We're dividing 15142877 by 256 
Let's see how many times 256 fits into 15142877.

Going ahead to step 1:
The number 256 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 256

Let's proceed to step 2:
When dividing 15 by 256, we get 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 256

Going ahead to step 3:
151 divided by 256 is 0 with a remainder of 151.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 151 after subtracting 0 from 151.
Take the next digit (4) from the dividend and append it to 151, then repeat: 1514 / 256

Let's proceed to step 4:
256 can be fit into 1514 5 times, resulting in a remainder of 234.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 1280 away from 1514, we end up with 234.
Bring next digit (2) of the dividend behind the 234 and repeat the process: 2342 / 256

Step 5:
The number 256 fits into 2342 9 times, leaving a remainder of 38.
The next digit of our result is 9. 
Result so far: 59.0
Deduct 2304 from 2342 and we're left with 38.
Grab the next digit (8) from the dividend, add it to 38, then carry on: 388 / 256

On to step 6:
256 can be fit into 388 1 times, resulting in a remainder of 132.
Put 1 as the next digit of the answer. 
Result so far: 591.0
Deduct 256 from 388 and we're left with 132.
Include the next digit (7) from the dividend after 132, then repeat: 1327 / 256

Moving on to step 7:
256 can be fit into 1327 5 times, resulting in a remainder of 47.
Use 5 as the next digit of our solution. 
Result so far: 5915.0
Deduct 1280 from 1327 and we're left with 47.
Take the next digit (7) from the dividend and append it to 47, then repeat: 477 / 256

Moving on to step 8:
256 can be fit into 477 1 times, resulting in a remainder of 221.
Write down 1 as next digit of the result. 
Result so far: 59151.0
Subtracting 256 from 477 leaves us with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Advancing to step 9:
2210 divided by 256 is 8 with a remainder of 162.
Put 8 as the next digit of the answer. 
Result so far: 59151.8
If we take 2048 away from 2210, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Going ahead to step 10:
When dividing 1620 by 256, we get 6 with a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 59151.86
Deduct 1536 from 1620 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 11:
When dividing 840 by 256, we get 3 with a remainder of 72.
Write down 3 as next digit of the result. 
Result so far: 59151.863
Subtract 768 from 840 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 12:
256 goes into 720 2 times with a remainder of 208.
Write down 2 as next digit of the result. 
Result so far: 59151.8632
Subtract 512 from 720 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 13:
When dividing 2080 by 256, we get 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 59151.86328
The remainder is 32 after subtracting 2048 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 14:
If we divide 320 by 256, we get 1 and a remainder of 64.
Put 1 as the next digit of the answer. 
Result so far: 59151.863281
Subtract 256 from 320 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.

Let's proceed to step 15:
640 divided by 256 is 2 with a remainder of 128.
The number 2 becomes the next digit in our result. 
Result so far: 59151.8632812
Subtracting 512 from 640 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.

Going ahead to step 16:
When dividing 1280 by 256, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 59151.86328125
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.

The final result is 59151.86328125 with a remainder of 0.0.
