Let's divide 670653 by 78
The aim is to understand the frequency of 78 in 670653.

On to step 1:
The number 78 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 78

On to step 2:
78 goes into 67 0 times with a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 67 leaves us with 67.
Include the next digit (0) from the dividend after 67, then repeat: 670 / 78

Going ahead to step 3:
670 divided by 78 is 8 with a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 624 away from 670, we end up with 46.
Include the next digit (6) from the dividend after 46, then repeat: 466 / 78

Step 4:
78 can be fit into 466 5 times, resulting in a remainder of 76.
Use 5 as the next digit of our solution. 
Result so far: 85.0
Deduct 390 from 466 and we're left with 76.
Take the next digit (5) from the dividend and append it to 76, then repeat: 765 / 78

Going ahead to step 5:
78 goes into 765 9 times with a remainder of 63.
The number 9 becomes the next digit in our result. 
Result so far: 859.0
If we subtract 702 from 765, we get 63.
Bring next digit (3) of the dividend behind the 63 and repeat the process: 633 / 78

Let's proceed to step 6:
When dividing 633 by 78, we get 8 with a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 8598.0
Subtracting 624 from 633 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
The number 78 fits into 90 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 8598.1
If we subtract 78 from 90, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
When dividing 120 by 78, we get 1 with a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 8598.11
The remainder is 42 after subtracting 78 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The quotient of the division is 8598.11, and the remainder is 0.042.
