We're dividing 223020 by 78 
The aim is to understand the frequency of 78 in 223020.

Going ahead to step 1:
The number 78 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 78

Let's proceed to step 2:
The number 78 fits into 22 0 times, leaving a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 22 leaves us with 22.
Bring next digit (3) of the dividend behind the 22 and repeat the process: 223 / 78

On to step 3:
The number 78 fits into 223 2 times, leaving a remainder of 67.
The next digit of our result is 2. 
Result so far: 2.0
If we take 156 away from 223, we end up with 67.
Take the next digit (0) from the dividend and append it to 67, then repeat: 670 / 78

On to step 4:
When dividing 670 by 78, we get 8 with a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Deduct 624 from 670 and we're left with 46.
Include the next digit (2) from the dividend after 46, then repeat: 462 / 78

Moving on to step 5:
78 can be fit into 462 5 times, resulting in a remainder of 72.
Write down 5 as next digit of the result. 
Result so far: 285.0
Subtracting 390 from 462 leaves us with 72.
Include the next digit (0) from the dividend after 72, then repeat: 720 / 78

Moving on to step 6:
78 can be fit into 720 9 times, resulting in a remainder of 18.
The next digit of our result is 9. 
Result so far: 2859.0
Subtracting 702 from 720 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
78 can be fit into 180 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 2859.2
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.

Let's proceed to step 8:
The number 78 fits into 240 3 times, leaving a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 2859.23
If we take 234 away from 240, we end up 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.

On to step 9:
When dividing 60 by 78, we get 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 2859.23
If we subtract 0 from 60, we 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.

Step 10:
If we divide 600 by 78, we get 7 and a remainder of 54.
The next digit of our result is 7. 
Result so far: 2859.2307
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.

Going ahead to step 11:
78 can be fit into 540 6 times, resulting in a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 2859.23076
The remainder is 72 after subtracting 468 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 12:
78 can be fit into 720 9 times, resulting in a remainder of 18.
The next digit of our result is 9. 
Result so far: 2859.230769
Subtracting 702 from 720 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 13:
The number 78 fits into 180 2 times, leaving a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 2859.2307692
If we subtract 156 from 180, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 14:
240 divided by 78 is 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 2859.23076923
If we subtract 234 from 240, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 2859.23076923 with a balance of 6e-09.
