892407 divided by 78 
The aim is to understand the frequency of 78 in 892407.

Going ahead to step 1:
78 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 78

Let's proceed to step 2:
78 goes into 89 1 times with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 78 from 89, we get 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 78

Moving on to step 3:
112 divided by 78 is 1 with a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 78 away from 112, we end up with 34.
Fetch the next digit (4) from the dividend, attach it to 34 and continue: 344 / 78

Moving on to step 4:
78 goes into 344 4 times with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 114.0
If we take 312 away from 344, we end up with 32.
Take the next digit (0) from the dividend and append it to 32, then repeat: 320 / 78

Going ahead to step 5:
78 goes into 320 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 1144.0
Subtract 312 from 320 to get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 78

Advancing to step 6:
When dividing 87 by 78, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 11441.0
The remainder is 9 after subtracting 78 from 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
When dividing 90 by 78, we get 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 11441.1
Subtracting 78 from 90 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
120 divided by 78 is 1 with a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 11441.11
Subtracting 78 from 120 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 11441.11 with a remainder of 0.042.
