Let's divide 828207 by 78
The aim is to understand the frequency of 78 in 828207.

On to step 1:
78 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 78

On to step 2:
82 divided by 78 is 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 4 after subtracting 78 from 82.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 78

On to step 3:
78 goes into 48 0 times with a remainder of 48.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 48 leaves us with 48.
Bring next digit (2) of the dividend behind the 48 and repeat the process: 482 / 78

Moving on to step 4:
78 can be fit into 482 6 times, resulting in a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 106.0
The remainder is 14 after subtracting 468 from 482.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 78

Moving on to step 5:
78 can be fit into 140 1 times, resulting in a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 1061.0
If we take 78 away from 140, we end up with 62.
Append the next digit (7) from the dividend to 62 and continue with: 627 / 78

Moving on to step 6:
When dividing 627 by 78, we get 8 with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 10618.0
If we subtract 624 from 627, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
The number 78 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 10618.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
The number 78 fits into 300 3 times, leaving a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 10618.03
If we take 234 away from 300, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 9:
The number 78 fits into 660 8 times, leaving a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 10618.038
The remainder is 36 after subtracting 624 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 10:
The number 78 fits into 360 4 times, leaving a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 10618.0384
Subtracting 312 from 360 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 11:
78 can be fit into 480 6 times, resulting in a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 10618.03846
If we take 468 away from 480, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
78 goes into 120 1 times with a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 10618.038461
If we take 78 away from 120, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 13:
78 can be fit into 420 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 10618.0384615
If we subtract 390 from 420, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
78 goes into 300 3 times with a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 10618.03846153
Subtracting 234 from 300 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Our division results in 10618.03846153 with a remaining 6.6e-08.
