Let's divide 502880 by 78
The aim is to understand the frequency of 78 in 502880.

Moving on to step 1:
78 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 78

Moving on to step 2:
78 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Fetch the next digit (2) from the dividend, attach it to 50 and continue: 502 / 78

Advancing to step 3:
If we divide 502 by 78, we get 6 and a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 468 away from 502, we end up with 34.
Take the next digit (8) from the dividend and append it to 34, then repeat: 348 / 78

Let's proceed to step 4:
When dividing 348 by 78, we get 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
Subtracting 312 from 348 leaves us with 36.
Bring next digit (8) of the dividend behind the 36 and repeat the process: 368 / 78

Step 5:
The number 78 fits into 368 4 times, leaving a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 644.0
Subtracting 312 from 368 leaves us with 56.
Fetch the next digit (0) from the dividend, attach it to 56 and continue: 560 / 78

Moving on to step 6:
If we divide 560 by 78, we get 7 and a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 6447.0
Subtracting 546 from 560 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
140 divided by 78 is 1 with a remainder of 62.
The next digit of our result is 1. 
Result so far: 6447.1
Subtract 78 from 140 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 8:
When dividing 620 by 78, we get 7 with a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 6447.17
Deduct 546 from 620 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 9:
78 can be fit into 740 9 times, resulting in a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 6447.179
Subtracting 702 from 740 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 10:
When dividing 380 by 78, we get 4 with a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 6447.1794
Subtracting 312 from 380 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 11:
680 divided by 78 is 8 with a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 6447.17948
Subtracting 624 from 680 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 12:
The number 78 fits into 560 7 times, leaving a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 6447.179487
Subtracting 546 from 560 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 13:
When dividing 140 by 78, we get 1 with a remainder of 62.
The next digit of our result is 1. 
Result so far: 6447.1794871
Subtracting 78 from 140 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 14:
The number 78 fits into 620 7 times, leaving a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 6447.17948717
Subtracting 546 from 620 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

In conclusion, the division gives 6447.17948717 with a balance of 7.4e-08.
