980337 divided by 78 
The aim is to understand the frequency of 78 in 980337.

Advancing to step 1:
When dividing 9 by 78, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 78

Step 2:
If we divide 98 by 78, we get 1 and a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 78 from 98, we get 20.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 78

Going ahead to step 3:
78 can be fit into 200 2 times, resulting in a remainder of 44.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 156 from 200 leaves us with 44.
Take the next digit (3) from the dividend and append it to 44, then repeat: 443 / 78

Going ahead to step 4:
The number 78 fits into 443 5 times, leaving a remainder of 53.
Put 5 as the next digit of the answer. 
Result so far: 125.0
The remainder is 53 after subtracting 390 from 443.
Include the next digit (3) from the dividend after 53, then repeat: 533 / 78

Moving on to step 5:
The number 78 fits into 533 6 times, leaving a remainder of 65.
Use 6 as the next digit of our solution. 
Result so far: 1256.0
The remainder is 65 after subtracting 468 from 533.
Append the next digit (7) from the dividend to 65 and continue with: 657 / 78

Going ahead to step 6:
78 goes into 657 8 times with a remainder of 33.
The next digit of our result is 8. 
Result so far: 12568.0
If we subtract 624 from 657, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 7:
78 goes into 330 4 times with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 12568.4
The remainder is 18 after subtracting 312 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
78 can be fit into 180 2 times, resulting in a remainder of 24.
The next digit of our result is 2. 
Result so far: 12568.42
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
If we divide 240 by 78, we get 3 and a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 12568.423
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.

Advancing to step 10:
78 can be fit into 60 0 times, resulting in a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 12568.423
If we subtract 0 from 60, we 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.

Step 11:
78 can be fit into 600 7 times, resulting in a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 12568.42307
If we subtract 546 from 600, we 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.

On to step 12:
When dividing 540 by 78, we get 6 with a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 12568.423076
Subtracting 468 from 540 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 13:
If we divide 720 by 78, we get 9 and a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 12568.4230769
The remainder is 18 after subtracting 702 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 14:
180 divided by 78 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 12568.42307692
Subtract 156 from 180 to 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.

Our division results in 12568.42307692 with a remaining 2.4e-08.
