 151087.316
Deduct 1536 from 1640 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 12:
1040 divided by 256 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 151087.3164
If we subtract 1024 from 1040, 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.

On to step 13:
256 can be fit into 160 0 times, resulting in a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 151087.3164
Subtracting 0 from 160 leaves us 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.

Advancing to step 14:
1600 divided by 256 is 6 with a remainder of 64.
The next digit of our result is 6. 
Result so far: 151087.316406
Deduct 1536 from 1600 and we're left 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.
The next digit of our result is 2. 
Result so far: 151087.3164062
The remainder is 128 after subtracting 512 from 640.
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:
If we divide 1280 by 256, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 151087.31640625
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.

After the division, we end up with 151087.31640625 and a remainder of 0.0.
