849254 ÷ 80 
The aim is to understand the frequency of 80 in 849254.

Let's proceed to step 1:
The number 80 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 80

Step 2:
80 can be fit into 84 1 times, resulting in a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 80 from 84 and we're left with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 80

Let's proceed to step 3:
49 divided by 80 is 0 with a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 49 and we're left with 49.
Bring next digit (2) of the dividend behind the 49 and repeat the process: 492 / 80

Going ahead to step 4:
The number 80 fits into 492 6 times, leaving a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 106.0
The remainder is 12 after subtracting 480 from 492.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 80

On to step 5:
If we divide 125 by 80, we get 1 and a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 1061.0
Subtract 80 from 125 to get 45.
Include the next digit (4) from the dividend after 45, then repeat: 454 / 80

On to step 6:
80 goes into 454 5 times with a remainder of 54.
Put 5 as the next digit of the answer. 
Result so far: 10615.0
If we take 400 away from 454, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 7:
540 divided by 80 is 6 with a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 10615.6
If we subtract 480 from 540, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
If we divide 600 by 80, we get 7 and a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 10615.67
The remainder is 40 after subtracting 560 from 600.
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 9:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 10615.675
Subtracting 400 from 400 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.

Step 10:
0 divided by 80 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10615.675
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 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10615.675
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 10615.675 and a remainder of 0.0.
