203454 divided by 16 
The aim is to understand the frequency of 16 in 203454.

On to step 1:
If we divide 2 by 16, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 16

Going ahead to step 2:
20 divided by 16 is 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 16 from 20 leaves us with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 16

Going ahead to step 3:
16 goes into 43 2 times with a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 32 away from 43, we end up with 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 16

Let's proceed to step 4:
16 can be fit into 114 7 times, resulting in a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 127.0
If we take 112 away from 114, we end up with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 16

Step 5:
The number 16 fits into 25 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1271.0
Subtracting 16 from 25 leaves us with 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 16

Going ahead to step 6:
The number 16 fits into 94 5 times, leaving a remainder of 14.
The next digit of our result is 5. 
Result so far: 12715.0
Deduct 80 from 94 and we're left 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.

Advancing to step 7:
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: 12715.8
Deduct 128 from 140 and we're left 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.

Step 8:
The number 16 fits into 120 7 times, leaving a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 12715.87
If we subtract 112 from 120, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
If we divide 80 by 16, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 12715.875
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.

Moving on to step 10:
16 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12715.875
If we take 0 away from 0, 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.

On to step 11:
If we divide 0 by 16, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 12715.875
If we take 0 away from 0, 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.

The quotient of the division is 12715.875, and the remainder is 0.0.
