We look at the division of 409785 by 51 
We're looking to find how many times 51 goes into 409785.

Moving on to step 1:
51 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 51

Let's proceed to step 2:
51 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Append the next digit (9) from the dividend to 40 and continue with: 409 / 51

Advancing to step 3:
The number 51 fits into 409 8 times, leaving a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 408 from 409 leaves us with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 51

Moving on to step 4:
The number 51 fits into 17 0 times, leaving a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
Subtracting 0 from 17 leaves us with 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 51

Moving on to step 5:
The number 51 fits into 178 3 times, leaving a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 803.0
If we subtract 153 from 178, we get 25.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 51

Step 6:
51 can be fit into 255 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 8035.0
Deduct 255 from 255 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
If we divide 0 by 51, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8035.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 51 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8035.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 8035.0 with a remainder of 0.0.
