814906 divided by 80 
The aim is to understand the frequency of 80 in 814906.

Let's proceed to 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
If we take 0 away from 8, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 80

Let's proceed to step 2:
80 goes into 81 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 1 after subtracting 80 from 81.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 80

On to step 3:
The number 80 fits into 14 0 times, leaving a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 14 and we're left with 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 80

Step 4:
149 divided by 80 is 1 with a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 101.0
The remainder is 69 after subtracting 80 from 149.
Grab the next digit (0) from the dividend, add it to 69, then carry on: 690 / 80

On to step 5:
80 goes into 690 8 times with a remainder of 50.
Use 8 as the next digit of our solution. 
Result so far: 1018.0
Subtract 640 from 690 to get 50.
Bring next digit (6) of the dividend behind the 50 and repeat the process: 506 / 80

Going ahead to step 6:
80 can be fit into 506 6 times, resulting in a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 10186.0
If we subtract 480 from 506, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 7:
80 can be fit into 260 3 times, resulting in a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 10186.3
Subtracting 240 from 260 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.

Let's proceed to step 8:
80 goes into 200 2 times with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 10186.32
If we take 160 away from 200, 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.

Step 9:
If we divide 400 by 80, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 10186.325
Deduct 400 from 400 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 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10186.325
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.

Going ahead to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10186.325
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.

The final outcome is 10186.325, with a leftover of 0.0.
