449703 divided by 16 
The aim is to understand the frequency of 16 in 449703.

Let's proceed to step 1:
If we divide 4 by 16, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 16

Moving on to step 2:
If we divide 44 by 16, we get 2 and a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 32 away from 44, we end up with 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 16

Going ahead to step 3:
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: 28.0
Subtract 128 from 129 to get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 16

Going ahead to step 4:
16 can be fit into 17 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 281.0
Deduct 16 from 17 and we're left with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 16

Advancing to step 5:
16 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 2810.0
Subtracting 0 from 10 leaves us with 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 16

Advancing to step 6:
If we divide 103 by 16, we get 6 and a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 28106.0
If we subtract 96 from 103, we get 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.
Use 4 as the next digit of our solution. 
Result so far: 28106.4
If we take 64 away from 70, we end up with 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:
16 can be fit into 60 3 times, resulting in a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 28106.43
Subtract 48 from 60 to 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:
16 goes into 120 7 times with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 28106.437
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
16 goes into 80 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 28106.4375
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.

Advancing to step 11:
When dividing 0 by 16, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 28106.4375
Deduct 0 from 0 and we're left 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:
When dividing 0 by 16, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 28106.4375
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 28106.4375 with a remaining 0.0.
