We look at the division of 742385 by 16 
The aim is to understand the frequency of 16 in 742385.

Step 1:
7 divided by 16 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 16

Advancing to step 2:
16 goes into 74 4 times with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 64 from 74 to get 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 16

Advancing to step 3:
The number 16 fits into 102 6 times, leaving a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 46.0
Subtracting 96 from 102 leaves us with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 16

On to step 4:
If we divide 63 by 16, we get 3 and a remainder of 15.
The next digit of our result is 3. 
Result so far: 463.0
The remainder is 15 after subtracting 48 from 63.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 16

Step 5:
When dividing 158 by 16, we get 9 with a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 4639.0
Subtract 144 from 158 to get 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 16

Advancing to step 6:
16 can be fit into 145 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 46399.0
If we take 144 away from 145, we end up 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:
10 divided by 16 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 46399.0
Deduct 0 from 10 and we're left with 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:
When dividing 100 by 16, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 46399.06
The remainder is 4 after subtracting 96 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
16 goes into 40 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 46399.062
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.

Advancing to step 10:
16 can be fit into 80 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 46399.0625
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.

Step 11:
If we divide 0 by 16, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 46399.0625
If we subtract 0 from 0, 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.

On to step 12:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 46399.0625
If we subtract 0 from 0, 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.

The quotient of the division is 46399.0625, and the remainder is 0.0.
