657876 ÷ 78 
The aim is to understand the frequency of 78 in 657876.

Let's proceed to step 1:
If we divide 6 by 78, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 78

Step 2:
The number 78 fits into 65 0 times, leaving a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Take the next digit (7) from the dividend and append it to 65, then repeat: 657 / 78

Advancing to step 3:
657 divided by 78 is 8 with a remainder of 33.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 624 from 657 and we're left with 33.
Bring next digit (8) of the dividend behind the 33 and repeat the process: 338 / 78

Advancing to step 4:
78 goes into 338 4 times with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 84.0
Subtracting 312 from 338 leaves us with 26.
Include the next digit (7) from the dividend after 26, then repeat: 267 / 78

Moving on to step 5:
When dividing 267 by 78, we get 3 with a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 843.0
Subtracting 234 from 267 leaves us with 33.
Fetch the next digit (6) from the dividend, attach it to 33 and continue: 336 / 78

Step 6:
When dividing 336 by 78, we get 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 8434.0
The remainder is 24 after subtracting 312 from 336.
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 7:
78 can be fit into 240 3 times, resulting in a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 8434.3
Subtract 234 from 240 to get 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 8:
78 can be fit into 60 0 times, resulting in a remainder of 60.
The next digit of our result is 0. 
Result so far: 8434.3
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
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: 8434.307
The remainder is 54 after subtracting 546 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 10:
If we divide 540 by 78, we get 6 and a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 8434.3076
Deduct 468 from 540 and we're left 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.

Advancing to step 11:
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: 8434.30769
Subtract 702 from 720 to 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.

Let's proceed to step 12:
If we divide 180 by 78, we get 2 and a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 8434.307692
Subtracting 156 from 180 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
The number 78 fits into 240 3 times, leaving a remainder of 6.
The next digit of our result is 3. 
Result so far: 8434.3076923
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 14:
The number 78 fits into 60 0 times, leaving a remainder of 60.
The next digit of our result is 0. 
Result so far: 8434.3076923
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.

Our division results in 8434.3076923 with a remaining 6e-08.
