We're dividing 690209 by 16 
The aim is to understand the frequency of 16 in 690209.

Going ahead to step 1:
If we divide 6 by 16, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 16

Advancing to step 2:
69 divided by 16 is 4 with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 64 from 69 leaves us with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 16

Going ahead to step 3:
50 divided by 16 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 43.0
If we subtract 48 from 50, we get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 16

Step 4:
16 goes into 22 1 times with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 431.0
The remainder is 6 after subtracting 16 from 22.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 16

On to step 5:
16 goes into 60 3 times with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 4313.0
If we subtract 48 from 60, we get 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 16

Advancing to step 6:
129 divided by 16 is 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 43138.0
Subtracting 128 from 129 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
16 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 43138.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
100 divided by 16 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 43138.06
If we subtract 96 from 100, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
16 can be fit into 40 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 43138.062
Subtract 32 from 40 to 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.

Moving on to 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: 43138.0625
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.

Moving on to step 11:
If we divide 0 by 16, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 43138.0625
Subtract 0 from 0 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.

Advancing to step 12:
When dividing 0 by 16, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 43138.0625
Subtract 0 from 0 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.

Our division results in 43138.0625 with a remaining 0.0.
