281804 divided by 84 
The aim is to understand the frequency of 84 in 281804.

Step 1:
The number 84 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 84

Let's proceed to step 2:
28 divided by 84 is 0 with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Take the next digit (1) from the dividend and append it to 28, then repeat: 281 / 84

Let's proceed to step 3:
84 goes into 281 3 times with a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 252 from 281 to get 29.
Fetch the next digit (8) from the dividend, attach it to 29 and continue: 298 / 84

Let's proceed to step 4:
84 goes into 298 3 times with a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
Subtract 252 from 298 to get 46.
Append the next digit (0) from the dividend to 46 and continue with: 460 / 84

Advancing to step 5:
460 divided by 84 is 5 with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 335.0
If we take 420 away from 460, we end up with 40.
Include the next digit (4) from the dividend after 40, then repeat: 404 / 84

On to step 6:
The number 84 fits into 404 4 times, leaving a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 3354.0
The remainder is 68 after subtracting 336 from 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 7:
680 divided by 84 is 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 3354.8
If we subtract 672 from 680, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
When dividing 80 by 84, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 3354.8
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 9:
84 can be fit into 800 9 times, resulting in a remainder of 44.
The next digit of our result is 9. 
Result so far: 3354.809
If we take 756 away from 800, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 10:
440 divided by 84 is 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 3354.8095
Subtract 420 from 440 to get 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 11:
84 can be fit into 200 2 times, resulting in a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 3354.80952
The remainder is 32 after subtracting 168 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
84 goes into 320 3 times with a remainder of 68.
The next digit of our result is 3. 
Result so far: 3354.809523
Subtracting 252 from 320 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 13:
84 goes into 680 8 times with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 3354.8095238
Subtracting 672 from 680 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
The number 84 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 3354.8095238
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 3354.8095238, with a leftover of 8e-08.
