Let's divide 420452 by 80
The aim is to understand the frequency of 80 in 420452.

Going ahead to step 1:
80 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 80

Step 2:
When dividing 42 by 80, we get 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 80

Let's proceed to step 3:
80 can be fit into 420 5 times, resulting in a remainder of 20.
The next digit of our result is 5. 
Result so far: 5.0
If we take 400 away from 420, we end up with 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 80

Advancing to step 4:
80 goes into 204 2 times with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 52.0
Subtracting 160 from 204 leaves us with 44.
Fetch the next digit (5) from the dividend, attach it to 44 and continue: 445 / 80

Let's proceed to step 5:
The number 80 fits into 445 5 times, leaving a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 525.0
If we subtract 400 from 445, we get 45.
Take the next digit (2) from the dividend and append it to 45, then repeat: 452 / 80

Advancing to step 6:
If we divide 452 by 80, we get 5 and a remainder of 52.
The next digit of our result is 5. 
Result so far: 5255.0
Subtract 400 from 452 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 7:
80 goes into 520 6 times with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 5255.6
Subtracting 480 from 520 leaves us 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.

Step 8:
80 goes into 400 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5255.65
If we take 400 away from 400, 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.

Moving on to step 9:
80 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 5255.65
If we subtract 0 from 0, we 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 10:
0 divided by 80 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5255.65
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 5255.65, with a leftover of 0.0.
