We look at the division of 523244 by 78 
The aim is to understand the frequency of 78 in 523244.

Step 1:
If we divide 5 by 78, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 78

Let's proceed to step 2:
52 divided by 78 is 0 with a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Fetch the next digit (3) from the dividend, attach it to 52 and continue: 523 / 78

Going ahead to step 3:
The number 78 fits into 523 6 times, leaving a remainder of 55.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 468 from 523 and we're left with 55.
Grab the next digit (2) from the dividend, add it to 55, then carry on: 552 / 78

On to step 4:
When dividing 552 by 78, we get 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 67.0
Deduct 546 from 552 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 78

Going ahead to step 5:
78 can be fit into 64 0 times, resulting in a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 670.0
Subtracting 0 from 64 leaves us with 64.
Take the next digit (4) from the dividend and append it to 64, then repeat: 644 / 78

On to step 6:
The number 78 fits into 644 8 times, leaving a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 6708.0
Subtract 624 from 644 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
78 can be fit into 200 2 times, resulting in a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 6708.2
If we take 156 away from 200, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 8:
When dividing 440 by 78, we get 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 6708.25
If we subtract 390 from 440, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
When dividing 500 by 78, we get 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 6708.256
The remainder is 32 after subtracting 468 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 10:
The number 78 fits into 320 4 times, leaving a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 6708.2564
Subtract 312 from 320 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
If we divide 80 by 78, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 6708.25641
Subtract 78 from 80 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
20 divided by 78 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 6708.25641
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
When dividing 200 by 78, we get 2 with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 6708.2564102
Subtracting 156 from 200 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 14:
440 divided by 78 is 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 6708.25641025
The remainder is 50 after subtracting 390 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 6708.25641025 with a remaining 5e-08.
