Let's divide 12592223 by 255
We're looking to find how many times 255 goes into 12592223.

Step 1:
1 divided by 255 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 255

Advancing to step 2:
255 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 255

On to step 3:
255 goes into 125 0 times with a remainder of 125.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 125 to get 125.
Take the next digit (9) from the dividend and append it to 125, then repeat: 1259 / 255

Advancing to step 4:
1259 divided by 255 is 4 with a remainder of 239.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 1020 away from 1259, we end up with 239.
Grab the next digit (2) from the dividend, add it to 239, then carry on: 2392 / 255

Let's proceed to step 5:
When dividing 2392 by 255, we get 9 with a remainder of 97.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
Deduct 2295 from 2392 and we're left with 97.
Append the next digit (2) from the dividend to 97 and continue with: 972 / 255

Let's proceed to step 6:
255 can be fit into 972 3 times, resulting in a remainder of 207.
Use 3 as the next digit of our solution. 
Result so far: 493.0
The remainder is 207 after subtracting 765 from 972.
Take the next digit (2) from the dividend and append it to 207, then repeat: 2072 / 255

Let's proceed to step 7:
255 goes into 2072 8 times with a remainder of 32.
The next digit of our result is 8. 
Result so far: 4938.0
The remainder is 32 after subtracting 2040 from 2072.
Fetch the next digit (3) from the dividend, attach it to 32 and continue: 323 / 255

On to step 8:
The number 255 fits into 323 1 times, leaving a remainder of 68.
Use 1 as the next digit of our solution. 
Result so far: 49381.0
If we take 255 away from 323, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 9:
If we divide 680 by 255, we get 2 and a remainder of 170.
Record the quotient 2 as the next digit in the result. 
Result so far: 49381.2
Deduct 510 from 680 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 10:
255 can be fit into 1700 6 times, resulting in a remainder of 170.
The next digit of our result is 6. 
Result so far: 49381.26
The remainder is 170 after subtracting 1530 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 11:
If we divide 1700 by 255, we get 6 and a remainder of 170.
Record the quotient 6 as the next digit in the result. 
Result so far: 49381.266
Deduct 1530 from 1700 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

The final result is 49381.266 with a remainder of 0.017.
