We look at the division of 554240 by 78 
The aim is to understand the frequency of 78 in 554240.

Moving on to step 1:
78 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 78

On to step 2:
78 goes into 55 0 times with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Append the next digit (4) from the dividend to 55 and continue with: 554 / 78

On to step 3:
78 can be fit into 554 7 times, resulting in a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 546 away from 554, we end up with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 78

Let's proceed to step 4:
82 divided by 78 is 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 71.0
If we subtract 78 from 82, we get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 78

Going ahead to step 5:
78 goes into 44 0 times with a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 710.0
Subtracting 0 from 44 leaves us with 44.
Bring next digit (0) of the dividend behind the 44 and repeat the process: 440 / 78

On to step 6:
The number 78 fits into 440 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 7105.0
The remainder is 50 after subtracting 390 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 7:
78 goes into 500 6 times with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 7105.6
If we take 468 away from 500, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 8:
78 goes into 320 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 7105.64
If we subtract 312 from 320, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
80 divided by 78 is 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 7105.641
Deduct 78 from 80 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
78 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 7105.641
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
The number 78 fits into 200 2 times, leaving a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 7105.64102
Subtracting 156 from 200 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 12:
78 goes into 440 5 times with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 7105.641025
If we subtract 390 from 440, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
When dividing 500 by 78, we get 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 7105.6410256
If we take 468 away from 500, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 14:
78 goes into 320 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 7105.64102564
The remainder is 8 after subtracting 312 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 7105.64102564 with a remaining 8e-09.
