230449 ÷ 80 
The aim is to understand the frequency of 80 in 230449.

Let's proceed to step 1:
If we divide 2 by 80, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 80

Moving on to step 2:
80 can be fit into 23 0 times, resulting in a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Grab the next digit (0) from the dividend, add it to 23, then carry on: 230 / 80

Let's proceed to step 3:
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: 2.0
If we subtract 160 from 230, we get 70.
Bring next digit (4) of the dividend behind the 70 and repeat the process: 704 / 80

Moving on to step 4:
When dividing 704 by 80, we get 8 with a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtracting 640 from 704 leaves us with 64.
Append the next digit (4) from the dividend to 64 and continue with: 644 / 80

Let's proceed to step 5:
The number 80 fits into 644 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 288.0
Subtract 640 from 644 to get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 80

Moving on to step 6:
If we divide 49 by 80, we get 0 and a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 2880.0
The remainder is 49 after subtracting 0 from 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 7:
If we divide 490 by 80, we get 6 and a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 2880.6
Deduct 480 from 490 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
100 divided by 80 is 1 with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 2880.61
Subtracting 80 from 100 leaves us 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 9:
If we divide 200 by 80, we get 2 and a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 2880.612
Subtract 160 from 200 to get 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 10:
80 goes into 400 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 2880.6125
Subtract 400 from 400 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.

On to step 11:
0 divided by 80 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2880.6125
Deduct 0 from 0 and we're left 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.

Let's proceed to step 12:
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: 2880.6125
Deduct 0 from 0 and we're left 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.

The final result is 2880.6125 with a remainder of 0.0.
