We're dividing 71426900 by 16 
The aim is to understand the frequency of 16 in 71426900.

Let's proceed to step 1:
16 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 16

Step 2:
16 can be fit into 71 4 times, resulting in a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 64 from 71 and we're left with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 16

Step 3:
16 goes into 74 4 times with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 44.0
If we subtract 64 from 74, we get 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 16

Moving on to step 4:
102 divided by 16 is 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 446.0
Subtracting 96 from 102 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 16

Going ahead to step 5:
16 can be fit into 66 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 4464.0
Subtract 64 from 66 to get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 16

Step 6:
16 goes into 29 1 times with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 44641.0
Deduct 16 from 29 and we're left with 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 16

Let's proceed to step 7:
The number 16 fits into 130 8 times, leaving a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 446418.0
Deduct 128 from 130 and we're left with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 16

Let's proceed to step 8:
When dividing 20 by 16, we get 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 4464181.0
Subtract 16 from 20 to 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:
When dividing 40 by 16, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 4464181.2
If we subtract 32 from 40, we 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.

Going ahead 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: 4464181.25
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.

Let's proceed to step 11:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4464181.25
Subtracting 0 from 0 leaves us 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:
If we divide 0 by 16, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4464181.25
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.

The final outcome is 4464181.25, with a leftover of 0.0.
