We divide 1234 by 80
The aim is to understand the frequency of 80 in 1234.

Going ahead to step 1:
1 divided by 80 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 80

On to step 2:
80 can be fit into 12 0 times, resulting in a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 80

Let's proceed to step 3:
If we divide 123 by 80, we get 1 and a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 80 from 123 to get 43.
Grab the next digit (4) from the dividend, add it to 43, then carry on: 434 / 80

Let's proceed to step 4:
434 divided by 80 is 5 with a remainder of 34.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 400 from 434, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 5:
80 can be fit into 340 4 times, resulting in a remainder of 20.
The next digit of our result is 4. 
Result so far: 15.4
If we take 320 away from 340, we end up 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.

Going ahead to step 6:
When dividing 200 by 80, we get 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 15.42
Subtracting 160 from 200 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.

Advancing to step 7:
80 can be fit into 400 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 15.425
If we subtract 400 from 400, 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 8:
0 divided by 80 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15.425
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.

Going ahead to step 9:
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: 15.425
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.

Our division results in 15.425 with a remaining 0.0.
