395804 ÷ 80 
The aim is to understand the frequency of 80 in 395804.

Step 1:
80 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 80

On to step 2:
The number 80 fits into 39 0 times, leaving a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Fetch the next digit (5) from the dividend, attach it to 39 and continue: 395 / 80

Moving on to step 3:
The number 80 fits into 395 4 times, leaving a remainder of 75.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 320 from 395 to get 75.
Take the next digit (8) from the dividend and append it to 75, then repeat: 758 / 80

Advancing to step 4:
If we divide 758 by 80, we get 9 and a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
If we take 720 away from 758, we end up with 38.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 80

Moving on to step 5:
The number 80 fits into 380 4 times, leaving a remainder of 60.
Write down 4 as next digit of the result. 
Result so far: 494.0
Subtracting 320 from 380 leaves us with 60.
Bring next digit (4) of the dividend behind the 60 and repeat the process: 604 / 80

Moving on to step 6:
604 divided by 80 is 7 with a remainder of 44.
The number 7 becomes the next digit in our result. 
Result so far: 4947.0
Deduct 560 from 604 and we're left 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.

Step 7:
When dividing 440 by 80, we get 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 4947.5
Deduct 400 from 440 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
400 divided by 80 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 4947.55
Deduct 400 from 400 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.

In conclusion, the division gives 4947.55 with a balance of 0.0.
