Let's divide 800857 by 80
The aim is to understand the frequency of 80 in 800857.

Going ahead to step 1:
8 divided by 80 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 80

Moving on to step 2:
80 can be fit into 80 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 0 after subtracting 80 from 80.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 80

Let's proceed to step 3:
80 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 0 after subtracting 0 from 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 80

Let's proceed to step 4:
If we divide 8 by 80, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 100.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 80

Advancing to step 5:
When dividing 85 by 80, we get 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1001.0
If we subtract 80 from 85, we get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 80

Going ahead to step 6:
When dividing 57 by 80, we get 0 with a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 10010.0
The remainder is 57 after subtracting 0 from 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 7:
When dividing 570 by 80, we get 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 10010.7
Deduct 560 from 570 and we're left 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.

Advancing to step 8:
80 can be fit into 100 1 times, resulting in a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 10010.71
Deduct 80 from 100 and we're left 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.

Step 9:
200 divided by 80 is 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 10010.712
Deduct 160 from 200 and we're left 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.

Going ahead to step 10:
400 divided by 80 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 10010.7125
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.

Let's proceed to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 10010.7125
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 12:
0 divided by 80 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10010.7125
Subtracting 0 from 0 leaves us 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.

The quotient of the division is 10010.7125, and the remainder is 0.0.
