340230 ÷ 84 
The aim is to understand the frequency of 84 in 340230.

Going ahead to step 1:
3 divided by 84 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 84

Advancing to step 2:
84 goes into 34 0 times with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Bring next digit (0) of the dividend behind the 34 and repeat the process: 340 / 84

On to step 3:
340 divided by 84 is 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 4 after subtracting 336 from 340.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 84

Advancing to step 4:
84 can be fit into 42 0 times, resulting in a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Deduct 0 from 42 and we're left with 42.
Append the next digit (3) from the dividend to 42 and continue with: 423 / 84

Step 5:
The number 84 fits into 423 5 times, leaving a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 405.0
The remainder is 3 after subtracting 420 from 423.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 84

Advancing to step 6:
If we divide 30 by 84, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 4050.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 7:
If we divide 300 by 84, we get 3 and a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 4050.3
The remainder is 48 after subtracting 252 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 8:
The number 84 fits into 480 5 times, leaving a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 4050.35
If we subtract 420 from 480, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
600 divided by 84 is 7 with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 4050.357
If we subtract 588 from 600, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
84 can be fit into 120 1 times, resulting in a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 4050.3571
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 11:
The number 84 fits into 360 4 times, leaving a remainder of 24.
The next digit of our result is 4. 
Result so far: 4050.35714
Subtracting 336 from 360 leaves us 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.

Going ahead to step 12:
The number 84 fits into 240 2 times, leaving a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 4050.357142
Deduct 168 from 240 and we're left with 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 13:
84 goes into 720 8 times with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 4050.3571428
Subtract 672 from 720 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 14:
If we divide 480 by 84, we get 5 and a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 4050.35714285
Subtract 420 from 480 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 4050.35714285 and a remainder of 6e-08.
