We divide 515464 by 72
The aim is to understand the frequency of 72 in 515464.

On to step 1:
If we divide 5 by 72, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 72

Going ahead to step 2:
If we divide 51 by 72, we get 0 and a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Append the next digit (5) from the dividend to 51 and continue with: 515 / 72

Advancing to step 3:
The number 72 fits into 515 7 times, leaving a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 11 after subtracting 504 from 515.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 72

Moving on to step 4:
72 can be fit into 114 1 times, resulting in a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 71.0
Deduct 72 from 114 and we're left with 42.
Take the next digit (6) from the dividend and append it to 42, then repeat: 426 / 72

Let's proceed to step 5:
72 goes into 426 5 times with a remainder of 66.
The number 5 becomes the next digit in our result. 
Result so far: 715.0
If we subtract 360 from 426, we get 66.
Grab the next digit (4) from the dividend, add it to 66, then carry on: 664 / 72

Advancing to step 6:
72 goes into 664 9 times with a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 7159.0
The remainder is 16 after subtracting 648 from 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
160 divided by 72 is 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 7159.2
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
72 goes into 160 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 7159.22
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 7159.22 and a remainder of 0.016.
