We divide 810267 by 51
Let's see how many times 51 fits into 810267.

Moving on to step 1:
51 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 51

Step 2:
If we divide 81 by 51, we get 1 and a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 30 after subtracting 51 from 81.
Bring next digit (0) of the dividend behind the 30 and repeat the process: 300 / 51

On to step 3:
If we divide 300 by 51, we get 5 and a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 255 from 300 leaves us with 45.
Include the next digit (2) from the dividend after 45, then repeat: 452 / 51

Let's proceed to step 4:
51 goes into 452 8 times with a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 158.0
Subtract 408 from 452 to get 44.
Bring next digit (6) of the dividend behind the 44 and repeat the process: 446 / 51

Going ahead to step 5:
If we divide 446 by 51, we get 8 and a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 1588.0
If we subtract 408 from 446, we get 38.
Take the next digit (7) from the dividend and append it to 38, then repeat: 387 / 51

On to step 6:
51 can be fit into 387 7 times, resulting in a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 15887.0
The remainder is 30 after subtracting 357 from 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
51 goes into 300 5 times with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 15887.5
If we take 255 away from 300, we end up 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.

Going ahead to step 8:
51 goes into 450 8 times with a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 15887.58
Subtracting 408 from 450 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 9:
51 goes into 420 8 times with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 15887.588
Deduct 408 from 420 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 15887.588, and the remainder is 0.0012.
