We look at the division of 992437 by 78 
The aim is to understand the frequency of 78 in 992437.

Going ahead to step 1:
9 divided by 78 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 78

Going ahead to step 2:
If we divide 99 by 78, we get 1 and a remainder of 21.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 78 from 99 to get 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 78

On to step 3:
If we divide 212 by 78, we get 2 and a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 56 after subtracting 156 from 212.
Include the next digit (4) from the dividend after 56, then repeat: 564 / 78

Let's proceed to step 4:
78 goes into 564 7 times with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 127.0
Deduct 546 from 564 and we're left with 18.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 78

Going ahead to step 5:
The number 78 fits into 183 2 times, leaving a remainder of 27.
The next digit of our result is 2. 
Result so far: 1272.0
If we subtract 156 from 183, we get 27.
Fetch the next digit (7) from the dividend, attach it to 27 and continue: 277 / 78

Step 6:
277 divided by 78 is 3 with a remainder of 43.
Write down 3 as next digit of the result. 
Result so far: 12723.0
Subtracting 234 from 277 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 7:
When dividing 430 by 78, we get 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 12723.5
Subtracting 390 from 430 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
If we divide 400 by 78, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 12723.55
Subtracting 390 from 400 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 12723.55 with a balance of 0.01.
