54589 ÷ 84 
The aim is to understand the frequency of 84 in 54589.

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.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 84

Let's proceed to step 2:
When dividing 54 by 84, we get 0 with a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Grab the next digit (5) from the dividend, add it to 54, then carry on: 545 / 84

Let's proceed to step 3:
If we divide 545 by 84, we get 6 and a remainder of 41.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 504 away from 545, we end up with 41.
Append the next digit (8) from the dividend to 41 and continue with: 418 / 84

Let's proceed to step 4:
84 can be fit into 418 4 times, resulting in a remainder of 82.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
The remainder is 82 after subtracting 336 from 418.
Include the next digit (9) from the dividend after 82, then repeat: 829 / 84

Step 5:
When dividing 829 by 84, we get 9 with a remainder of 73.
Write down 9 as next digit of the result. 
Result so far: 649.0
If we subtract 756 from 829, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 6:
When dividing 730 by 84, we get 8 with a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 649.8
If we take 672 away from 730, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 7:
84 goes into 580 6 times with a remainder of 76.
The number 6 becomes the next digit in our result. 
Result so far: 649.86
Subtracting 504 from 580 leaves us 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.

Going ahead to step 8:
If we divide 760 by 84, we get 9 and a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 649.869
Subtracting 756 from 760 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
If we divide 40 by 84, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 649.869
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
84 can be fit into 400 4 times, resulting in a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 649.86904
Deduct 336 from 400 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 11:
When dividing 640 by 84, we get 7 with a remainder of 52.
Record the quotient 7 as the next digit in the result. 
Result so far: 649.869047
The remainder is 52 after subtracting 588 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 12:
84 can be fit into 520 6 times, resulting in a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 649.8690476
Subtract 504 from 520 to get 16.
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 13:
If we divide 160 by 84, we get 1 and a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 649.86904761
If we subtract 84 from 160, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 649.86904761, with a leftover of 7.6e-08.
