We're dividing 505921 by 16 
We're looking to find how many times 16 goes into 505921.

Moving 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
The remainder is 5 after subtracting 0 from 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 16

Moving on to step 2:
The number 16 fits into 50 3 times, leaving a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 48 from 50 and we're left with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 16

Step 3:
25 divided by 16 is 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 31.0
If we subtract 16 from 25, we get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 16

Moving on to step 4:
The number 16 fits into 99 6 times, leaving a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 316.0
If we take 96 away from 99, we end up with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 16

Advancing to step 5:
16 can be fit into 32 2 times, resulting in a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 3162.0
If we take 32 away from 32, we end up with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 16

On to step 6:
16 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 31620.0
Deduct 0 from 1 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
10 divided by 16 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 31620.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
16 can be fit into 100 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 31620.06
Deduct 96 from 100 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
When dividing 40 by 16, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 31620.062
The remainder is 8 after subtracting 32 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
If we divide 80 by 16, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 31620.0625
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 11:
16 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 31620.0625
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 12:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 31620.0625
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.

The final result is 31620.0625 with a remainder of 0.0.
