We divide 26371 by 78
The aim is to understand the frequency of 78 in 26371.

On to step 1:
2 divided by 78 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 78

Advancing to step 2:
When dividing 26 by 78, we get 0 with a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 26, we end up with 26.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 78

Moving on to step 3:
263 divided by 78 is 3 with a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 234 from 263 leaves us with 29.
Grab the next digit (7) from the dividend, add it to 29, then carry on: 297 / 78

On to step 4:
78 can be fit into 297 3 times, resulting in a remainder of 63.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
If we take 234 away from 297, we end up with 63.
Take the next digit (1) from the dividend and append it to 63, then repeat: 631 / 78

Going ahead to step 5:
78 can be fit into 631 8 times, resulting in a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 338.0
Deduct 624 from 631 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 6:
When dividing 70 by 78, we get 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 338.0
If we subtract 0 from 70, 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.

Let's proceed to step 7:
78 can be fit into 700 8 times, resulting in a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 338.08
Deduct 624 from 700 and we're left 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.

Going ahead to step 8:
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: 338.089
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 9:
78 goes into 580 7 times with a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 338.0897
The remainder is 34 after subtracting 546 from 580.
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 10:
If we divide 340 by 78, we get 4 and a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 338.08974
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.

Advancing to step 11:
If we divide 280 by 78, we get 3 and a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 338.089743
The remainder is 46 after subtracting 234 from 280.
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 12:
The number 78 fits into 460 5 times, leaving a remainder of 70.
The next digit of our result is 5. 
Result so far: 338.0897435
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.

Advancing to step 13:
700 divided by 78 is 8 with a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 338.08974358
If we subtract 624 from 700, we 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.

The quotient of the division is 338.08974358, and the remainder is 7.6e-08.
