We look at the division of 916480 by 72 
The aim is to understand the frequency of 72 in 916480.

Moving on to step 1:
72 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 72

Going ahead to step 2:
If we divide 91 by 72, we get 1 and a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 72 from 91, we get 19.
Grab the next digit (6) from the dividend, add it to 19, then carry on: 196 / 72

Moving on to step 3:
When dividing 196 by 72, we get 2 with a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 144 from 196 and we're left with 52.
Fetch the next digit (4) from the dividend, attach it to 52 and continue: 524 / 72

Moving on to step 4:
If we divide 524 by 72, we get 7 and a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 127.0
If we take 504 away from 524, we end up with 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 72

On to step 5:
72 can be fit into 208 2 times, resulting in a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 1272.0
The remainder is 64 after subtracting 144 from 208.
Bring next digit (0) of the dividend behind the 64 and repeat the process: 640 / 72

Going ahead to step 6:
72 can be fit into 640 8 times, resulting in a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 12728.0
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.

On to step 7:
The number 72 fits into 640 8 times, leaving a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 12728.8
The remainder is 64 after subtracting 576 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 8:
72 goes into 640 8 times with a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 12728.88
Subtracting 576 from 640 leaves us 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.

In conclusion, the division gives 12728.88 with a balance of 0.064.
