We look at the division of 12823 by 78 
The aim is to understand the frequency of 78 in 12823.

Moving on to step 1:
The number 78 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 78

Advancing to step 2:
If we divide 12 by 78, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 78

On to step 3:
When dividing 128 by 78, we get 1 with a remainder of 50.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 78 from 128 and we're left with 50.
Bring next digit (2) of the dividend behind the 50 and repeat the process: 502 / 78

On to step 4:
502 divided by 78 is 6 with a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we take 468 away from 502, we end up with 34.
Include the next digit (3) from the dividend after 34, then repeat: 343 / 78

Going ahead to step 5:
The number 78 fits into 343 4 times, leaving a remainder of 31.
Write down 4 as next digit of the result. 
Result so far: 164.0
Subtracting 312 from 343 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 6:
The number 78 fits into 310 3 times, leaving a remainder of 76.
Use 3 as the next digit of our solution. 
Result so far: 164.3
Deduct 234 from 310 and we're left 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.

Going ahead to step 7:
The number 78 fits into 760 9 times, leaving a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 164.39
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.

Going ahead to step 8:
78 can be fit into 580 7 times, resulting in a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 164.397
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.

Advancing to step 9:
78 goes into 340 4 times with a remainder of 28.
The next digit of our result is 4. 
Result so far: 164.3974
If we take 312 away from 340, we end up 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.

Let's proceed to step 10:
The number 78 fits into 280 3 times, leaving a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 164.39743
Subtracting 234 from 280 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 11:
The number 78 fits into 460 5 times, leaving a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 164.397435
Deduct 390 from 460 and we're left 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.

Moving on to step 12:
700 divided by 78 is 8 with a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 164.3974358
If we take 624 away from 700, we end up 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 13:
If we divide 760 by 78, we get 9 and a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 164.39743589
If we take 702 away from 760, we end up 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.

The final result is 164.39743589 with a remainder of 5.8e-08.
