We look at the division of 72602 by 72 
The aim is to understand the frequency of 72 in 72602.

Going ahead to step 1:
If we divide 7 by 72, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 72

Advancing to step 2:
When dividing 72 by 72, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 72 from 72 leaves us with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 72

Let's proceed to step 3:
72 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 6, we end up with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 72

Let's proceed to step 4:
60 divided by 72 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 100.0
Subtract 0 from 60 to get 60.
Fetch the next digit (2) from the dividend, attach it to 60 and continue: 602 / 72

Step 5:
If we divide 602 by 72, we get 8 and a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 1008.0
If we subtract 576 from 602, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 6:
The number 72 fits into 260 3 times, leaving a remainder of 44.
Record the quotient 3 as the next digit in the result. 
Result so far: 1008.3
The remainder is 44 after subtracting 216 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 7:
440 divided by 72 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 1008.36
If we take 432 away from 440, 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.

Let's proceed to step 8:
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: 1008.361
Deduct 72 from 80 and we're left 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.

Moving on to step 9:
72 can be fit into 80 1 times, resulting in a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1008.3611
Deduct 72 from 80 and we're left 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 quotient of the division is 1008.3611, and the remainder is 8e-05.
