We're dividing 22980857 by 255 
Let's see how many times 255 fits into 22980857.

On to step 1:
255 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 255

Advancing to step 2:
If we divide 22 by 255, we get 0 and a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 22 to get 22.
Fetch the next digit (9) from the dividend, attach it to 22 and continue: 229 / 255

On to step 3:
If we divide 229 by 255, we get 0 and a remainder of 229.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 229 leaves us with 229.
Include the next digit (8) from the dividend after 229, then repeat: 2298 / 255

On to step 4:
255 goes into 2298 9 times with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 3 after subtracting 2295 from 2298.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 255

Step 5:
30 divided by 255 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 90.0
Subtracting 0 from 30 leaves us with 30.
Include the next digit (8) from the dividend after 30, then repeat: 308 / 255

On to step 6:
255 can be fit into 308 1 times, resulting in a remainder of 53.
The next digit of our result is 1. 
Result so far: 901.0
If we subtract 255 from 308, we get 53.
Fetch the next digit (5) from the dividend, attach it to 53 and continue: 535 / 255

Let's proceed to step 7:
535 divided by 255 is 2 with a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 9012.0
If we take 510 away from 535, we end up with 25.
Fetch the next digit (7) from the dividend, attach it to 25 and continue: 257 / 255

Going ahead to step 8:
255 goes into 257 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 90121.0
If we subtract 255 from 257, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
The number 255 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 90121.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
When dividing 200 by 255, we get 0 with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 90121.0
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 90121.0 and a remainder of 0.2.
