We're dividing 258273 by 80 
The aim is to understand the frequency of 80 in 258273.

Let's proceed to step 1:
80 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 80

Moving on to step 2:
If we divide 25 by 80, we get 0 and a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 80

On to step 3:
80 goes into 258 3 times with a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 240 away from 258, we end up with 18.
Take the next digit (2) from the dividend and append it to 18, then repeat: 182 / 80

Step 4:
When dividing 182 by 80, we get 2 with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 32.0
Subtracting 160 from 182 leaves us with 22.
Append the next digit (7) from the dividend to 22 and continue with: 227 / 80

Advancing to step 5:
When dividing 227 by 80, we get 2 with a remainder of 67.
Record the quotient 2 as the next digit in the result. 
Result so far: 322.0
Subtract 160 from 227 to get 67.
Append the next digit (3) from the dividend to 67 and continue with: 673 / 80

Step 6:
80 goes into 673 8 times with a remainder of 33.
Use 8 as the next digit of our solution. 
Result so far: 3228.0
If we subtract 640 from 673, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 7:
When dividing 330 by 80, we get 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 3228.4
Deduct 320 from 330 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.

Step 8:
When dividing 100 by 80, we get 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 3228.41
Subtract 80 from 100 to get 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 9:
80 can be fit into 200 2 times, resulting in a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 3228.412
Deduct 160 from 200 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 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 3228.4125
Deduct 400 from 400 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.

On to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3228.4125
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 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3228.4125
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.

The final outcome is 3228.4125, with a leftover of 0.0.
