We divide 29620 by 78
The aim is to understand the frequency of 78 in 29620.

Let's proceed to step 1:
If we divide 2 by 78, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 78

Step 2:
29 divided by 78 is 0 with a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 29 leaves us with 29.
Grab the next digit (6) from the dividend, add it to 29, then carry on: 296 / 78

On to step 3:
78 goes into 296 3 times with a remainder of 62.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 234 from 296 leaves us with 62.
Grab the next digit (2) from the dividend, add it to 62, then carry on: 622 / 78

Going ahead to step 4:
78 goes into 622 7 times with a remainder of 76.
Write down 7 as next digit of the result. 
Result so far: 37.0
Subtracting 546 from 622 leaves us with 76.
Take the next digit (0) from the dividend and append it to 76, then repeat: 760 / 78

Going ahead to step 5:
78 goes into 760 9 times with a remainder of 58.
The next digit of our result is 9. 
Result so far: 379.0
Subtract 702 from 760 to 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 6:
580 divided by 78 is 7 with a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 379.7
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.

Moving on to step 7:
When dividing 340 by 78, we get 4 with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 379.74
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.

Step 8:
When dividing 280 by 78, we get 3 with a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 379.743
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 9:
If we divide 460 by 78, we get 5 and a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 379.7435
Subtract 390 from 460 to 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 10:
78 goes into 700 8 times with a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 379.74358
Subtracting 624 from 700 leaves us 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 11:
When dividing 760 by 78, we get 9 with a remainder of 58.
The next digit of our result is 9. 
Result so far: 379.743589
The remainder is 58 after subtracting 702 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 12:
When dividing 580 by 78, we get 7 with a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 379.7435897
If we subtract 546 from 580, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 13:
If we divide 340 by 78, we get 4 and a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 379.74358974
If we subtract 312 from 340, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 379.74358974 and a remainder of 2.8e-08.
