We're dividing 448090 by 78 
The aim is to understand the frequency of 78 in 448090.

Let's proceed to 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 take 0 away from 4, we end up with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 78

Step 2:
If we divide 44 by 78, we get 0 and a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 44, we end up with 44.
Grab the next digit (8) from the dividend, add it to 44, then carry on: 448 / 78

Going ahead to step 3:
The number 78 fits into 448 5 times, leaving a remainder of 58.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 390 away from 448, we end up with 58.
Include the next digit (0) from the dividend after 58, then repeat: 580 / 78

Moving on to step 4:
78 goes into 580 7 times with a remainder of 34.
The next digit of our result is 7. 
Result so far: 57.0
If we subtract 546 from 580, we get 34.
Fetch the next digit (9) from the dividend, attach it to 34 and continue: 349 / 78

Let's proceed to step 5:
78 goes into 349 4 times with a remainder of 37.
The number 4 becomes the next digit in our result. 
Result so far: 574.0
Subtracting 312 from 349 leaves us with 37.
Grab the next digit (0) from the dividend, add it to 37, then carry on: 370 / 78

Going ahead to step 6:
When dividing 370 by 78, we get 4 with a remainder of 58.
Record the quotient 4 as the next digit in the result. 
Result so far: 5744.0
Subtract 312 from 370 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 7:
78 goes into 580 7 times with a remainder of 34.
The next digit of our result is 7. 
Result so far: 5744.7
The remainder is 34 after subtracting 546 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
If we divide 340 by 78, we get 4 and a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 5744.74
Subtract 312 from 340 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 9:
78 goes into 280 3 times with a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 5744.743
If we take 234 away from 280, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 10:
When dividing 460 by 78, we get 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 5744.7435
If we subtract 390 from 460, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 11:
If we divide 700 by 78, we get 8 and a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 5744.74358
Subtracting 624 from 700 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 12:
78 can be fit into 760 9 times, resulting in a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 5744.743589
If we subtract 702 from 760, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 13:
78 can be fit into 580 7 times, resulting in a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 5744.7435897
If we subtract 546 from 580, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 14:
When dividing 340 by 78, we get 4 with a remainder of 28.
The next digit of our result is 4. 
Result so far: 5744.74358974
Subtract 312 from 340 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 5744.74358974 with a remainder of 2.8e-08.
