301430 ÷ 84 
The aim is to understand the frequency of 84 in 301430.

Moving on to step 1:
84 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 84

On to step 2:
When dividing 30 by 84, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 84

Advancing to step 3:
When dividing 301 by 84, we get 3 with a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 252 from 301, we get 49.
Append the next digit (4) from the dividend to 49 and continue with: 494 / 84

Advancing to step 4:
If we divide 494 by 84, we get 5 and a remainder of 74.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Subtract 420 from 494 to get 74.
Take the next digit (3) from the dividend and append it to 74, then repeat: 743 / 84

Let's proceed to step 5:
The number 84 fits into 743 8 times, leaving a remainder of 71.
The number 8 becomes the next digit in our result. 
Result so far: 358.0
If we subtract 672 from 743, we get 71.
Bring next digit (0) of the dividend behind the 71 and repeat the process: 710 / 84

Going ahead to step 6:
If we divide 710 by 84, we get 8 and a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 3588.0
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.

Step 7:
84 can be fit into 380 4 times, resulting in a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 3588.4
Deduct 336 from 380 and we're left 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.

On to step 8:
The number 84 fits into 440 5 times, leaving a remainder of 20.
The next digit of our result is 5. 
Result so far: 3588.45
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.

Let's proceed to step 9:
When dividing 200 by 84, we get 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 3588.452
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 10:
320 divided by 84 is 3 with a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 3588.4523
If we take 252 away from 320, we end up 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 11:
680 divided by 84 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 3588.45238
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 can be fit into 80 0 times, resulting in a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 3588.45238
If we subtract 0 from 80, we 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.

Let's proceed to step 13:
84 goes into 800 9 times with a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 3588.4523809
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.

Advancing to step 14:
When dividing 440 by 84, we get 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 3588.45238095
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.

The final outcome is 3588.45238095, with a leftover of 2e-08.
