516490 ÷ 50 
We want to figure out the number of times 516490 can be divided by 50.

Step 1:
50 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 50

On to step 2:
50 goes into 51 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 1 after subtracting 50 from 51.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 50

Let's proceed to step 3:
16 divided by 50 is 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 16 to get 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 50

Step 4:
If we divide 164 by 50, we get 3 and a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 103.0
If we subtract 150 from 164, we get 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 50

Going ahead to step 5:
The number 50 fits into 149 2 times, leaving a remainder of 49.
The number 2 becomes the next digit in our result. 
Result so far: 1032.0
Deduct 100 from 149 and we're left with 49.
Take the next digit (0) from the dividend and append it to 49, then repeat: 490 / 50

On to step 6:
490 divided by 50 is 9 with a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 10329.0
The remainder is 40 after subtracting 450 from 490.
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 7:
If we divide 400 by 50, we get 8 and a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 10329.8
The remainder is 0 after subtracting 400 from 400.
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:
The number 50 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10329.8
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.

Let's proceed to step 9:
When dividing 0 by 50, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10329.8
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.

Our division results in 10329.8 with a remaining 0.0.
