We're dividing 711904 by 80 
The aim is to understand the frequency of 80 in 711904.

Step 1:
When dividing 7 by 80, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 80

Going ahead to step 2:
80 goes into 71 0 times with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Include the next digit (1) from the dividend after 71, then repeat: 711 / 80

Moving on to step 3:
When dividing 711 by 80, we get 8 with a remainder of 71.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 640 from 711 to get 71.
Bring next digit (9) of the dividend behind the 71 and repeat the process: 719 / 80

Advancing to step 4:
719 divided by 80 is 8 with a remainder of 79.
Write down 8 as next digit of the result. 
Result so far: 88.0
If we subtract 640 from 719, we get 79.
Bring next digit (0) of the dividend behind the 79 and repeat the process: 790 / 80

On to step 5:
The number 80 fits into 790 9 times, leaving a remainder of 70.
Use 9 as the next digit of our solution. 
Result so far: 889.0
Deduct 720 from 790 and we're left with 70.
Append the next digit (4) from the dividend to 70 and continue with: 704 / 80

Step 6:
704 divided by 80 is 8 with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 8898.0
If we take 640 away from 704, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 7:
80 goes into 640 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 8898.8
Subtract 640 from 640 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 8:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 8898.8
If we take 0 away from 0, we end up 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.

Step 9:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8898.8
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.

In conclusion, the division gives 8898.8 with a balance of 0.0.
