Let's divide 756223 by 72
The aim is to understand the frequency of 72 in 756223.

Step 1:
The number 72 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 72

Let's proceed to step 2:
The number 72 fits into 75 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 3 after subtracting 72 from 75.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 72

Step 3:
72 goes into 36 0 times with a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 36, we get 36.
Take the next digit (2) from the dividend and append it to 36, then repeat: 362 / 72

On to step 4:
72 goes into 362 5 times with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
Subtract 360 from 362 to get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 72

Moving on to step 5:
72 goes into 22 0 times with a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 1050.0
If we take 0 away from 22, we end up with 22.
Take the next digit (3) from the dividend and append it to 22, then repeat: 223 / 72

Advancing to step 6:
72 can be fit into 223 3 times, resulting in a remainder of 7.
The next digit of our result is 3. 
Result so far: 10503.0
If we subtract 216 from 223, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
70 divided by 72 is 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 10503.0
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 8:
72 goes into 700 9 times with a remainder of 52.
Write down 9 as next digit of the result. 
Result so far: 10503.09
If we take 648 away from 700, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 9:
72 can be fit into 520 7 times, resulting in a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 10503.097
Subtract 504 from 520 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.

Step 10:
The number 72 fits into 160 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 10503.0972
If we take 144 away from 160, we end up with 16.
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 11:
160 divided by 72 is 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 10503.09722
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 10503.09722 with a remaining 1.6e-05.
