The aim is to understand the frequency of 78 in 27080389.

Going ahead to step 1:
The number 78 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 78

Step 2:
When dividing 27 by 78, we get 0 with a remainder of 27.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 27, we get 27.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 78

Going ahead to step 3:
When dividing 270 by 78, we get 3 with a remainder of 36.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 234 from 270 leaves us with 36.
Take the next digit (8) from the dividend and append it to 36, then repeat: 368 / 78

On to step 4:
78 goes into 368 4 times with a remainder of 56.
The next digit of our result is 4. 
Result so far: 34.0
Deduct 312 from 368 and we're left with 56.
Take the next digit (0) from the dividend and append it to 56, then repeat: 560 / 78

Advancing to step 5:
78 can be fit into 560 7 times, resulting in a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 347.0
Subtract 546 from 560 to get 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 78

Advancing to step 6:
78 can be fit into 143 1 times, resulting in a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 3471.0
Deduct 78 from 143 and we're left with 65.
Fetch the next digit (8) from the dividend, attach it to 65 and continue: 658 / 78

On to step 7:
If we divide 658 by 78, we get 8 and a remainder of 34.
The next digit of our result is 8. 
Result so far: 34718.0
If we subtract 624 from 658, we get 34.
Include the next digit (9) from the dividend after 34, then repeat: 349 / 78

Advancing to step 8:
78 can be fit into 349 4 times, resulting in a remainder of 37.
Use 4 as the next digit of our solution. 
Result so far: 347184.0
Subtracting 312 from 349 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 9:
The number 78 fits into 370 4 times, leaving a remainder of 58.
Record the quotient 4 as the next digit in the result. 
Result so far: 347184.4
Subtracting 312 from 370 leaves us 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.

Going ahead to step 10:
78 can be fit into 580 7 times, resulting in a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 347184.47
Subtracting 546 from 580 leaves us 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.

On to step 11:
340 divided by 78 is 4 with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 347184.474
Subtracting 312 from 340 leaves us 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 12:
280 divided by 78 is 3 with a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 347184.4743
Subtracting 234 from 280 leaves us 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.

Moving on to step 13:
If we divide 460 by 78, we get 5 and a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 347184.47435
The remainder is 70 after subtracting 390 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 14:
78 can be fit into 700 8 times, resulting in a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 347184.474358
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.

Advancing to step 15:
78 can be fit into 760 9 times, resulting in a remainder of 58.
The next digit of our result is 9. 
Result so far: 347184.4743589
If we subtract 702 from 760, we 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.

On to step 16:
78 goes into 580 7 times with a remainder of 34.
The next digit of our result is 7. 
Result so far: 347184.47435897
Subtracting 546 from 580 leaves us 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.

The final result is 347184.47435897 with a remainder of 3.4e-08.
