We look at the division of 275281 by 78 
The aim is to understand the frequency of 78 in 275281.

Let's proceed to step 1:
78 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 78

Advancing to step 2:
The number 78 fits into 27 0 times, leaving a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 27 to get 27.
Take the next digit (5) from the dividend and append it to 27, then repeat: 275 / 78

Let's proceed to step 3:
The number 78 fits into 275 3 times, leaving a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 234 from 275, we get 41.
Fetch the next digit (2) from the dividend, attach it to 41 and continue: 412 / 78

On to step 4:
78 goes into 412 5 times with a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Deduct 390 from 412 and we're left with 22.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 78

Advancing to step 5:
78 can be fit into 228 2 times, resulting in a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 352.0
Subtracting 156 from 228 leaves us with 72.
Append the next digit (1) from the dividend to 72 and continue with: 721 / 78

Moving on to step 6:
The number 78 fits into 721 9 times, leaving a remainder of 19.
The next digit of our result is 9. 
Result so far: 3529.0
The remainder is 19 after subtracting 702 from 721.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
The number 78 fits into 190 2 times, leaving a remainder of 34.
The next digit of our result is 2. 
Result so far: 3529.2
The remainder is 34 after subtracting 156 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 8:
When dividing 340 by 78, we get 4 with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 3529.24
Deduct 312 from 340 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
When dividing 280 by 78, we get 3 with a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 3529.243
Subtract 234 from 280 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 10:
If we divide 460 by 78, we get 5 and a remainder of 70.
The next digit of our result is 5. 
Result so far: 3529.2435
If we subtract 390 from 460, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 11:
When dividing 700 by 78, we get 8 with a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 3529.24358
Subtract 624 from 700 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 12:
The number 78 fits into 760 9 times, leaving a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 3529.243589
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.

Let's proceed to step 13:
78 goes into 580 7 times with a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 3529.2435897
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 14:
78 goes into 340 4 times with a remainder of 28.
The next digit of our result is 4. 
Result so far: 3529.24358974
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.

In conclusion, the division gives 3529.24358974 with a balance of 2.8e-08.
