We divide 992637 by 78
The aim is to understand the frequency of 78 in 992637.

Advancing to step 1:
9 divided by 78 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 78

Moving on to step 2:
If we divide 99 by 78, we get 1 and a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 78 from 99 leaves us with 21.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 78

Going ahead to step 3:
212 divided by 78 is 2 with a remainder of 56.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 56 after subtracting 156 from 212.
Include the next digit (6) from the dividend after 56, then repeat: 566 / 78

Let's proceed to step 4:
78 can be fit into 566 7 times, resulting in a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 127.0
Subtract 546 from 566 to get 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 78

Going ahead to step 5:
203 divided by 78 is 2 with a remainder of 47.
Use 2 as the next digit of our solution. 
Result so far: 1272.0
Subtracting 156 from 203 leaves us with 47.
Bring next digit (7) of the dividend behind the 47 and repeat the process: 477 / 78

Moving on to step 6:
477 divided by 78 is 6 with a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 12726.0
If we subtract 468 from 477, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
78 goes into 90 1 times with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 12726.1
If we subtract 78 from 90, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
If we divide 120 by 78, we get 1 and a remainder of 42.
The next digit of our result is 1. 
Result so far: 12726.11
The remainder is 42 after subtracting 78 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 12726.11 and a remainder of 0.042.
