906223 divided by 16 
The aim is to understand the frequency of 16 in 906223.

Moving on to step 1:
9 divided by 16 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 16

Going ahead to step 2:
If we divide 90 by 16, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 5.0
If we take 80 away from 90, we end up with 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 16

Step 3:
16 can be fit into 106 6 times, resulting in a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
Deduct 96 from 106 and we're left with 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 16

Step 4:
The number 16 fits into 102 6 times, leaving a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 566.0
If we take 96 away from 102, we end up with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 16

Going ahead to step 5:
The number 16 fits into 62 3 times, leaving a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 5663.0
The remainder is 14 after subtracting 48 from 62.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 16

Going ahead to step 6:
The number 16 fits into 143 8 times, leaving a remainder of 15.
The next digit of our result is 8. 
Result so far: 56638.0
Subtracting 128 from 143 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
16 goes into 150 9 times with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 56638.9
The remainder is 6 after subtracting 144 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
When dividing 60 by 16, we get 3 with a remainder of 12.
The next digit of our result is 3. 
Result so far: 56638.93
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.

Let's proceed to step 9:
16 can be fit into 120 7 times, resulting in a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 56638.937
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.

Step 10:
16 goes into 80 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 56638.9375
Deduct 80 from 80 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.

Going ahead 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: 56638.9375
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.

Advancing to step 12:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 56638.9375
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.

The final outcome is 56638.9375, with a leftover of 0.0.
