We're dividing 530769 by 78 
The aim is to understand the frequency of 78 in 530769.

Step 1:
5 divided by 78 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 78

Let's proceed to step 2:
The number 78 fits into 53 0 times, leaving a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Take the next digit (0) from the dividend and append it to 53, then repeat: 530 / 78

Let's proceed to step 3:
530 divided by 78 is 6 with a remainder of 62.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 468 from 530 leaves us with 62.
Grab the next digit (7) from the dividend, add it to 62, then carry on: 627 / 78

Step 4:
If we divide 627 by 78, we get 8 and a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 68.0
If we subtract 624 from 627, we get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 78

Going ahead to step 5:
If we divide 36 by 78, we get 0 and a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 680.0
Subtract 0 from 36 to get 36.
Include the next digit (9) from the dividend after 36, then repeat: 369 / 78

Step 6:
369 divided by 78 is 4 with a remainder of 57.
The next digit of our result is 4. 
Result so far: 6804.0
The remainder is 57 after subtracting 312 from 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 7:
570 divided by 78 is 7 with a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 6804.7
If we take 546 away from 570, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 8:
78 can be fit into 240 3 times, resulting in a remainder of 6.
The next digit of our result is 3. 
Result so far: 6804.73
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.

Moving on to step 9:
If we divide 60 by 78, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 6804.73
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.

Going ahead to step 10:
600 divided by 78 is 7 with a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 6804.7307
If we take 546 away from 600, we end up 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.

Let's proceed to step 11:
78 goes into 540 6 times with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 6804.73076
If we subtract 468 from 540, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 12:
The number 78 fits into 720 9 times, leaving a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 6804.730769
The remainder is 18 after subtracting 702 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
If we divide 180 by 78, we get 2 and a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 6804.7307692
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.

Step 14:
240 divided by 78 is 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 6804.73076923
Subtracting 234 from 240 leaves us 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.

The final result is 6804.73076923 with a remainder of 6e-09.
