We look at the division of 738044 by 72 
The aim is to understand the frequency of 72 in 738044.

Let's proceed to step 1:
7 divided by 72 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 72

On to step 2:
The number 72 fits into 73 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 72 from 73, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 72

Moving on to step 3:
72 goes into 18 0 times with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 18 to get 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 72

Going ahead to step 4:
If we divide 180 by 72, we get 2 and a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 102.0
Deduct 144 from 180 and we're left with 36.
Include the next digit (4) from the dividend after 36, then repeat: 364 / 72

Advancing to step 5:
72 can be fit into 364 5 times, resulting in a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 1025.0
If we take 360 away from 364, we end up with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 72

On to step 6:
72 can be fit into 44 0 times, resulting in a remainder of 44.
The next digit of our result is 0. 
Result so far: 10250.0
The remainder is 44 after subtracting 0 from 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 7:
If we divide 440 by 72, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 10250.6
If we subtract 432 from 440, 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.

Advancing to step 8:
When dividing 80 by 72, we get 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 10250.61
If we subtract 72 from 80, 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.

Step 9:
The number 72 fits into 80 1 times, leaving a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 10250.611
If we take 72 away from 80, 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.

The final result is 10250.611 with a remainder of 0.0008.
