We look at the division of 10009122 by 255 
Our goal is to divide 10009122 by 255.

Going ahead to step 1:
1 divided by 255 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 255

Advancing to step 2:
10 divided by 255 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 255

Moving on to step 3:
The number 255 fits into 100 0 times, leaving a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 100 leaves us with 100.
Take the next digit (0) from the dividend and append it to 100, then repeat: 1000 / 255

On to step 4:
The number 255 fits into 1000 3 times, leaving a remainder of 235.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 765 from 1000 to get 235.
Append the next digit (9) from the dividend to 235 and continue with: 2359 / 255

Going ahead to step 5:
2359 divided by 255 is 9 with a remainder of 64.
Use 9 as the next digit of our solution. 
Result so far: 39.0
The remainder is 64 after subtracting 2295 from 2359.
Include the next digit (1) from the dividend after 64, then repeat: 641 / 255

Let's proceed to step 6:
641 divided by 255 is 2 with a remainder of 131.
Write down 2 as next digit of the result. 
Result so far: 392.0
Subtracting 510 from 641 leaves us with 131.
Bring next digit (2) of the dividend behind the 131 and repeat the process: 1312 / 255

Advancing to step 7:
When dividing 1312 by 255, we get 5 with a remainder of 37.
Record the quotient 5 as the next digit in the result. 
Result so far: 3925.0
Subtract 1275 from 1312 to get 37.
Take the next digit (2) from the dividend and append it to 37, then repeat: 372 / 255

Moving on to step 8:
The number 255 fits into 372 1 times, leaving a remainder of 117.
The next digit of our result is 1. 
Result so far: 39251.0
Deduct 255 from 372 and we're left with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Moving on to step 9:
The number 255 fits into 1170 4 times, leaving a remainder of 150.
Use 4 as the next digit of our solution. 
Result so far: 39251.4
The remainder is 150 after subtracting 1020 from 1170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 10:
255 can be fit into 1500 5 times, resulting in a remainder of 225.
Record the quotient 5 as the next digit in the result. 
Result so far: 39251.45
If we subtract 1275 from 1500, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 11:
255 can be fit into 2250 8 times, resulting in a remainder of 210.
Put 8 as the next digit of the answer. 
Result so far: 39251.458
Subtract 2040 from 2250 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 12:
255 goes into 2100 8 times with a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 39251.4588
If we subtract 2040 from 2100, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 39251.4588 with a remainder of 0.0006.
