We look at the division of 603033 by 78 
The aim is to understand the frequency of 78 in 603033.

On to step 1:
78 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 78

Step 2:
The number 78 fits into 60 0 times, leaving a remainder of 60.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 60 after subtracting 0 from 60.
Bring next digit (3) of the dividend behind the 60 and repeat the process: 603 / 78

On to step 3:
78 can be fit into 603 7 times, resulting in a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 546 from 603, we get 57.
Take the next digit (0) from the dividend and append it to 57, then repeat: 570 / 78

Step 4:
78 can be fit into 570 7 times, resulting in a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
The remainder is 24 after subtracting 546 from 570.
Append the next digit (3) from the dividend to 24 and continue with: 243 / 78

Going ahead to step 5:
243 divided by 78 is 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 773.0
Deduct 234 from 243 and we're left with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 78

Going ahead to step 6:
If we divide 93 by 78, we get 1 and a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 7731.0
Deduct 78 from 93 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
If we divide 150 by 78, we get 1 and a remainder of 72.
Use 1 as the next digit of our solution. 
Result so far: 7731.1
If we take 78 away from 150, we end up 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 8:
If we divide 720 by 78, we get 9 and a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 7731.19
Deduct 702 from 720 and we're left 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.

Going ahead to step 9:
If we divide 180 by 78, we get 2 and a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 7731.192
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.

Let's proceed to step 10:
78 goes into 240 3 times with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 7731.1923
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 11:
78 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 7731.1923
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.

Moving on to step 12:
600 divided by 78 is 7 with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 7731.192307
The remainder is 54 after subtracting 546 from 600.
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 13:
The number 78 fits into 540 6 times, leaving a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 7731.1923076
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.

Moving on to step 14:
If we divide 720 by 78, we get 9 and a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 7731.19230769
Deduct 702 from 720 and we're left 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.

In conclusion, the division gives 7731.19230769 with a balance of 1.8e-08.
