We're dividing 403122 by 50 
Let's see how many times 50 fits into 403122.

Going ahead to step 1:
50 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 50

Moving on to step 2:
If we divide 40 by 50, we get 0 and 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.
Take the next digit (3) from the dividend and append it to 40, then repeat: 403 / 50

Step 3:
50 can be fit into 403 8 times, resulting in a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 400 from 403 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 50

Step 4:
When dividing 31 by 50, we get 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 80.0
The remainder is 31 after subtracting 0 from 31.
Include the next digit (2) from the dividend after 31, then repeat: 312 / 50

Going ahead to step 5:
312 divided by 50 is 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 806.0
If we take 300 away from 312, we end up with 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 50

Going ahead to step 6:
50 can be fit into 122 2 times, resulting in a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 8062.0
If we subtract 100 from 122, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
When dividing 220 by 50, we get 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 8062.4
Deduct 200 from 220 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
200 divided by 50 is 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 8062.44
If we subtract 200 from 200, we get 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 quotient of the division is 8062.44, and the remainder is 0.0.
