We divide 218403 by 16
The aim is to understand the frequency of 16 in 218403.

Moving on to step 1:
16 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 16

On to step 2:
When dividing 21 by 16, we get 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 5 after subtracting 16 from 21.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 16

Moving on to step 3:
When dividing 58 by 16, we get 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 10 after subtracting 48 from 58.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 16

Going ahead to step 4:
16 can be fit into 104 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 136.0
If we subtract 96 from 104, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 16

Advancing to step 5:
When dividing 80 by 16, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1365.0
Deduct 80 from 80 and we're left with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 16

Going ahead to step 6:
When dividing 3 by 16, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 13650.0
Subtracting 0 from 3 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
When dividing 30 by 16, we get 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 13650.1
The remainder is 14 after subtracting 16 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
The number 16 fits into 140 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 13650.18
If we take 128 away from 140, we end up 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.

Going ahead 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: 13650.187
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 can be fit into 80 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 13650.1875
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.

On to step 11:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 13650.1875
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.

Let's proceed to step 12:
When dividing 0 by 16, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13650.1875
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.

The final outcome is 13650.1875, with a leftover of 0.0.
