We're dividing 763913 by 72 
The aim is to understand the frequency of 72 in 763913.

Let's proceed to step 1:
72 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 72

Let's proceed to step 2:
If we divide 76 by 72, we get 1 and a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 72 from 76 to get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 72

Step 3:
72 goes into 43 0 times with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 43 leaves us with 43.
Take the next digit (9) from the dividend and append it to 43, then repeat: 439 / 72

Moving on to step 4:
72 goes into 439 6 times with a remainder of 7.
The next digit of our result is 6. 
Result so far: 106.0
If we subtract 432 from 439, we get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 72

Advancing to step 5:
The number 72 fits into 71 0 times, leaving a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 1060.0
The remainder is 71 after subtracting 0 from 71.
Bring next digit (3) of the dividend behind the 71 and repeat the process: 713 / 72

Moving on to step 6:
When dividing 713 by 72, we get 9 with a remainder of 65.
Put 9 as the next digit of the answer. 
Result so far: 10609.0
Subtracting 648 from 713 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 7:
650 divided by 72 is 9 with a remainder of 2.
The next digit of our result is 9. 
Result so far: 10609.9
Deduct 648 from 650 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
20 divided by 72 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 10609.9
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
200 divided by 72 is 2 with a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 10609.902
If we subtract 144 from 200, 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.

Going ahead to step 10:
72 goes into 560 7 times with a remainder of 56.
The number 7 becomes the next digit in our result. 
Result so far: 10609.9027
Subtracting 504 from 560 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.

Advancing to step 11:
When dividing 560 by 72, we get 7 with a remainder of 56.
Put 7 as the next digit of the answer. 
Result so far: 10609.90277
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.

Our division results in 10609.90277 with a remaining 5.6e-05.
