109150 ÷ 80 
The aim is to understand the frequency of 80 in 109150.

Moving on to step 1:
When dividing 1 by 80, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 80

On to step 2:
10 divided by 80 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 80

Let's proceed to step 3:
80 goes into 109 1 times with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 29 after subtracting 80 from 109.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 80

Going ahead to step 4:
80 goes into 291 3 times with a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 240 from 291 and we're left with 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 80

Step 5:
80 can be fit into 515 6 times, resulting in a remainder of 35.
Put 6 as the next digit of the answer. 
Result so far: 136.0
Subtract 480 from 515 to get 35.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 80

Moving on to step 6:
When dividing 350 by 80, we get 4 with a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 1364.0
If we subtract 320 from 350, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
The number 80 fits into 300 3 times, leaving a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 1364.3
If we subtract 240 from 300, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 8:
If we divide 600 by 80, we get 7 and a remainder of 40.
The next digit of our result is 7. 
Result so far: 1364.37
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
When dividing 400 by 80, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1364.375
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.

Advancing to step 10:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1364.375
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.

On to step 11:
80 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1364.375
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 1364.375, with a leftover of 0.0.
