Let's divide 489526 by 78
The aim is to understand the frequency of 78 in 489526.

Step 1:
If we divide 4 by 78, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 78

Moving on to step 2:
48 divided by 78 is 0 with a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 78

Step 3:
78 can be fit into 489 6 times, resulting in a remainder of 21.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 468 from 489 and we're left with 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 78

Moving on to step 4:
78 can be fit into 215 2 times, resulting in a remainder of 59.
Use 2 as the next digit of our solution. 
Result so far: 62.0
Subtracting 156 from 215 leaves us with 59.
Take the next digit (2) from the dividend and append it to 59, then repeat: 592 / 78

On to step 5:
The number 78 fits into 592 7 times, leaving a remainder of 46.
The next digit of our result is 7. 
Result so far: 627.0
Subtract 546 from 592 to get 46.
Bring next digit (6) of the dividend behind the 46 and repeat the process: 466 / 78

On to step 6:
78 can be fit into 466 5 times, resulting in a remainder of 76.
Write down 5 as next digit of the result. 
Result so far: 6275.0
Subtracting 390 from 466 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.

Advancing to step 7:
When dividing 760 by 78, we get 9 with a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 6275.9
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.

Let's proceed to step 8:
78 can be fit into 580 7 times, resulting in a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 6275.97
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 9:
When dividing 340 by 78, we get 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 6275.974
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 10:
If we divide 280 by 78, we get 3 and a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 6275.9743
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.

Advancing to step 11:
The number 78 fits into 460 5 times, leaving a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 6275.97435
The remainder is 70 after subtracting 390 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 12:
700 divided by 78 is 8 with a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 6275.974358
The remainder is 76 after subtracting 624 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 13:
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: 6275.9743589
If we subtract 702 from 760, we 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.

Let's proceed to step 14:
78 can be fit into 580 7 times, resulting in a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 6275.97435897
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.

The final outcome is 6275.97435897, with a leftover of 3.4e-08.
