504390 divided by 50 
We're looking to find how many times 50 goes into 504390.

On to step 1:
5 divided by 50 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 50

Moving on to step 2:
The number 50 fits into 50 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 50 from 50 to get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 50

Moving on to step 3:
When dividing 4 by 50, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 4 to get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 50

On to step 4:
50 goes into 43 0 times with a remainder of 43.
The next digit of our result is 0. 
Result so far: 100.0
Subtracting 0 from 43 leaves us with 43.
Fetch the next digit (9) from the dividend, attach it to 43 and continue: 439 / 50

Advancing to step 5:
439 divided by 50 is 8 with a remainder of 39.
The next digit of our result is 8. 
Result so far: 1008.0
If we subtract 400 from 439, we get 39.
Fetch the next digit (0) from the dividend, attach it to 39 and continue: 390 / 50

Advancing to step 6:
50 goes into 390 7 times with a remainder of 40.
The next digit of our result is 7. 
Result so far: 10087.0
The remainder is 40 after subtracting 350 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 7:
If we divide 400 by 50, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 10087.8
If we take 400 away from 400, 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.

On to step 8:
When dividing 0 by 50, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10087.8
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
If we divide 0 by 50, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10087.8
Deduct 0 from 0 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.

The final result is 10087.8 with a remainder of 0.0.
