We're dividing 423349 by 78 
The aim is to understand the frequency of 78 in 423349.

Advancing to step 1:
78 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 78

Step 2:
78 goes into 42 0 times with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 78

Going ahead to step 3:
78 can be fit into 423 5 times, resulting in a remainder of 33.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 33 after subtracting 390 from 423.
Append the next digit (3) from the dividend to 33 and continue with: 333 / 78

Let's proceed to step 4:
78 goes into 333 4 times with a remainder of 21.
Write down 4 as next digit of the result. 
Result so far: 54.0
If we take 312 away from 333, we end up with 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 78

Advancing to step 5:
The number 78 fits into 214 2 times, leaving a remainder of 58.
The next digit of our result is 2. 
Result so far: 542.0
If we subtract 156 from 214, we get 58.
Fetch the next digit (9) from the dividend, attach it to 58 and continue: 589 / 78

Step 6:
589 divided by 78 is 7 with a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 5427.0
If we take 546 away from 589, we end up 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.

Going ahead to step 7:
If we divide 430 by 78, we get 5 and a remainder of 40.
The next digit of our result is 5. 
Result so far: 5427.5
If we take 390 away from 430, we end up 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.

Step 8:
78 can be fit into 400 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 5427.55
Subtract 390 from 400 to get 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 5427.55 with a balance of 0.01.
