82811 ÷ 84 
The aim is to understand the frequency of 84 in 82811.

On to step 1:
When dividing 8 by 84, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 84

Step 2:
The number 84 fits into 82 0 times, leaving a remainder of 82.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 82, we end up with 82.
Fetch the next digit (8) from the dividend, attach it to 82 and continue: 828 / 84

Moving on to step 3:
If we divide 828 by 84, we get 9 and a remainder of 72.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 756 from 828, we get 72.
Append the next digit (1) from the dividend to 72 and continue with: 721 / 84

Step 4:
84 goes into 721 8 times with a remainder of 49.
The next digit of our result is 8. 
Result so far: 98.0
If we take 672 away from 721, we end up with 49.
Append the next digit (1) from the dividend to 49 and continue with: 491 / 84

On to step 5:
84 can be fit into 491 5 times, resulting in a remainder of 71.
The next digit of our result is 5. 
Result so far: 985.0
Subtract 420 from 491 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 6:
710 divided by 84 is 8 with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 985.8
Subtracting 672 from 710 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 7:
If we divide 380 by 84, we get 4 and a remainder of 44.
The next digit of our result is 4. 
Result so far: 985.84
If we subtract 336 from 380, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 8:
440 divided by 84 is 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 985.845
Deduct 420 from 440 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.

Going ahead to step 9:
The number 84 fits into 200 2 times, leaving a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 985.8452
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
84 goes into 320 3 times with a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 985.84523
The remainder is 68 after subtracting 252 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 11:
84 goes into 680 8 times with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 985.845238
The remainder is 8 after subtracting 672 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
84 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 985.845238
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
84 goes into 800 9 times with a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 985.84523809
The remainder is 44 after subtracting 756 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 985.84523809 and a remainder of 4.4e-08.
