We look at the division of 701703 by 78 
The aim is to understand the frequency of 78 in 701703.

Advancing to step 1:
When dividing 7 by 78, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 78

Going ahead to step 2:
78 goes into 70 0 times with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Fetch the next digit (1) from the dividend, attach it to 70 and continue: 701 / 78

On to step 3:
78 goes into 701 8 times with a remainder of 77.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 624 from 701 to get 77.
Grab the next digit (7) from the dividend, add it to 77, then carry on: 777 / 78

Let's proceed to step 4:
The number 78 fits into 777 9 times, leaving a remainder of 75.
Write down 9 as next digit of the result. 
Result so far: 89.0
Subtracting 702 from 777 leaves us with 75.
Fetch the next digit (0) from the dividend, attach it to 75 and continue: 750 / 78

Advancing to step 5:
The number 78 fits into 750 9 times, leaving a remainder of 48.
The next digit of our result is 9. 
Result so far: 899.0
If we take 702 away from 750, we end up with 48.
Fetch the next digit (3) from the dividend, attach it to 48 and continue: 483 / 78

On to step 6:
When dividing 483 by 78, we get 6 with a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 8996.0
If we subtract 468 from 483, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
78 can be fit into 150 1 times, resulting in a remainder of 72.
Put 1 as the next digit of the answer. 
Result so far: 8996.1
Subtract 78 from 150 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 8:
78 goes into 720 9 times with a remainder of 18.
The next digit of our result is 9. 
Result so far: 8996.19
If we subtract 702 from 720, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
The number 78 fits into 180 2 times, leaving a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 8996.192
If we subtract 156 from 180, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
78 goes into 240 3 times with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 8996.1923
Subtracting 234 from 240 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 11:
60 divided by 78 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 8996.1923
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
600 divided by 78 is 7 with a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 8996.192307
Subtract 546 from 600 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 13:
If we divide 540 by 78, we get 6 and a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 8996.1923076
Subtract 468 from 540 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 14:
78 can be fit into 720 9 times, resulting in a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 8996.19230769
If we take 702 away from 720, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 8996.19230769 with a remaining 1.8e-08.
