We're dividing 723469 by 78 
The aim is to understand the frequency of 78 in 723469.

Step 1:
78 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 78

Moving on to step 2:
The number 78 fits into 72 0 times, leaving a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Bring next digit (3) of the dividend behind the 72 and repeat the process: 723 / 78

Advancing to step 3:
78 goes into 723 9 times with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 21 after subtracting 702 from 723.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 78

Moving on to step 4:
78 can be fit into 214 2 times, resulting in a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
Deduct 156 from 214 and we're left with 58.
Include the next digit (6) from the dividend after 58, then repeat: 586 / 78

Step 5:
If we divide 586 by 78, we get 7 and a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 927.0
Deduct 546 from 586 and we're left with 40.
Include the next digit (9) from the dividend after 40, then repeat: 409 / 78

Step 6:
78 goes into 409 5 times with a remainder of 19.
Record the quotient 5 as the next digit in the result. 
Result so far: 9275.0
If we subtract 390 from 409, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
190 divided by 78 is 2 with a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 9275.2
Deduct 156 from 190 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.

On to step 8:
If we divide 340 by 78, we get 4 and a remainder of 28.
The next digit of our result is 4. 
Result so far: 9275.24
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.

Let's proceed to step 9:
78 goes into 280 3 times with a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 9275.243
If we subtract 234 from 280, we 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.

On to step 10:
When dividing 460 by 78, we get 5 with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 9275.2435
If we take 390 away from 460, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 11:
78 can be fit into 700 8 times, resulting in a remainder of 76.
The next digit of our result is 8. 
Result so far: 9275.24358
Subtracting 624 from 700 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.

Let's proceed to step 12:
The number 78 fits into 760 9 times, leaving a remainder of 58.
The next digit of our result is 9. 
Result so far: 9275.243589
Deduct 702 from 760 and we're left 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.

Moving on to step 13:
The number 78 fits into 580 7 times, leaving a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 9275.2435897
Subtracting 546 from 580 leaves us 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.

On to step 14:
The number 78 fits into 340 4 times, leaving a remainder of 28.
The next digit of our result is 4. 
Result so far: 9275.24358974
Subtracting 312 from 340 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

In conclusion, the division gives 9275.24358974 with a balance of 2.8e-08.
