We're dividing 447702 by 78 
The aim is to understand the frequency of 78 in 447702.

Step 1:
The number 78 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 78

Advancing to step 2:
If we divide 44 by 78, we get 0 and a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Fetch the next digit (7) from the dividend, attach it to 44 and continue: 447 / 78

On to step 3:
447 divided by 78 is 5 with a remainder of 57.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 390 from 447, we get 57.
Take the next digit (7) from the dividend and append it to 57, then repeat: 577 / 78

Step 4:
If we divide 577 by 78, we get 7 and a remainder of 31.
The next digit of our result is 7. 
Result so far: 57.0
Subtracting 546 from 577 leaves us with 31.
Fetch the next digit (0) from the dividend, attach it to 31 and continue: 310 / 78

Step 5:
When dividing 310 by 78, we get 3 with a remainder of 76.
The number 3 becomes the next digit in our result. 
Result so far: 573.0
If we take 234 away from 310, we end up with 76.
Grab the next digit (2) from the dividend, add it to 76, then carry on: 762 / 78

Let's proceed to step 6:
78 goes into 762 9 times with a remainder of 60.
The next digit of our result is 9. 
Result so far: 5739.0
The remainder is 60 after subtracting 702 from 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 7:
When dividing 600 by 78, we get 7 with a remainder of 54.
The next digit of our result is 7. 
Result so far: 5739.7
Subtracting 546 from 600 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 8:
78 can be fit into 540 6 times, resulting in a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 5739.76
If we subtract 468 from 540, we get 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 9:
When dividing 720 by 78, we get 9 with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 5739.769
The remainder is 18 after subtracting 702 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
180 divided by 78 is 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 5739.7692
If we subtract 156 from 180, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 11:
240 divided by 78 is 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 5739.76923
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.

Moving on to step 12:
The number 78 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 5739.76923
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.

Let's proceed to step 13:
If we divide 600 by 78, we get 7 and a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 5739.7692307
If we subtract 546 from 600, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 14:
The number 78 fits into 540 6 times, leaving a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 5739.76923076
If we take 468 away from 540, we end up 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.

The final outcome is 5739.76923076, with a leftover of 7.2e-08.
