We look at the division of 34260246 by 78 
The aim is to understand the frequency of 78 in 34260246.

Let's proceed to step 1:
3 divided by 78 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 78

Moving on to step 2:
The number 78 fits into 34 0 times, leaving a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Bring next digit (2) of the dividend behind the 34 and repeat the process: 342 / 78

On to step 3:
The number 78 fits into 342 4 times, leaving a remainder of 30.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 312 from 342 leaves us with 30.
Fetch the next digit (6) from the dividend, attach it to 30 and continue: 306 / 78

Let's proceed to step 4:
306 divided by 78 is 3 with a remainder of 72.
The next digit of our result is 3. 
Result so far: 43.0
The remainder is 72 after subtracting 234 from 306.
Take the next digit (0) from the dividend and append it to 72, then repeat: 720 / 78

Advancing to step 5:
78 can be fit into 720 9 times, resulting in a remainder of 18.
The next digit of our result is 9. 
Result so far: 439.0
Deduct 702 from 720 and we're left with 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 78

Going ahead to step 6:
If we divide 182 by 78, we get 2 and a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 4392.0
If we subtract 156 from 182, we get 26.
Fetch the next digit (4) from the dividend, attach it to 26 and continue: 264 / 78

On to step 7:
78 goes into 264 3 times with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 43923.0
Subtract 234 from 264 to get 30.
Bring next digit (6) of the dividend behind the 30 and repeat the process: 306 / 78

Advancing to step 8:
When dividing 306 by 78, we get 3 with a remainder of 72.
The next digit of our result is 3. 
Result so far: 439233.0
If we take 234 away from 306, we end up 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.

On to step 9:
720 divided by 78 is 9 with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 439233.9
If we take 702 away from 720, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 10:
78 goes into 180 2 times with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 439233.92
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.

Going ahead to step 11:
78 can be fit into 240 3 times, resulting in a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 439233.923
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.

Step 12:
If we divide 60 by 78, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 439233.923
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 13:
If we divide 600 by 78, we get 7 and a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 439233.92307
If we take 546 away from 600, we end up 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.

Step 14:
78 can be fit into 540 6 times, resulting in a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 439233.923076
If we take 468 away from 540, we end up 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 15:
The number 78 fits into 720 9 times, leaving a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 439233.9230769
Subtract 702 from 720 to 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 16:
78 can be fit into 180 2 times, resulting in a remainder of 24.
The next digit of our result is 2. 
Result so far: 439233.92307692
Subtracting 156 from 180 leaves us 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.

The final result is 439233.92307692 with a remainder of 2.4e-08.
