We're dividing 923239 by 78 
The aim is to understand the frequency of 78 in 923239.

Going ahead to step 1:
9 divided by 78 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 78

Let's proceed to step 2:
92 divided by 78 is 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 78 from 92, we get 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 78

Advancing to step 3:
143 divided by 78 is 1 with a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 78 from 143, we get 65.
Include the next digit (2) from the dividend after 65, then repeat: 652 / 78

Let's proceed to step 4:
78 can be fit into 652 8 times, resulting in a remainder of 28.
The next digit of our result is 8. 
Result so far: 118.0
If we subtract 624 from 652, we get 28.
Include the next digit (3) from the dividend after 28, then repeat: 283 / 78

Let's proceed to step 5:
If we divide 283 by 78, we get 3 and a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 1183.0
The remainder is 49 after subtracting 234 from 283.
Append the next digit (9) from the dividend to 49 and continue with: 499 / 78

Going ahead to step 6:
499 divided by 78 is 6 with a remainder of 31.
The next digit of our result is 6. 
Result so far: 11836.0
Deduct 468 from 499 and we're left 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.

On to step 7:
78 goes into 310 3 times with a remainder of 76.
Record the quotient 3 as the next digit in the result. 
Result so far: 11836.3
Subtracting 234 from 310 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.

Going ahead to step 8:
If we divide 760 by 78, we get 9 and a remainder of 58.
The next digit of our result is 9. 
Result so far: 11836.39
The remainder is 58 after subtracting 702 from 760.
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 9:
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: 11836.397
Deduct 546 from 580 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 10:
340 divided by 78 is 4 with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 11836.3974
Deduct 312 from 340 and we're left 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 11:
When dividing 280 by 78, we get 3 with a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 11836.39743
If we take 234 away from 280, we end up 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.

On to step 12:
78 can be fit into 460 5 times, resulting in a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 11836.397435
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.

Going ahead to step 13:
700 divided by 78 is 8 with a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 11836.3974358
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.

Step 14:
78 can be fit into 760 9 times, resulting in a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 11836.39743589
Subtracting 702 from 760 leaves us 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.

After the division, we end up with 11836.39743589 and a remainder of 5.8e-08.
