We're dividing 430518 by 80 
The aim is to understand the frequency of 80 in 430518.

Moving on 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
Subtract 0 from 4 to get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 80

Moving on to step 2:
When dividing 43 by 80, we get 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Append the next digit (0) from the dividend to 43 and continue with: 430 / 80

Moving on to step 3:
80 can be fit into 430 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 400 from 430 and we're left with 30.
Append the next digit (5) from the dividend to 30 and continue with: 305 / 80

Advancing to step 4:
When dividing 305 by 80, we get 3 with a remainder of 65.
The next digit of our result is 3. 
Result so far: 53.0
The remainder is 65 after subtracting 240 from 305.
Include the next digit (1) from the dividend after 65, then repeat: 651 / 80

Going ahead to step 5:
80 goes into 651 8 times with a remainder of 11.
The next digit of our result is 8. 
Result so far: 538.0
Subtracting 640 from 651 leaves us with 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 80

Going ahead to step 6:
80 goes into 118 1 times with a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 5381.0
Subtracting 80 from 118 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 7:
When dividing 380 by 80, we get 4 with a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 5381.4
Deduct 320 from 380 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
The number 80 fits into 600 7 times, leaving a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 5381.47
Deduct 560 from 600 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.

Advancing to step 9:
400 divided by 80 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5381.475
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.

Advancing to step 10:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5381.475
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.

On to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 5381.475
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 5381.475 and a remainder of 0.0.
