We divide 428823 by 80
The aim is to understand the frequency of 80 in 428823.

Advancing to step 1:
4 divided by 80 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 80

On to step 2:
42 divided by 80 is 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Grab the next digit (8) from the dividend, add it to 42, then carry on: 428 / 80

Moving on to step 3:
428 divided by 80 is 5 with a remainder of 28.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 400 from 428 leaves us with 28.
Append the next digit (8) from the dividend to 28 and continue with: 288 / 80

Going ahead to step 4:
If we divide 288 by 80, we get 3 and a remainder of 48.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
The remainder is 48 after subtracting 240 from 288.
Append the next digit (2) from the dividend to 48 and continue with: 482 / 80

Going ahead to step 5:
When dividing 482 by 80, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 536.0
Subtract 480 from 482 to get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 80

Advancing to step 6:
The number 80 fits into 23 0 times, leaving a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 5360.0
If we subtract 0 from 23, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
When dividing 230 by 80, we get 2 with a remainder of 70.
Use 2 as the next digit of our solution. 
Result so far: 5360.2
Subtract 160 from 230 to 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 8:
700 divided by 80 is 8 with a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 5360.28
If we subtract 640 from 700, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
If we divide 600 by 80, we get 7 and a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 5360.287
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
If we divide 400 by 80, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5360.2875
Subtracting 400 from 400 leaves us 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 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5360.2875
Subtracting 0 from 0 leaves us 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 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5360.2875
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.

The final outcome is 5360.2875, with a leftover of 0.0.
