We look at the division of 280636 by 51 
Our goal is to divide 280636 by 51.

Going ahead to step 1:
The number 51 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 51

Advancing to step 2:
51 can be fit into 28 0 times, resulting in a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Include the next digit (0) from the dividend after 28, then repeat: 280 / 51

On to step 3:
51 goes into 280 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 25 after subtracting 255 from 280.
Bring next digit (6) of the dividend behind the 25 and repeat the process: 256 / 51

Advancing to step 4:
51 goes into 256 5 times with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 55.0
Subtract 255 from 256 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 51

Let's proceed to step 5:
The number 51 fits into 13 0 times, leaving a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 550.0
The remainder is 13 after subtracting 0 from 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 51

On to step 6:
51 can be fit into 136 2 times, resulting in a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 5502.0
Deduct 102 from 136 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 7:
51 can be fit into 340 6 times, resulting in a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 5502.6
If we take 306 away from 340, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 8:
The number 51 fits into 340 6 times, leaving a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 5502.66
Deduct 306 from 340 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Our division results in 5502.66 with a remaining 0.034.
