We're dividing 544121 by 84 
The aim is to understand the frequency of 84 in 544121.

Advancing to step 1:
84 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 84

On to step 2:
If we divide 54 by 84, we get 0 and a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Bring next digit (4) of the dividend behind the 54 and repeat the process: 544 / 84

Moving on to step 3:
84 can be fit into 544 6 times, resulting in a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 504 from 544 and we're left with 40.
Bring next digit (1) of the dividend behind the 40 and repeat the process: 401 / 84

Moving on to step 4:
401 divided by 84 is 4 with a remainder of 65.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
Deduct 336 from 401 and we're left with 65.
Append the next digit (2) from the dividend to 65 and continue with: 652 / 84

On to step 5:
84 goes into 652 7 times with a remainder of 64.
Use 7 as the next digit of our solution. 
Result so far: 647.0
If we subtract 588 from 652, we get 64.
Bring next digit (1) of the dividend behind the 64 and repeat the process: 641 / 84

Step 6:
If we divide 641 by 84, we get 7 and a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 6477.0
Deduct 588 from 641 and we're left 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.

Going ahead to step 7:
The number 84 fits into 530 6 times, leaving a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 6477.6
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.

On to step 8:
260 divided by 84 is 3 with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 6477.63
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:
84 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 6477.63
Subtract 0 from 80 to 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:
The number 84 fits into 800 9 times, leaving a remainder of 44.
The next digit of our result is 9. 
Result so far: 6477.6309
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.

Going ahead to step 11:
84 goes into 440 5 times with a remainder of 20.
The next digit of our result is 5. 
Result so far: 6477.63095
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:
84 can be fit into 200 2 times, resulting in a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 6477.630952
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.

Going ahead to step 13:
The number 84 fits into 320 3 times, leaving a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 6477.6309523
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 14:
If we divide 680 by 84, we get 8 and a remainder of 8.
The next digit of our result is 8. 
Result so far: 6477.63095238
Deduct 672 from 680 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.

In conclusion, the division gives 6477.63095238 with a balance of 8e-09.
