Let's divide 446438 by 78
The aim is to understand the frequency of 78 in 446438.

Step 1:
78 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 78

Advancing to step 2:
44 divided by 78 is 0 with a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Grab the next digit (6) from the dividend, add it to 44, then carry on: 446 / 78

On to step 3:
When dividing 446 by 78, we get 5 with a remainder of 56.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 390 from 446 to get 56.
Include the next digit (4) from the dividend after 56, then repeat: 564 / 78

Going ahead to step 4:
78 goes into 564 7 times with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 57.0
The remainder is 18 after subtracting 546 from 564.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 78

Step 5:
The number 78 fits into 183 2 times, leaving a remainder of 27.
Record the quotient 2 as the next digit in the result. 
Result so far: 572.0
If we take 156 away from 183, we end up with 27.
Bring next digit (8) of the dividend behind the 27 and repeat the process: 278 / 78

On to step 6:
278 divided by 78 is 3 with a remainder of 44.
Put 3 as the next digit of the answer. 
Result so far: 5723.0
Subtract 234 from 278 to get 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 7:
The number 78 fits into 440 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 5723.5
Subtracting 390 from 440 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
500 divided by 78 is 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 5723.56
If we subtract 468 from 500, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
When dividing 320 by 78, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 5723.564
Subtracting 312 from 320 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
80 divided by 78 is 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 5723.5641
If we subtract 78 from 80, we get 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 11:
78 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 5723.5641
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.

Let's proceed to step 12:
78 can be fit into 200 2 times, resulting in a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 5723.564102
If we subtract 156 from 200, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 13:
If we divide 440 by 78, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 5723.5641025
If we take 390 away from 440, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 14:
500 divided by 78 is 6 with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 5723.56410256
Subtract 468 from 500 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 5723.56410256 with a balance of 3.2e-08.
