Let's divide 276579 by 78
The aim is to understand the frequency of 78 in 276579.

Going ahead to step 1:
The number 78 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 78

Advancing to step 2:
78 can be fit into 27 0 times, resulting in a remainder of 27.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 27 after subtracting 0 from 27.
Fetch the next digit (6) from the dividend, attach it to 27 and continue: 276 / 78

Going ahead to step 3:
276 divided by 78 is 3 with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 234 from 276 leaves us with 42.
Bring next digit (5) of the dividend behind the 42 and repeat the process: 425 / 78

Step 4:
425 divided by 78 is 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 35.0
Deduct 390 from 425 and we're left with 35.
Include the next digit (7) from the dividend after 35, then repeat: 357 / 78

Let's proceed to step 5:
78 can be fit into 357 4 times, resulting in a remainder of 45.
Put 4 as the next digit of the answer. 
Result so far: 354.0
Deduct 312 from 357 and we're left with 45.
Fetch the next digit (9) from the dividend, attach it to 45 and continue: 459 / 78

Advancing to step 6:
If we divide 459 by 78, we get 5 and a remainder of 69.
The number 5 becomes the next digit in our result. 
Result so far: 3545.0
If we subtract 390 from 459, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 7:
78 can be fit into 690 8 times, resulting in a remainder of 66.
Record the quotient 8 as the next digit in the result. 
Result so far: 3545.8
Subtracting 624 from 690 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 8:
The number 78 fits into 660 8 times, leaving a remainder of 36.
The next digit of our result is 8. 
Result so far: 3545.88
Deduct 624 from 660 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 3545.88 with a remaining 0.036.
