We're dividing 279994 by 78 
The aim is to understand the frequency of 78 in 279994.

Moving on to step 1:
When dividing 2 by 78, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 78

Step 2:
If we divide 27 by 78, we get 0 and a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 27, we get 27.
Include the next digit (9) from the dividend after 27, then repeat: 279 / 78

Advancing to step 3:
78 goes into 279 3 times with a remainder of 45.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 234 away from 279, we end up with 45.
Grab the next digit (9) from the dividend, add it to 45, then carry on: 459 / 78

Moving on to step 4:
When dividing 459 by 78, we get 5 with a remainder of 69.
Write down 5 as next digit of the result. 
Result so far: 35.0
Deduct 390 from 459 and we're left with 69.
Include the next digit (9) from the dividend after 69, then repeat: 699 / 78

Moving on to step 5:
The number 78 fits into 699 8 times, leaving a remainder of 75.
Record the quotient 8 as the next digit in the result. 
Result so far: 358.0
If we take 624 away from 699, we end up with 75.
Grab the next digit (4) from the dividend, add it to 75, then carry on: 754 / 78

Advancing to step 6:
754 divided by 78 is 9 with a remainder of 52.
Use 9 as the next digit of our solution. 
Result so far: 3589.0
The remainder is 52 after subtracting 702 from 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 7:
When dividing 520 by 78, we get 6 with a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 3589.6
The remainder is 52 after subtracting 468 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 8:
78 can be fit into 520 6 times, resulting in a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 3589.66
Deduct 468 from 520 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

In conclusion, the division gives 3589.66 with a balance of 0.052.
