369186 ÷ 84 
The aim is to understand the frequency of 84 in 369186.

Going ahead to step 1:
The number 84 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 84

Moving on to step 2:
84 can be fit into 36 0 times, resulting in a remainder of 36.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Include the next digit (9) from the dividend after 36, then repeat: 369 / 84

Moving on to step 3:
84 can be fit into 369 4 times, resulting in a remainder of 33.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 336 from 369 and we're left with 33.
Bring next digit (1) of the dividend behind the 33 and repeat the process: 331 / 84

Step 4:
84 can be fit into 331 3 times, resulting in a remainder of 79.
Write down 3 as next digit of the result. 
Result so far: 43.0
Subtract 252 from 331 to get 79.
Fetch the next digit (8) from the dividend, attach it to 79 and continue: 798 / 84

Advancing to step 5:
If we divide 798 by 84, we get 9 and a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 439.0
Subtracting 756 from 798 leaves us with 42.
Fetch the next digit (6) from the dividend, attach it to 42 and continue: 426 / 84

Going ahead to step 6:
84 can be fit into 426 5 times, resulting in a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 4395.0
Subtracting 420 from 426 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
The number 84 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 4395.0
If we take 0 away from 60, 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.

Going ahead to step 8:
When dividing 600 by 84, we get 7 with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 4395.07
If we take 588 away from 600, we end up 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.

Let's proceed to step 9:
120 divided by 84 is 1 with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 4395.071
Subtract 84 from 120 to get 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 10:
If we divide 360 by 84, we get 4 and a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 4395.0714
If we take 336 away from 360, we end up 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:
The number 84 fits into 240 2 times, leaving a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 4395.07142
Deduct 168 from 240 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 12:
When dividing 720 by 84, we get 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 4395.071428
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.

Moving on to step 13:
84 goes into 480 5 times with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 4395.0714285
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.

Let's proceed to step 14:
84 goes into 600 7 times with a remainder of 12.
The next digit of our result is 7. 
Result so far: 4395.07142857
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.

After the division, we end up with 4395.07142857 and a remainder of 1.2e-08.
