519399 ÷ 50 
We're looking to find how many times 50 goes into 519399.

On 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
If we subtract 0 from 5, we get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 50

Let's proceed to step 2:
50 can be fit into 51 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 50 from 51 and we're left with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 50

Step 3:
19 divided by 50 is 0 with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 19 after subtracting 0 from 19.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 50

Let's proceed to step 4:
50 can be fit into 193 3 times, resulting in a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
If we take 150 away from 193, we end up with 43.
Append the next digit (9) from the dividend to 43 and continue with: 439 / 50

Let's proceed to step 5:
If we divide 439 by 50, we get 8 and a remainder of 39.
The number 8 becomes the next digit in our result. 
Result so far: 1038.0
Deduct 400 from 439 and we're left with 39.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 50

On to step 6:
If we divide 399 by 50, we get 7 and a remainder of 49.
Use 7 as the next digit of our solution. 
Result so far: 10387.0
Subtract 350 from 399 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 7:
The number 50 fits into 490 9 times, leaving a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 10387.9
If we take 450 away from 490, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
400 divided by 50 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 10387.98
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.

Let's proceed to step 9:
0 divided by 50 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10387.98
Subtracting 0 from 0 leaves us 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.

Step 10:
When dividing 0 by 50, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10387.98
If we subtract 0 from 0, 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.

In conclusion, the division gives 10387.98 with a balance of 0.0.
