778796 ÷ 72 
The aim is to understand the frequency of 72 in 778796.

Advancing to step 1:
If we divide 7 by 72, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 72

Going ahead to step 2:
If we divide 77 by 72, we get 1 and a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 72 away from 77, we end up with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 72

On to step 3:
72 goes into 58 0 times with a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 58, we end up with 58.
Bring next digit (7) of the dividend behind the 58 and repeat the process: 587 / 72

Advancing to step 4:
When dividing 587 by 72, we get 8 with a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 108.0
If we subtract 576 from 587, we get 11.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 72

Let's proceed to step 5:
72 can be fit into 119 1 times, resulting in a remainder of 47.
Put 1 as the next digit of the answer. 
Result so far: 1081.0
Subtract 72 from 119 to get 47.
Grab the next digit (6) from the dividend, add it to 47, then carry on: 476 / 72

Advancing to step 6:
72 can be fit into 476 6 times, resulting in a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 10816.0
Subtracting 432 from 476 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 7:
When dividing 440 by 72, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 10816.6
The remainder is 8 after subtracting 432 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
80 divided by 72 is 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 10816.61
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
80 divided by 72 is 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 10816.611
Subtracting 72 from 80 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.

Our division results in 10816.611 with a remaining 0.0008.
