Let's divide 438776 by 80
The aim is to understand the frequency of 80 in 438776.

Going ahead to step 1:
If we divide 4 by 80, we get 0 and 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.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 80

Moving on to step 2:
If we divide 43 by 80, we get 0 and a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Include the next digit (8) from the dividend after 43, then repeat: 438 / 80

Let's proceed to step 3:
80 goes into 438 5 times with a remainder of 38.
The next digit of our result is 5. 
Result so far: 5.0
If we take 400 away from 438, we end up with 38.
Bring next digit (7) of the dividend behind the 38 and repeat the process: 387 / 80

Going ahead to step 4:
387 divided by 80 is 4 with a remainder of 67.
The next digit of our result is 4. 
Result so far: 54.0
Subtracting 320 from 387 leaves us with 67.
Append the next digit (7) from the dividend to 67 and continue with: 677 / 80

On to step 5:
When dividing 677 by 80, we get 8 with a remainder of 37.
The number 8 becomes the next digit in our result. 
Result so far: 548.0
If we subtract 640 from 677, we get 37.
Include the next digit (6) from the dividend after 37, then repeat: 376 / 80

Going ahead to step 6:
376 divided by 80 is 4 with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 5484.0
Deduct 320 from 376 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 7:
80 goes into 560 7 times with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 5484.7
Deduct 560 from 560 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
80 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5484.7
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
When dividing 0 by 80, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5484.7
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 5484.7 and a remainder of 0.0.
