We divide 515992 by 16
The aim is to understand the frequency of 16 in 515992.

On to step 1:
If we divide 5 by 16, we get 0 and 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.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 16

Advancing to step 2:
The number 16 fits into 51 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 3 after subtracting 48 from 51.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 16

Going ahead to step 3:
16 can be fit into 35 2 times, resulting in a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 32.0
The remainder is 3 after subtracting 32 from 35.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 16

Going ahead to step 4:
The number 16 fits into 39 2 times, leaving a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 322.0
The remainder is 7 after subtracting 32 from 39.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 16

On to step 5:
If we divide 79 by 16, we get 4 and a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 3224.0
If we take 64 away from 79, we end up with 15.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 16

Advancing to step 6:
When dividing 152 by 16, we get 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 32249.0
The remainder is 8 after subtracting 144 from 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
The number 16 fits into 80 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 32249.5
Subtract 80 from 80 to 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.

Let's proceed to step 8:
The number 16 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 32249.5
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:
16 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 32249.5
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.

After the division, we end up with 32249.5 and a remainder of 0.0.
