We're dividing 552582 by 78 
The aim is to understand the frequency of 78 in 552582.

Advancing to step 1:
When dividing 5 by 78, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 78

Going ahead to step 2:
78 goes into 55 0 times with a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Include the next digit (2) from the dividend after 55, then repeat: 552 / 78

Step 3:
78 goes into 552 7 times with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 546 from 552 leaves us with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 78

Step 4:
65 divided by 78 is 0 with a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
Deduct 0 from 65 and we're left with 65.
Take the next digit (8) from the dividend and append it to 65, then repeat: 658 / 78

Let's proceed to step 5:
78 can be fit into 658 8 times, resulting in a remainder of 34.
The next digit of our result is 8. 
Result so far: 708.0
Deduct 624 from 658 and we're left with 34.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 78

Advancing to step 6:
The number 78 fits into 342 4 times, leaving a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 7084.0
Subtract 312 from 342 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
300 divided by 78 is 3 with a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 7084.3
Subtract 234 from 300 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 8:
When dividing 660 by 78, we get 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 7084.38
Deduct 624 from 660 and we're left 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.

Advancing to step 9:
78 goes into 360 4 times with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 7084.384
Subtract 312 from 360 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 10:
78 can be fit into 480 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 7084.3846
Deduct 468 from 480 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
The number 78 fits into 120 1 times, leaving a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 7084.38461
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.

Moving on to step 12:
When dividing 420 by 78, we get 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 7084.384615
Subtract 390 from 420 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
78 goes into 300 3 times with a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 7084.3846153
If we subtract 234 from 300, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 14:
The number 78 fits into 660 8 times, leaving a remainder of 36.
The next digit of our result is 8. 
Result so far: 7084.38461538
The remainder is 36 after subtracting 624 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

In conclusion, the division gives 7084.38461538 with a balance of 3.6e-08.
