We look at the division of 507776 by 72 
The aim is to understand the frequency of 72 in 507776.

Moving on to step 1:
72 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 72

Let's proceed to step 2:
If we divide 50 by 72, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Fetch the next digit (7) from the dividend, attach it to 50 and continue: 507 / 72

Moving on to step 3:
When dividing 507 by 72, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 504 from 507, we get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 72

On to step 4:
The number 72 fits into 37 0 times, leaving a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 70.0
The remainder is 37 after subtracting 0 from 37.
Grab the next digit (7) from the dividend, add it to 37, then carry on: 377 / 72

Step 5:
The number 72 fits into 377 5 times, leaving a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 705.0
Subtracting 360 from 377 leaves us with 17.
Bring next digit (6) of the dividend behind the 17 and repeat the process: 176 / 72

Advancing to step 6:
When dividing 176 by 72, we get 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 7052.0
If we take 144 away from 176, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 7:
When dividing 320 by 72, we get 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 7052.4
Subtracting 288 from 320 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 8:
72 goes into 320 4 times with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 7052.44
The remainder is 32 after subtracting 288 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 7052.44 with a remaining 0.032.
