856211 divided by 80 
The aim is to understand the frequency of 80 in 856211.

Going ahead to step 1:
80 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 80

Let's proceed to step 2:
If we divide 85 by 80, we get 1 and a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 80 away from 85, we end up with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 80

On to step 3:
If we divide 56 by 80, we get 0 and a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 56, we end up with 56.
Grab the next digit (2) from the dividend, add it to 56, then carry on: 562 / 80

Moving on to step 4:
80 can be fit into 562 7 times, resulting in a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 107.0
Subtracting 560 from 562 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 80

Let's proceed to step 5:
When dividing 21 by 80, we get 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 1070.0
If we subtract 0 from 21, we get 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 80

Let's proceed to step 6:
80 can be fit into 211 2 times, resulting in a remainder of 51.
The number 2 becomes the next digit in our result. 
Result so far: 10702.0
Subtracting 160 from 211 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 7:
80 goes into 510 6 times with a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 10702.6
Subtract 480 from 510 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
The number 80 fits into 300 3 times, leaving a remainder of 60.
The next digit of our result is 3. 
Result so far: 10702.63
Subtract 240 from 300 to 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.

On to step 9:
If we divide 600 by 80, we get 7 and a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 10702.637
If we subtract 560 from 600, we get 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 10:
80 goes into 400 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 10702.6375
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.

Step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10702.6375
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.

Let's proceed to step 12:
80 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10702.6375
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 10702.6375, and the remainder is 0.0.
