863035 divided by 80 
The aim is to understand the frequency of 80 in 863035.

Going ahead to step 1:
When dividing 8 by 80, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 80

Going ahead to step 2:
80 can be fit into 86 1 times, resulting in a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 80 from 86, we get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 80

Moving on to step 3:
When dividing 63 by 80, we get 0 with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 63, we end up with 63.
Include the next digit (0) from the dividend after 63, then repeat: 630 / 80

Step 4:
80 goes into 630 7 times with a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
If we take 560 away from 630, we end up with 70.
Fetch the next digit (3) from the dividend, attach it to 70 and continue: 703 / 80

Moving on to step 5:
The number 80 fits into 703 8 times, leaving a remainder of 63.
Use 8 as the next digit of our solution. 
Result so far: 1078.0
Subtract 640 from 703 to get 63.
Take the next digit (5) from the dividend and append it to 63, then repeat: 635 / 80

Let's proceed to step 6:
The number 80 fits into 635 7 times, leaving a remainder of 75.
Write down 7 as next digit of the result. 
Result so far: 10787.0
If we subtract 560 from 635, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 7:
750 divided by 80 is 9 with a remainder of 30.
The next digit of our result is 9. 
Result so far: 10787.9
If we take 720 away from 750, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
If we divide 300 by 80, we get 3 and a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 10787.93
Deduct 240 from 300 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
The number 80 fits into 600 7 times, leaving a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 10787.937
If we take 560 away from 600, 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.

Advancing to step 10:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 10787.9375
The remainder is 0 after subtracting 400 from 400.
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 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10787.9375
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.

On to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10787.9375
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.

Our division results in 10787.9375 with a remaining 0.0.
