Let's divide 109959 by 16
The aim is to understand the frequency of 16 in 109959.

Going ahead to step 1:
The number 16 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 16

Advancing to step 2:
The number 16 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 16

Going ahead to step 3:
16 goes into 109 6 times with a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 96 away from 109, we end up with 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 16

Advancing to step 4:
The number 16 fits into 139 8 times, leaving a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 68.0
If we take 128 away from 139, we end up with 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 16

Going ahead to step 5:
16 can be fit into 115 7 times, resulting in a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 687.0
If we subtract 112 from 115, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 16

Moving on to step 6:
If we divide 39 by 16, we get 2 and a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 6872.0
Deduct 32 from 39 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
70 divided by 16 is 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 6872.4
If we subtract 64 from 70, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
When dividing 60 by 16, we get 3 with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 6872.43
Subtracting 48 from 60 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
120 divided by 16 is 7 with a remainder of 8.
The next digit of our result is 7. 
Result so far: 6872.437
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.

Going ahead to step 10:
The number 16 fits into 80 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 6872.4375
The remainder is 0 after subtracting 80 from 80.
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: 6872.4375
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.

Let's proceed to step 12:
If we divide 0 by 16, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6872.4375
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 6872.4375 with a remaining 0.0.
