720029 ÷ 16 
The aim is to understand the frequency of 16 in 720029.

Let's proceed to step 1:
When dividing 7 by 16, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 16

Let's proceed to step 2:
16 can be fit into 72 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 64 from 72 to get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 16

Step 3:
16 can be fit into 80 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 45.0
The remainder is 0 after subtracting 80 from 80.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 16

Step 4:
16 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 450.0
If we take 0 away from 0, we end up with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 16

Step 5:
2 divided by 16 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 4500.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 16

Step 6:
16 goes into 29 1 times with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 45001.0
Subtract 16 from 29 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
When dividing 130 by 16, we get 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 45001.8
If we take 128 away from 130, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
If we divide 20 by 16, we get 1 and a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 45001.81
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:
40 divided by 16 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 45001.812
If we take 32 away from 40, we end up 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.

Going ahead to step 10:
The number 16 fits into 80 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 45001.8125
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.

Advancing to step 11:
0 divided by 16 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 45001.8125
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.
Use 0 as the next digit of our solution. 
Result so far: 45001.8125
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 45001.8125, with a leftover of 0.0.
