We're dividing 189594 by 84 
The aim is to understand the frequency of 84 in 189594.

Going ahead to step 1:
1 divided by 84 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 84

Advancing to step 2:
When dividing 18 by 84, we get 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 84

Moving on to step 3:
The number 84 fits into 189 2 times, leaving a remainder of 21.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 168 from 189 leaves us with 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 84

On to step 4:
84 goes into 215 2 times with a remainder of 47.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Subtract 168 from 215 to get 47.
Fetch the next digit (9) from the dividend, attach it to 47 and continue: 479 / 84

Step 5:
If we divide 479 by 84, we get 5 and a remainder of 59.
The number 5 becomes the next digit in our result. 
Result so far: 225.0
Subtract 420 from 479 to get 59.
Include the next digit (4) from the dividend after 59, then repeat: 594 / 84

Moving on to step 6:
If we divide 594 by 84, we get 7 and a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 2257.0
Subtract 588 from 594 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
If we divide 60 by 84, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 2257.0
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
When dividing 600 by 84, we get 7 with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 2257.07
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 9:
If we divide 120 by 84, we get 1 and a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 2257.071
If we take 84 away from 120, we end up with 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 10:
84 goes into 360 4 times with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 2257.0714
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 11:
84 goes into 240 2 times with a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 2257.07142
If we subtract 168 from 240, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 12:
If we divide 720 by 84, we get 8 and a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 2257.071428
If we subtract 672 from 720, we 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.

On to step 13:
84 goes into 480 5 times with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 2257.0714285
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.

Step 14:
600 divided by 84 is 7 with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 2257.07142857
Deduct 588 from 600 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 2257.07142857 with a remaining 1.2e-08.
