806736 divided by 80 
The aim is to understand the frequency of 80 in 806736.

Step 1:
If we divide 8 by 80, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 80

Advancing to step 2:
When dividing 80 by 80, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 80 from 80 leaves us with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 80

Going ahead to step 3:
80 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 80

Advancing to step 4:
80 can be fit into 67 0 times, resulting in a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 100.0
If we subtract 0 from 67, we get 67.
Grab the next digit (3) from the dividend, add it to 67, then carry on: 673 / 80

Advancing to step 5:
If we divide 673 by 80, we get 8 and a remainder of 33.
The next digit of our result is 8. 
Result so far: 1008.0
If we subtract 640 from 673, we get 33.
Take the next digit (6) from the dividend and append it to 33, then repeat: 336 / 80

On to step 6:
The number 80 fits into 336 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 10084.0
The remainder is 16 after subtracting 320 from 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
If we divide 160 by 80, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 10084.2
If we subtract 160 from 160, 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.

Step 8:
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: 10084.2
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.

Advancing to step 9:
80 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10084.2
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 10084.2 and a remainder of 0.0.
