We look at the division of 542945 by 84 
The aim is to understand the frequency of 84 in 542945.

Moving on to step 1:
84 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 84

Going ahead to step 2:
84 can be fit into 54 0 times, resulting in a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Take the next digit (2) from the dividend and append it to 54, then repeat: 542 / 84

Moving on to step 3:
The number 84 fits into 542 6 times, leaving a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 504 from 542 to get 38.
Take the next digit (9) from the dividend and append it to 38, then repeat: 389 / 84

Let's proceed to step 4:
84 goes into 389 4 times with a remainder of 53.
Put 4 as the next digit of the answer. 
Result so far: 64.0
If we take 336 away from 389, we end up with 53.
Grab the next digit (4) from the dividend, add it to 53, then carry on: 534 / 84

Advancing to step 5:
534 divided by 84 is 6 with a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 646.0
If we subtract 504 from 534, we get 30.
Include the next digit (5) from the dividend after 30, then repeat: 305 / 84

On to step 6:
If we divide 305 by 84, we get 3 and a remainder of 53.
Put 3 as the next digit of the answer. 
Result so far: 6463.0
Subtracting 252 from 305 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 7:
530 divided by 84 is 6 with a remainder of 26.
The next digit of our result is 6. 
Result so far: 6463.6
If we take 504 away from 530, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 8:
84 can be fit into 260 3 times, resulting in a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 6463.63
Deduct 252 from 260 and we're left 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.

Moving on to step 9:
If we divide 80 by 84, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 6463.63
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.

On to step 10:
84 can be fit into 800 9 times, resulting in a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 6463.6309
Deduct 756 from 800 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.

Moving on to step 11:
When dividing 440 by 84, we get 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 6463.63095
Deduct 420 from 440 and we're left 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.

Let's proceed to step 12:
If we divide 200 by 84, we get 2 and a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 6463.630952
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.

Advancing to step 13:
84 can be fit into 320 3 times, resulting in a remainder of 68.
Use 3 as the next digit of our solution. 
Result so far: 6463.6309523
The remainder is 68 after subtracting 252 from 320.
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 14:
If we divide 680 by 84, we get 8 and a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 6463.63095238
Subtract 672 from 680 to 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.

The final result is 6463.63095238 with a remainder of 8e-09.
