We look at the division of 436325 by 78 
The aim is to understand the frequency of 78 in 436325.

Going ahead to step 1:
The number 78 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 78

On to step 2:
78 goes into 43 0 times with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Include the next digit (6) from the dividend after 43, then repeat: 436 / 78

Going ahead to step 3:
When dividing 436 by 78, we get 5 with a remainder of 46.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 390 from 436 to get 46.
Bring next digit (3) of the dividend behind the 46 and repeat the process: 463 / 78

Step 4:
463 divided by 78 is 5 with a remainder of 73.
Record the quotient 5 as the next digit in the result. 
Result so far: 55.0
If we take 390 away from 463, we end up with 73.
Grab the next digit (2) from the dividend, add it to 73, then carry on: 732 / 78

On to step 5:
When dividing 732 by 78, we get 9 with a remainder of 30.
Use 9 as the next digit of our solution. 
Result so far: 559.0
If we subtract 702 from 732, we get 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 78

Moving on to step 6:
305 divided by 78 is 3 with a remainder of 71.
The next digit of our result is 3. 
Result so far: 5593.0
The remainder is 71 after subtracting 234 from 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 7:
When dividing 710 by 78, we get 9 with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 5593.9
If we subtract 702 from 710, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
If we divide 80 by 78, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 5593.91
If we take 78 away from 80, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
The number 78 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 5593.91
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
When dividing 200 by 78, we get 2 with a remainder of 44.
The next digit of our result is 2. 
Result so far: 5593.9102
The remainder is 44 after subtracting 156 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 11:
78 can be fit into 440 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 5593.91025
The remainder is 50 after subtracting 390 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 12:
78 goes into 500 6 times with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 5593.910256
Subtracting 468 from 500 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 13:
78 goes into 320 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 5593.9102564
If we take 312 away from 320, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
78 can be fit into 80 1 times, resulting in a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 5593.91025641
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 5593.91025641 with a remaining 2e-09.
