503942 divided by 50 
Let's see how many times 50 fits into 503942.

Advancing to step 1:
If we divide 5 by 50, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 50

Step 2:
When dividing 50 by 50, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 50 from 50 to get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 50

Step 3:
The number 50 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 50

Going ahead to step 4:
39 divided by 50 is 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
If we subtract 0 from 39, we get 39.
Take the next digit (4) from the dividend and append it to 39, then repeat: 394 / 50

Let's proceed to step 5:
50 can be fit into 394 7 times, resulting in a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 1007.0
Subtract 350 from 394 to get 44.
Bring next digit (2) of the dividend behind the 44 and repeat the process: 442 / 50

Going ahead to step 6:
442 divided by 50 is 8 with a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 10078.0
Subtracting 400 from 442 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 7:
50 can be fit into 420 8 times, resulting in a remainder of 20.
The next digit of our result is 8. 
Result so far: 10078.8
The remainder is 20 after subtracting 400 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
When dividing 200 by 50, we get 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 10078.84
Deduct 200 from 200 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.

Moving on to step 9:
0 divided by 50 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10078.84
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.

Advancing to step 10:
0 divided by 50 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10078.84
Subtract 0 from 0 to 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.

Our division results in 10078.84 with a remaining 0.0.
