We divide 87387 by 84
The aim is to understand the frequency of 84 in 87387.

Moving on to step 1:
When dividing 8 by 84, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 84

Moving on to step 2:
84 can be fit into 87 1 times, resulting in a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 84 from 87 leaves us with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 84

Let's proceed to step 3:
33 divided by 84 is 0 with a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 33 to get 33.
Append the next digit (8) from the dividend to 33 and continue with: 338 / 84

Step 4:
338 divided by 84 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 104.0
Subtract 336 from 338 to get 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 84

Let's proceed to step 5:
The number 84 fits into 27 0 times, leaving a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 1040.0
The remainder is 27 after subtracting 0 from 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 6:
84 can be fit into 270 3 times, resulting in a remainder of 18.
The next digit of our result is 3. 
Result so far: 1040.3
Subtracting 252 from 270 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
180 divided by 84 is 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 1040.32
If we subtract 168 from 180, 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 8:
If we divide 120 by 84, we get 1 and a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 1040.321
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.

Let's proceed to step 9:
84 goes into 360 4 times with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 1040.3214
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
240 divided by 84 is 2 with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 1040.32142
The remainder is 72 after subtracting 168 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 11:
84 can be fit into 720 8 times, resulting in a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 1040.321428
Subtracting 672 from 720 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 12:
480 divided by 84 is 5 with a remainder of 60.
The next digit of our result is 5. 
Result so far: 1040.3214285
If we take 420 away from 480, we end up 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.

Step 13:
600 divided by 84 is 7 with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 1040.32142857
Subtract 588 from 600 to 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.

Our division results in 1040.32142857 with a remaining 1.2e-08.
