Let's divide 930020 by 72
The aim is to understand the frequency of 72 in 930020.

Let's proceed to step 1:
9 divided by 72 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 72

Going ahead to step 2:
When dividing 93 by 72, we get 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 21 after subtracting 72 from 93.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 72

Advancing to step 3:
When dividing 210 by 72, we get 2 with a remainder of 66.
The next digit of our result is 2. 
Result so far: 12.0
If we take 144 away from 210, we end up with 66.
Fetch the next digit (0) from the dividend, attach it to 66 and continue: 660 / 72

Going ahead to step 4:
If we divide 660 by 72, we get 9 and a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 129.0
Subtract 648 from 660 to get 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 72

Moving on to step 5:
When dividing 122 by 72, we get 1 with a remainder of 50.
Record the quotient 1 as the next digit in the result. 
Result so far: 1291.0
If we subtract 72 from 122, we get 50.
Bring next digit (0) of the dividend behind the 50 and repeat the process: 500 / 72

Advancing to step 6:
The number 72 fits into 500 6 times, leaving a remainder of 68.
Put 6 as the next digit of the answer. 
Result so far: 12916.0
The remainder is 68 after subtracting 432 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 7:
72 can be fit into 680 9 times, resulting in a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 12916.9
Subtracting 648 from 680 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:
If we divide 320 by 72, we get 4 and a remainder of 32.
The next digit of our result is 4. 
Result so far: 12916.94
Subtract 288 from 320 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
72 can be fit into 320 4 times, resulting in a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 12916.944
Deduct 288 from 320 and we're left 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.

Our division results in 12916.944 with a remaining 0.0032.
