75328 divided by 78 
The aim is to understand the frequency of 78 in 75328.

Step 1:
The number 78 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 78

Moving on to step 2:
The number 78 fits into 75 0 times, leaving a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Grab the next digit (3) from the dividend, add it to 75, then carry on: 753 / 78

Moving on to step 3:
78 goes into 753 9 times with a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 702 from 753 leaves us with 51.
Include the next digit (2) from the dividend after 51, then repeat: 512 / 78

Step 4:
512 divided by 78 is 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 96.0
If we subtract 468 from 512, we get 44.
Fetch the next digit (8) from the dividend, attach it to 44 and continue: 448 / 78

Going ahead to step 5:
448 divided by 78 is 5 with a remainder of 58.
The number 5 becomes the next digit in our result. 
Result so far: 965.0
Subtract 390 from 448 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 6:
The number 78 fits into 580 7 times, leaving a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 965.7
Deduct 546 from 580 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 7:
78 goes into 340 4 times with a remainder of 28.
The next digit of our result is 4. 
Result so far: 965.74
If we subtract 312 from 340, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 8:
If we divide 280 by 78, we get 3 and a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 965.743
Deduct 234 from 280 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 9:
78 can be fit into 460 5 times, resulting in a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 965.7435
If we take 390 away from 460, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 10:
78 can be fit into 700 8 times, resulting in a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 965.74358
Subtracting 624 from 700 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 11:
When dividing 760 by 78, we get 9 with a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 965.743589
Deduct 702 from 760 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 12:
If we divide 580 by 78, we get 7 and a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 965.7435897
If we subtract 546 from 580, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 13:
78 goes into 340 4 times with a remainder of 28.
The next digit of our result is 4. 
Result so far: 965.74358974
The remainder is 28 after subtracting 312 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 965.74358974 with a remainder of 2.8e-08.
