Let's divide 921020 by 16
The aim is to understand the frequency of 16 in 921020.

Let's proceed to step 1:
When dividing 9 by 16, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 16

Going ahead to step 2:
16 goes into 92 5 times with a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 80 from 92, we get 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 16

Moving on to step 3:
121 divided by 16 is 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 57.0
If we subtract 112 from 121, we get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 16

Step 4:
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: 575.0
Subtracting 80 from 90 leaves us with 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 16

Advancing to step 5:
If we divide 102 by 16, we get 6 and a remainder of 6.
The next digit of our result is 6. 
Result so far: 5756.0
Subtract 96 from 102 to get 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 16

Step 6:
If we divide 60 by 16, we get 3 and a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 57563.0
If we subtract 48 from 60, we 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 7:
If we divide 120 by 16, we get 7 and a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 57563.7
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.

On to step 8:
16 can be fit into 80 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 57563.75
Subtract 80 from 80 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.

On to step 9:
16 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 57563.75
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.

Step 10:
16 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 57563.75
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.

After the division, we end up with 57563.75 and a remainder of 0.0.
