We divide 839481 by 80
The aim is to understand the frequency of 80 in 839481.

Step 1:
If we divide 8 by 80, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 80

Let's proceed to step 2:
The number 80 fits into 83 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 80 from 83 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 80

Step 3:
The number 80 fits into 39 0 times, leaving a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 39, we get 39.
Include the next digit (4) from the dividend after 39, then repeat: 394 / 80

Going ahead to step 4:
80 goes into 394 4 times with a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
If we take 320 away from 394, we end up with 74.
Take the next digit (8) from the dividend and append it to 74, then repeat: 748 / 80

Let's proceed to step 5:
80 goes into 748 9 times with a remainder of 28.
The next digit of our result is 9. 
Result so far: 1049.0
The remainder is 28 after subtracting 720 from 748.
Take the next digit (1) from the dividend and append it to 28, then repeat: 281 / 80

Step 6:
When dividing 281 by 80, we get 3 with a remainder of 41.
The next digit of our result is 3. 
Result so far: 10493.0
Subtract 240 from 281 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 7:
80 can be fit into 410 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 10493.5
If we take 400 away from 410, we end up 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: 10493.51
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.

Advancing to step 9:
When dividing 200 by 80, we get 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 10493.512
Subtracting 160 from 200 leaves us 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.

Moving on 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: 10493.5125
If we take 400 away from 400, 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.

Moving on to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 10493.5125
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.

Let's proceed to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10493.5125
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.

Our division results in 10493.5125 with a remaining 0.0.
