We look at the division of 31830093 by 255 
We want to divide 31830093 by 255.

On to step 1:
The number 255 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 255

Step 2:
If we divide 31 by 255, we get 0 and a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Append the next digit (8) from the dividend to 31 and continue with: 318 / 255

Step 3:
When dividing 318 by 255, we get 1 with a remainder of 63.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 255 from 318 and we're left with 63.
Take the next digit (3) from the dividend and append it to 63, then repeat: 633 / 255

On to step 4:
255 can be fit into 633 2 times, resulting in a remainder of 123.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 510 from 633 to get 123.
Grab the next digit (0) from the dividend, add it to 123, then carry on: 1230 / 255

Moving on to step 5:
255 can be fit into 1230 4 times, resulting in a remainder of 210.
Use 4 as the next digit of our solution. 
Result so far: 124.0
The remainder is 210 after subtracting 1020 from 1230.
Append the next digit (0) from the dividend to 210 and continue with: 2100 / 255

Moving on to step 6:
2100 divided by 255 is 8 with a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 1248.0
Deduct 2040 from 2100 and we're left with 60.
Bring next digit (9) of the dividend behind the 60 and repeat the process: 609 / 255

Let's proceed to step 7:
When dividing 609 by 255, we get 2 with a remainder of 99.
The next digit of our result is 2. 
Result so far: 12482.0
The remainder is 99 after subtracting 510 from 609.
Bring next digit (3) of the dividend behind the 99 and repeat the process: 993 / 255

Going ahead to step 8:
If we divide 993 by 255, we get 3 and a remainder of 228.
Put 3 as the next digit of the answer. 
Result so far: 124823.0
If we take 765 away from 993, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Step 9:
2280 divided by 255 is 8 with a remainder of 240.
Use 8 as the next digit of our solution. 
Result so far: 124823.8
Subtract 2040 from 2280 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 10:
255 can be fit into 2400 9 times, resulting in a remainder of 105.
The next digit of our result is 9. 
Result so far: 124823.89
Subtracting 2295 from 2400 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 11:
If we divide 1050 by 255, we get 4 and a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 124823.894
If we take 1020 away from 1050, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
When dividing 300 by 255, we get 1 with a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 124823.8941
Subtracting 255 from 300 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 13:
When dividing 450 by 255, we get 1 with a remainder of 195.
Put 1 as the next digit of the answer. 
Result so far: 124823.89411
Subtract 255 from 450 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

After the division, we end up with 124823.89411 and a remainder of 0.000195.
