Let's divide 548424 by 78
The aim is to understand the frequency of 78 in 548424.

Going ahead to step 1:
78 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 78

On to step 2:
If we divide 54 by 78, we get 0 and a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Append the next digit (8) from the dividend to 54 and continue with: 548 / 78

Going ahead to step 3:
When dividing 548 by 78, we get 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 546 from 548 leaves us with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 78

Moving on to step 4:
24 divided by 78 is 0 with a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
Subtracting 0 from 24 leaves us with 24.
Include the next digit (2) from the dividend after 24, then repeat: 242 / 78

Going ahead to step 5:
If we divide 242 by 78, we get 3 and a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 703.0
Subtract 234 from 242 to get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 78

Let's proceed to step 6:
If we divide 84 by 78, we get 1 and a remainder of 6.
The next digit of our result is 1. 
Result so far: 7031.0
The remainder is 6 after subtracting 78 from 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
60 divided by 78 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 7031.0
Deduct 0 from 60 and we're left 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.

Advancing to step 8:
600 divided by 78 is 7 with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 7031.07
Subtracting 546 from 600 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 9:
When dividing 540 by 78, we get 6 with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 7031.076
Deduct 468 from 540 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 10:
The number 78 fits into 720 9 times, leaving a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 7031.0769
Subtract 702 from 720 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 11:
78 can be fit into 180 2 times, resulting in a remainder of 24.
The next digit of our result is 2. 
Result so far: 7031.07692
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
The number 78 fits into 240 3 times, leaving a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 7031.076923
Deduct 234 from 240 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
78 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 7031.076923
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 14:
If we divide 600 by 78, we get 7 and a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 7031.07692307
If we subtract 546 from 600, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

In conclusion, the division gives 7031.07692307 with a balance of 5.4e-08.
