Let's divide 54358 by 84
The aim is to understand the frequency of 84 in 54358.

Step 1:
When dividing 5 by 84, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 84

Moving on to step 2:
54 divided by 84 is 0 with a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Include the next digit (3) from the dividend after 54, then repeat: 543 / 84

Step 3:
If we divide 543 by 84, we get 6 and a remainder of 39.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 504 from 543 to get 39.
Grab the next digit (5) from the dividend, add it to 39, then carry on: 395 / 84

Going ahead to step 4:
The number 84 fits into 395 4 times, leaving a remainder of 59.
Put 4 as the next digit of the answer. 
Result so far: 64.0
Deduct 336 from 395 and we're left with 59.
Take the next digit (8) from the dividend and append it to 59, then repeat: 598 / 84

Let's proceed to step 5:
When dividing 598 by 84, we get 7 with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 647.0
Deduct 588 from 598 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 6:
84 goes into 100 1 times with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 647.1
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
160 divided by 84 is 1 with a remainder of 76.
Put 1 as the next digit of the answer. 
Result so far: 647.11
Deduct 84 from 160 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

After the division, we end up with 647.11 and a remainder of 0.076.
