135284 divided by 84 
The aim is to understand the frequency of 84 in 135284.

Advancing to step 1:
The number 84 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 84

Going ahead to step 2:
84 goes into 13 0 times with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 84

Step 3:
The number 84 fits into 135 1 times, leaving a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 84 from 135, we get 51.
Append the next digit (2) from the dividend to 51 and continue with: 512 / 84

Going ahead to step 4:
84 can be fit into 512 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 504 away from 512, we end up with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 84

Going ahead to step 5:
84 can be fit into 88 1 times, resulting in a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 161.0
The remainder is 4 after subtracting 84 from 88.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 84

Let's proceed to step 6:
84 goes into 44 0 times with a remainder of 44.
Use 0 as the next digit of our solution. 
Result so far: 1610.0
If we take 0 away from 44, 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.

Step 7:
84 goes into 440 5 times with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 1610.5
Subtracting 420 from 440 leaves us 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 8:
200 divided by 84 is 2 with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 1610.52
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.

On to step 9:
84 can be fit into 320 3 times, resulting in a remainder of 68.
The number 3 becomes the next digit in our result. 
Result so far: 1610.523
Subtract 252 from 320 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 10:
84 can be fit into 680 8 times, resulting in a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 1610.5238
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.

Advancing to step 11:
84 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 1610.5238
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.

Step 12:
When dividing 800 by 84, we get 9 with a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 1610.523809
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.

Let's proceed to step 13:
440 divided by 84 is 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 1610.5238095
If we take 420 away from 440, we end up 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 14:
If we divide 200 by 84, we get 2 and a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 1610.52380952
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.

The final result is 1610.52380952 with a remainder of 3.2e-08.
