We look at the division of 11459385 by 78 
The aim is to understand the frequency of 78 in 11459385.

Step 1:
1 divided by 78 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 78

Let's proceed to step 2:
78 can be fit into 11 0 times, resulting in a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 78

Advancing to step 3:
The number 78 fits into 114 1 times, leaving a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 36 after subtracting 78 from 114.
Fetch the next digit (5) from the dividend, attach it to 36 and continue: 365 / 78

Moving on to step 4:
78 goes into 365 4 times with a remainder of 53.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 312 from 365, we get 53.
Grab the next digit (9) from the dividend, add it to 53, then carry on: 539 / 78

Let's proceed to step 5:
If we divide 539 by 78, we get 6 and a remainder of 71.
The next digit of our result is 6. 
Result so far: 146.0
If we subtract 468 from 539, we get 71.
Fetch the next digit (3) from the dividend, attach it to 71 and continue: 713 / 78

Moving on to step 6:
713 divided by 78 is 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 1469.0
The remainder is 11 after subtracting 702 from 713.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 78

On to step 7:
When dividing 118 by 78, we get 1 with a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 14691.0
If we subtract 78 from 118, we get 40.
Include the next digit (5) from the dividend after 40, then repeat: 405 / 78

Going ahead to step 8:
405 divided by 78 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 146915.0
Subtracting 390 from 405 leaves us 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 9:
The number 78 fits into 150 1 times, leaving a remainder of 72.
The next digit of our result is 1. 
Result so far: 146915.1
Subtracting 78 from 150 leaves us 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:
If we divide 720 by 78, we get 9 and a remainder of 18.
The next digit of our result is 9. 
Result so far: 146915.19
If we take 702 away from 720, we end up 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.

Moving on to step 11:
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: 146915.192
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.

Advancing to step 12:
78 goes into 240 3 times with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 146915.1923
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 13:
78 can be fit into 60 0 times, resulting in a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 146915.1923
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.

Moving on to step 14:
When dividing 600 by 78, we get 7 with a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 146915.192307
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.

Step 15:
The number 78 fits into 540 6 times, leaving a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 146915.1923076
Subtracting 468 from 540 leaves us 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 16:
78 goes into 720 9 times with a remainder of 18.
The next digit of our result is 9. 
Result so far: 146915.19230769
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.

The final outcome is 146915.19230769, with a leftover of 1.8e-08.
