We look at the division of 465688 by 72 
The aim is to understand the frequency of 72 in 465688.

Step 1:
If we divide 4 by 72, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 72

Going ahead to step 2:
If we divide 46 by 72, we get 0 and a remainder of 46.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 46 and we're left with 46.
Grab the next digit (5) from the dividend, add it to 46, then carry on: 465 / 72

Let's proceed to step 3:
72 goes into 465 6 times with a remainder of 33.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 432 from 465 to get 33.
Fetch the next digit (6) from the dividend, attach it to 33 and continue: 336 / 72

Let's proceed to step 4:
If we divide 336 by 72, we get 4 and a remainder of 48.
The next digit of our result is 4. 
Result so far: 64.0
The remainder is 48 after subtracting 288 from 336.
Grab the next digit (8) from the dividend, add it to 48, then carry on: 488 / 72

On to step 5:
72 goes into 488 6 times with a remainder of 56.
The next digit of our result is 6. 
Result so far: 646.0
Subtract 432 from 488 to get 56.
Include the next digit (8) from the dividend after 56, then repeat: 568 / 72

On to step 6:
If we divide 568 by 72, we get 7 and a remainder of 64.
The next digit of our result is 7. 
Result so far: 6467.0
If we take 504 away from 568, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 7:
72 goes into 640 8 times with a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 6467.8
Subtract 576 from 640 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 8:
When dividing 640 by 72, we get 8 with a remainder of 64.
The next digit of our result is 8. 
Result so far: 6467.88
If we take 576 away from 640, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 6467.88 with a remainder of 0.064.
