We divide 664494 by 78
The aim is to understand the frequency of 78 in 664494.

Going ahead to step 1:
When dividing 6 by 78, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 78

On to step 2:
78 can be fit into 66 0 times, resulting in a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Include the next digit (4) from the dividend after 66, then repeat: 664 / 78

On to step 3:
78 can be fit into 664 8 times, resulting in a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 40 after subtracting 624 from 664.
Bring next digit (4) of the dividend behind the 40 and repeat the process: 404 / 78

Let's proceed to step 4:
404 divided by 78 is 5 with a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
If we take 390 away from 404, we end up with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 78

On to step 5:
78 can be fit into 149 1 times, resulting in a remainder of 71.
The number 1 becomes the next digit in our result. 
Result so far: 851.0
Deduct 78 from 149 and we're left with 71.
Fetch the next digit (4) from the dividend, attach it to 71 and continue: 714 / 78

Going ahead to step 6:
78 can be fit into 714 9 times, resulting in a remainder of 12.
The next digit of our result is 9. 
Result so far: 8519.0
Subtract 702 from 714 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
When dividing 120 by 78, we get 1 with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 8519.1
If we take 78 away from 120, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 8:
If we divide 420 by 78, we get 5 and a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 8519.15
Deduct 390 from 420 and we're left with 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 9:
When dividing 300 by 78, we get 3 with a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 8519.153
The remainder is 66 after subtracting 234 from 300.
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 10:
The number 78 fits into 660 8 times, leaving a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 8519.1538
Subtract 624 from 660 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 11:
When dividing 360 by 78, we get 4 with a remainder of 48.
The next digit of our result is 4. 
Result so far: 8519.15384
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.

Step 12:
If we divide 480 by 78, we get 6 and a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 8519.153846
Subtract 468 from 480 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
The number 78 fits into 120 1 times, leaving a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 8519.1538461
Subtracting 78 from 120 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 14:
If we divide 420 by 78, we get 5 and a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 8519.15384615
If we subtract 390 from 420, we 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.

In conclusion, the division gives 8519.15384615 with a balance of 3e-08.
