Let's divide 763928 by 72
The aim is to understand the frequency of 72 in 763928.

Step 1:
The number 72 fits into 7 0 times, leaving 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.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 72

Going ahead to step 2:
When dividing 76 by 72, we get 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 72 from 76, we get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 72

On to step 3:
72 goes into 43 0 times with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 43 after subtracting 0 from 43.
Fetch the next digit (9) from the dividend, attach it to 43 and continue: 439 / 72

Moving on to step 4:
439 divided by 72 is 6 with a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 106.0
Subtract 432 from 439 to get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 72

On to step 5:
The number 72 fits into 72 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1061.0
Deduct 72 from 72 and we're left with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 72

Moving on to step 6:
72 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 10610.0
Subtracting 0 from 8 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
72 goes into 80 1 times with a remainder of 8.
The next digit of our result is 1. 
Result so far: 10610.1
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
If we divide 80 by 72, we get 1 and a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 10610.11
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 10610.11, with a leftover of 0.008.
