We divide 521323 by 16
We want to figure out the number of times 521323 can be divided by 16.

Let's proceed to step 1:
The number 16 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 16

Advancing to step 2:
16 can be fit into 52 3 times, resulting in a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 4 after subtracting 48 from 52.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 16

Moving on to step 3:
16 goes into 41 2 times with a remainder of 9.
The next digit of our result is 2. 
Result so far: 32.0
The remainder is 9 after subtracting 32 from 41.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 16

Going ahead to step 4:
The number 16 fits into 93 5 times, leaving a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 325.0
The remainder is 13 after subtracting 80 from 93.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 16

Step 5:
16 goes into 132 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 3258.0
Subtract 128 from 132 to get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 16

Let's proceed to step 6:
43 divided by 16 is 2 with a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 32582.0
If we subtract 32 from 43, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
16 goes into 110 6 times with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 32582.6
If we take 96 away from 110, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
If we divide 140 by 16, we get 8 and a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 32582.68
If we subtract 128 from 140, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
When dividing 120 by 16, we get 7 with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 32582.687
Subtracting 112 from 120 leaves us 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.

Moving on to step 10:
80 divided by 16 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 32582.6875
If we take 80 away from 80, 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.

Step 11:
When dividing 0 by 16, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 32582.6875
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:
16 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 32582.6875
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.

The final outcome is 32582.6875, with a leftover of 0.0.
