26313 divided by 78 
The aim is to understand the frequency of 78 in 26313.

On to step 1:
When dividing 2 by 78, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 78

Step 2:
26 divided by 78 is 0 with a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 26 to get 26.
Bring next digit (3) of the dividend behind the 26 and repeat the process: 263 / 78

On to step 3:
78 goes into 263 3 times with a remainder of 29.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 234 from 263 and we're left with 29.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 78

Going ahead to step 4:
291 divided by 78 is 3 with a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
If we subtract 234 from 291, we get 57.
Bring next digit (3) of the dividend behind the 57 and repeat the process: 573 / 78

Advancing to step 5:
The number 78 fits into 573 7 times, leaving a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 337.0
Deduct 546 from 573 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 6:
78 can be fit into 270 3 times, resulting in a remainder of 36.
The next digit of our result is 3. 
Result so far: 337.3
Subtracting 234 from 270 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 7:
If we divide 360 by 78, we get 4 and a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 337.34
The remainder is 48 after subtracting 312 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 8:
If we divide 480 by 78, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 337.346
The remainder is 12 after subtracting 468 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
78 goes into 120 1 times with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 337.3461
Subtract 78 from 120 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 10:
420 divided by 78 is 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 337.34615
Deduct 390 from 420 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
When dividing 300 by 78, we get 3 with a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 337.346153
Subtracting 234 from 300 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 12:
When dividing 660 by 78, we get 8 with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 337.3461538
Subtract 624 from 660 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 13:
When dividing 360 by 78, we get 4 with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 337.34615384
Subtracting 312 from 360 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 337.34615384 with a remainder of 4.8e-08.
