We divide 521264 by 72
The aim is to understand the frequency of 72 in 521264.

Step 1:
72 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 72

Let's proceed to step 2:
52 divided by 72 is 0 with a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Bring next digit (1) of the dividend behind the 52 and repeat the process: 521 / 72

Moving on to step 3:
72 goes into 521 7 times with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 504 from 521 and we're left with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 72

Moving on to step 4:
When dividing 172 by 72, we get 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 72.0
The remainder is 28 after subtracting 144 from 172.
Grab the next digit (6) from the dividend, add it to 28, then carry on: 286 / 72

Let's proceed to step 5:
If we divide 286 by 72, we get 3 and a remainder of 70.
The number 3 becomes the next digit in our result. 
Result so far: 723.0
Subtracting 216 from 286 leaves us with 70.
Append the next digit (4) from the dividend to 70 and continue with: 704 / 72

On to step 6:
When dividing 704 by 72, we get 9 with a remainder of 56.
Record the quotient 9 as the next digit in the result. 
Result so far: 7239.0
Subtracting 648 from 704 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 7:
When dividing 560 by 72, we get 7 with a remainder of 56.
Record the quotient 7 as the next digit in the result. 
Result so far: 7239.7
If we subtract 504 from 560, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 8:
560 divided by 72 is 7 with a remainder of 56.
Record the quotient 7 as the next digit in the result. 
Result so far: 7239.77
Deduct 504 from 560 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

In conclusion, the division gives 7239.77 with a balance of 0.056.
