254188 divided by 80 
The aim is to understand the frequency of 80 in 254188.

On to step 1:
2 divided by 80 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 80

Let's proceed to step 2:
25 divided by 80 is 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 80

Step 3:
The number 80 fits into 254 3 times, leaving a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 240 from 254 and we're left with 14.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 80

Going ahead to step 4:
If we divide 141 by 80, we get 1 and a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 31.0
The remainder is 61 after subtracting 80 from 141.
Bring next digit (8) of the dividend behind the 61 and repeat the process: 618 / 80

On to step 5:
The number 80 fits into 618 7 times, leaving a remainder of 58.
Record the quotient 7 as the next digit in the result. 
Result so far: 317.0
Subtract 560 from 618 to get 58.
Take the next digit (8) from the dividend and append it to 58, then repeat: 588 / 80

Step 6:
588 divided by 80 is 7 with a remainder of 28.
Record the quotient 7 as the next digit in the result. 
Result so far: 3177.0
If we subtract 560 from 588, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 7:
The number 80 fits into 280 3 times, leaving a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 3177.3
If we take 240 away from 280, we end up 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.

Let's proceed to step 8:
When dividing 400 by 80, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 3177.35
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.

Advancing 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: 3177.35
If we subtract 0 from 0, 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.

Going ahead to step 10:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3177.35
Subtracting 0 from 0 leaves us 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 3177.35 with a remaining 0.0.
