411969 ÷ 16 
The aim is to understand the frequency of 16 in 411969.

On to step 1:
The number 16 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 16

On to step 2:
16 can be fit into 41 2 times, resulting in a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 32 from 41, we get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 16

Going ahead to step 3:
When dividing 91 by 16, we get 5 with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtracting 80 from 91 leaves us with 11.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 16

Going ahead to step 4:
When dividing 119 by 16, we get 7 with a remainder of 7.
The next digit of our result is 7. 
Result so far: 257.0
If we take 112 away from 119, we end up with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 16

Step 5:
76 divided by 16 is 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 2574.0
Subtract 64 from 76 to get 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 16

Let's proceed to step 6:
When dividing 129 by 16, we get 8 with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 25748.0
The remainder is 1 after subtracting 128 from 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
When dividing 10 by 16, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 25748.0
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.

Moving on to step 8:
When dividing 100 by 16, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 25748.06
If we take 96 away from 100, we end up 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.

Going ahead to step 9:
16 can be fit into 40 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 25748.062
Deduct 32 from 40 and we're left 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.

Let's proceed 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: 25748.0625
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.

Going ahead to step 11:
The number 16 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 25748.0625
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.

On to step 12:
16 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 25748.0625
Subtract 0 from 0 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.

The final result is 25748.0625 with a remainder of 0.0.
