We look at the division of 804113 by 80 
The aim is to understand the frequency of 80 in 804113.

Going ahead to step 1:
80 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 80

Advancing to step 2:
The number 80 fits into 80 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 0 after subtracting 80 from 80.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 80

On to step 3:
80 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 4, we end up with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 80

Moving on to step 4:
The number 80 fits into 41 0 times, leaving a remainder of 41.
The next digit of our result is 0. 
Result so far: 100.0
Deduct 0 from 41 and we're left with 41.
Bring next digit (1) of the dividend behind the 41 and repeat the process: 411 / 80

Advancing to step 5:
When dividing 411 by 80, we get 5 with a remainder of 11.
The next digit of our result is 5. 
Result so far: 1005.0
Deduct 400 from 411 and we're left with 11.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 80

Let's proceed to step 6:
113 divided by 80 is 1 with a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 10051.0
The remainder is 33 after subtracting 80 from 113.
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:
80 goes into 330 4 times with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 10051.4
The remainder is 10 after subtracting 320 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
The number 80 fits into 100 1 times, leaving a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 10051.41
If we subtract 80 from 100, we 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.

Step 9:
80 goes into 200 2 times with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 10051.412
If we subtract 160 from 200, we 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.

Step 10:
400 divided by 80 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 10051.4125
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 11:
0 divided by 80 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10051.4125
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.

On to step 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10051.4125
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.

Our division results in 10051.4125 with a remaining 0.0.
