We're dividing 777759 by 72 
The aim is to understand the frequency of 72 in 777759.

Advancing to step 1:
When dividing 7 by 72, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 72

Advancing to step 2:
The number 72 fits into 77 1 times, leaving a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 72 away from 77, we end up with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 72

Moving on to step 3:
72 goes into 57 0 times with a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 57, we end up with 57.
Take the next digit (7) from the dividend and append it to 57, then repeat: 577 / 72

Step 4:
When dividing 577 by 72, we get 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 108.0
Subtract 576 from 577 to get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 72

Going ahead to step 5:
72 can be fit into 15 0 times, resulting in a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 1080.0
If we subtract 0 from 15, we get 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 72

Let's proceed to step 6:
159 divided by 72 is 2 with a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 10802.0
If we take 144 away from 159, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
150 divided by 72 is 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 10802.2
The remainder is 6 after subtracting 144 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
72 can be fit into 60 0 times, resulting in a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 10802.2
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
When dividing 600 by 72, we get 8 with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 10802.208
Deduct 576 from 600 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
240 divided by 72 is 3 with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 10802.2083
The remainder is 24 after subtracting 216 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
When dividing 240 by 72, we get 3 with a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 10802.20833
Subtracting 216 from 240 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 10802.20833 with a remaining 2.4e-05.
