15204616 ÷ 78 
The aim is to understand the frequency of 78 in 15204616.

Let's proceed to step 1:
78 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 78

Going ahead to step 2:
If we divide 15 by 78, we get 0 and a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 78

Advancing to step 3:
152 divided by 78 is 1 with a remainder of 74.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 78 from 152 leaves us with 74.
Grab the next digit (0) from the dividend, add it to 74, then carry on: 740 / 78

On to step 4:
If we divide 740 by 78, we get 9 and a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we take 702 away from 740, we end up with 38.
Grab the next digit (4) from the dividend, add it to 38, then carry on: 384 / 78

On to step 5:
The number 78 fits into 384 4 times, leaving a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 194.0
The remainder is 72 after subtracting 312 from 384.
Append the next digit (6) from the dividend to 72 and continue with: 726 / 78

Let's proceed to step 6:
When dividing 726 by 78, we get 9 with a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 1949.0
The remainder is 24 after subtracting 702 from 726.
Append the next digit (1) from the dividend to 24 and continue with: 241 / 78

Step 7:
241 divided by 78 is 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 19493.0
Subtract 234 from 241 to get 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 78

Going ahead to step 8:
78 can be fit into 76 0 times, resulting in a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 194930.0
Subtracting 0 from 76 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.

Moving on to step 9:
The number 78 fits into 760 9 times, leaving a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 194930.9
If we take 702 away from 760, we end up 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.

Advancing to step 10:
580 divided by 78 is 7 with a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 194930.97
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.

Advancing 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: 194930.974
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.

On to step 12:
280 divided by 78 is 3 with a remainder of 46.
The next digit of our result is 3. 
Result so far: 194930.9743
Subtract 234 from 280 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 13:
78 can be fit into 460 5 times, resulting in a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 194930.97435
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.

Advancing to step 14:
The number 78 fits into 700 8 times, leaving a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 194930.974358
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.

Moving on to step 15:
The number 78 fits into 760 9 times, leaving a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 194930.9743589
If we take 702 away from 760, we end up 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 16:
580 divided by 78 is 7 with a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 194930.97435897
Deduct 546 from 580 and we're left 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.

In conclusion, the division gives 194930.97435897 with a balance of 3.4e-08.
