512490 ÷ 16 
We're looking to find how many times 16 goes into 512490.

On to step 1:
5 divided by 16 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 16

Going ahead to step 2:
The number 16 fits into 51 3 times, leaving a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 48 from 51 and we're left with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 16

On to step 3:
The number 16 fits into 32 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 32.0
If we subtract 32 from 32, we get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 16

Step 4:
4 divided by 16 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 320.0
Subtract 0 from 4 to get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 16

Advancing to step 5:
16 can be fit into 49 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 3203.0
Subtracting 48 from 49 leaves us with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 16

Step 6:
When dividing 10 by 16, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 32030.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
16 can be fit into 100 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 32030.6
The remainder is 4 after subtracting 96 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
16 can be fit into 40 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 32030.62
If we take 32 away from 40, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
If we divide 80 by 16, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 32030.625
If we subtract 80 from 80, 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.

Going ahead to step 10:
If we divide 0 by 16, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 32030.625
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.

Advancing to step 11:
When dividing 0 by 16, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 32030.625
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.

In conclusion, the division gives 32030.625 with a balance of 0.0.
