We look at the division of 12427489 by 255 
Our goal is to divide 12427489 by 255.

On to step 1:
255 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 255

Moving on to step 2:
The number 255 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 255

Moving on to step 3:
255 goes into 124 0 times with a remainder of 124.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 124, we get 124.
Take the next digit (2) from the dividend and append it to 124, then repeat: 1242 / 255

Let's proceed to step 4:
When dividing 1242 by 255, we get 4 with a remainder of 222.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 222 after subtracting 1020 from 1242.
Grab the next digit (7) from the dividend, add it to 222, then carry on: 2227 / 255

Step 5:
The number 255 fits into 2227 8 times, leaving a remainder of 187.
Write down 8 as next digit of the result. 
Result so far: 48.0
If we take 2040 away from 2227, we end up with 187.
Append the next digit (4) from the dividend to 187 and continue with: 1874 / 255

Advancing to step 6:
The number 255 fits into 1874 7 times, leaving a remainder of 89.
Use 7 as the next digit of our solution. 
Result so far: 487.0
Deduct 1785 from 1874 and we're left with 89.
Bring next digit (8) of the dividend behind the 89 and repeat the process: 898 / 255

Step 7:
If we divide 898 by 255, we get 3 and a remainder of 133.
The number 3 becomes the next digit in our result. 
Result so far: 4873.0
If we take 765 away from 898, we end up with 133.
Include the next digit (9) from the dividend after 133, then repeat: 1339 / 255

Step 8:
The number 255 fits into 1339 5 times, leaving a remainder of 64.
Put 5 as the next digit of the answer. 
Result so far: 48735.0
If we subtract 1275 from 1339, we 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.

Moving on to step 9:
640 divided by 255 is 2 with a remainder of 130.
Record the quotient 2 as the next digit in the result. 
Result so far: 48735.2
Subtracting 510 from 640 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 10:
255 goes into 1300 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 48735.25
Deduct 1275 from 1300 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 11:
If we divide 250 by 255, we get 0 and a remainder of 250.
Write down 0 as next digit of the result. 
Result so far: 48735.25
If we subtract 0 from 250, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 12:
255 can be fit into 2500 9 times, resulting in a remainder of 205.
The next digit of our result is 9. 
Result so far: 48735.2509
Subtracting 2295 from 2500 leaves us with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Going ahead to step 13:
If we divide 2050 by 255, we get 8 and a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 48735.25098
Deduct 2040 from 2050 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
255 can be fit into 100 0 times, resulting in a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 48735.25098
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 15:
If we divide 1000 by 255, we get 3 and a remainder of 235.
Write down 3 as next digit of the result. 
Result so far: 48735.2509803
Deduct 765 from 1000 and we're left with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Let's proceed to step 16:
If we divide 2350 by 255, we get 9 and a remainder of 55.
Record the quotient 9 as the next digit in the result. 
Result so far: 48735.25098039
The remainder is 55 after subtracting 2295 from 2350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final result is 48735.25098039 with a remainder of 5.5e-08.
