207429 divided by 255 
We're looking to find how many times 255 goes into 207429.

Step 1:
The number 255 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 255

On to step 2:
20 divided by 255 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 255

Going ahead to step 3:
If we divide 207 by 255, we get 0 and a remainder of 207.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 207 leaves us with 207.
Include the next digit (4) from the dividend after 207, then repeat: 2074 / 255

Moving on to step 4:
When dividing 2074 by 255, we get 8 with a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 2040 from 2074, we get 34.
Bring next digit (2) of the dividend behind the 34 and repeat the process: 342 / 255

Going ahead to step 5:
If we divide 342 by 255, we get 1 and a remainder of 87.
Put 1 as the next digit of the answer. 
Result so far: 81.0
Deduct 255 from 342 and we're left with 87.
Take the next digit (9) from the dividend and append it to 87, then repeat: 879 / 255

Let's proceed to step 6:
If we divide 879 by 255, we get 3 and a remainder of 114.
The number 3 becomes the next digit in our result. 
Result so far: 813.0
If we subtract 765 from 879, we get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 7:
255 goes into 1140 4 times with a remainder of 120.
Record the quotient 4 as the next digit in the result. 
Result so far: 813.4
The remainder is 120 after subtracting 1020 from 1140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 8:
When dividing 1200 by 255, we get 4 with a remainder of 180.
Put 4 as the next digit of the answer. 
Result so far: 813.44
If we take 1020 away from 1200, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The final outcome is 813.44, with a leftover of 0.18.
