825354 divided by 84 
The aim is to understand the frequency of 84 in 825354.

Advancing to step 1:
8 divided by 84 is 0 with 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.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 84

Moving on to step 2:
84 goes into 82 0 times with a remainder of 82.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 82 to get 82.
Append the next digit (5) from the dividend to 82 and continue with: 825 / 84

On to step 3:
825 divided by 84 is 9 with a remainder of 69.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 756 from 825 and we're left with 69.
Fetch the next digit (3) from the dividend, attach it to 69 and continue: 693 / 84

On to step 4:
When dividing 693 by 84, we get 8 with a remainder of 21.
Put 8 as the next digit of the answer. 
Result so far: 98.0
If we subtract 672 from 693, we get 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 84

On to step 5:
If we divide 215 by 84, we get 2 and a remainder of 47.
Put 2 as the next digit of the answer. 
Result so far: 982.0
Deduct 168 from 215 and we're left with 47.
Include the next digit (4) from the dividend after 47, then repeat: 474 / 84

Going ahead to step 6:
When dividing 474 by 84, we get 5 with a remainder of 54.
The number 5 becomes the next digit in our result. 
Result so far: 9825.0
If we take 420 away from 474, 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.

Moving on to step 7:
The number 84 fits into 540 6 times, leaving a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 9825.6
The remainder is 36 after subtracting 504 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 8:
The number 84 fits into 360 4 times, leaving a remainder of 24.
The next digit of our result is 4. 
Result so far: 9825.64
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
84 goes into 240 2 times with a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 9825.642
Subtract 168 from 240 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 10:
If we divide 720 by 84, we get 8 and a remainder of 48.
The next digit of our result is 8. 
Result so far: 9825.6428
Subtracting 672 from 720 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
When dividing 480 by 84, we get 5 with a remainder of 60.
The next digit of our result is 5. 
Result so far: 9825.64285
Deduct 420 from 480 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
600 divided by 84 is 7 with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 9825.642857
The remainder is 12 after subtracting 588 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
84 can be fit into 120 1 times, resulting in a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 9825.6428571
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 14:
The number 84 fits into 360 4 times, leaving a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 9825.64285714
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 9825.64285714 with a remaining 2.4e-08.
