We look at the division of 272901 by 78 
The aim is to understand the frequency of 78 in 272901.

Advancing to step 1:
78 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 78

On to step 2:
If we divide 27 by 78, we get 0 and a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 27 after subtracting 0 from 27.
Grab the next digit (2) from the dividend, add it to 27, then carry on: 272 / 78

Let's proceed to step 3:
If we divide 272 by 78, we get 3 and a remainder of 38.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 234 from 272 to get 38.
Fetch the next digit (9) from the dividend, attach it to 38 and continue: 389 / 78

On to step 4:
78 goes into 389 4 times with a remainder of 77.
The next digit of our result is 4. 
Result so far: 34.0
The remainder is 77 after subtracting 312 from 389.
Fetch the next digit (0) from the dividend, attach it to 77 and continue: 770 / 78

On to step 5:
770 divided by 78 is 9 with a remainder of 68.
The next digit of our result is 9. 
Result so far: 349.0
If we subtract 702 from 770, we get 68.
Include the next digit (1) from the dividend after 68, then repeat: 681 / 78

Advancing to step 6:
681 divided by 78 is 8 with a remainder of 57.
Put 8 as the next digit of the answer. 
Result so far: 3498.0
If we subtract 624 from 681, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 7:
570 divided by 78 is 7 with a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 3498.7
Deduct 546 from 570 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 8:
The number 78 fits into 240 3 times, leaving a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 3498.73
Deduct 234 from 240 and we're left 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.

Going ahead to step 9:
60 divided by 78 is 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 3498.73
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
78 can be fit into 600 7 times, resulting in a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 3498.7307
Deduct 546 from 600 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 11:
78 goes into 540 6 times with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 3498.73076
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.

Advancing to step 12:
When dividing 720 by 78, we get 9 with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 3498.730769
If we subtract 702 from 720, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 13:
78 can be fit into 180 2 times, resulting in a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 3498.7307692
The remainder is 24 after subtracting 156 from 180.
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 14:
The number 78 fits into 240 3 times, leaving a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 3498.73076923
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.

In conclusion, the division gives 3498.73076923 with a balance of 6e-09.
