We're dividing 338530 by 80 
The aim is to understand the frequency of 80 in 338530.

Let's proceed to step 1:
If we divide 3 by 80, we get 0 and 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.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 80

Advancing to step 2:
The number 80 fits into 33 0 times, leaving a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Include the next digit (8) from the dividend after 33, then repeat: 338 / 80

Step 3:
80 can be fit into 338 4 times, resulting in a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 18 after subtracting 320 from 338.
Append the next digit (5) from the dividend to 18 and continue with: 185 / 80

Let's proceed to step 4:
The number 80 fits into 185 2 times, leaving a remainder of 25.
The next digit of our result is 2. 
Result so far: 42.0
If we subtract 160 from 185, we get 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 80

On to step 5:
253 divided by 80 is 3 with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 423.0
If we take 240 away from 253, we end up with 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 80

On to step 6:
When dividing 130 by 80, we get 1 with a remainder of 50.
Put 1 as the next digit of the answer. 
Result so far: 4231.0
The remainder is 50 after subtracting 80 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 7:
80 goes into 500 6 times with a remainder of 20.
The next digit of our result is 6. 
Result so far: 4231.6
Deduct 480 from 500 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
When dividing 200 by 80, we get 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 4231.62
The remainder is 40 after subtracting 160 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
400 divided by 80 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 4231.625
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.

Step 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4231.625
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.

Moving on to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4231.625
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.

The quotient of the division is 4231.625, and the remainder is 0.0.
