215490 ÷ 84 
The aim is to understand the frequency of 84 in 215490.

Step 1:
84 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 84

Let's proceed to step 2:
84 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 84

On to step 3:
The number 84 fits into 215 2 times, leaving a remainder of 47.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 168 from 215 and we're left with 47.
Take the next digit (4) from the dividend and append it to 47, then repeat: 474 / 84

On to step 4:
If we divide 474 by 84, we get 5 and a remainder of 54.
The next digit of our result is 5. 
Result so far: 25.0
The remainder is 54 after subtracting 420 from 474.
Append the next digit (9) from the dividend to 54 and continue with: 549 / 84

Going ahead to step 5:
If we divide 549 by 84, we get 6 and a remainder of 45.
Record the quotient 6 as the next digit in the result. 
Result so far: 256.0
Subtract 504 from 549 to get 45.
Include the next digit (0) from the dividend after 45, then repeat: 450 / 84

On to step 6:
450 divided by 84 is 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 2565.0
Subtracting 420 from 450 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 7:
300 divided by 84 is 3 with a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 2565.3
Deduct 252 from 300 and we're left 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.

Moving on to step 8:
When dividing 480 by 84, we get 5 with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 2565.35
Subtracting 420 from 480 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.

Step 9:
84 can be fit into 600 7 times, resulting in a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 2565.357
The remainder is 12 after subtracting 588 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
84 can be fit into 120 1 times, resulting in a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 2565.3571
If we subtract 84 from 120, we 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.

On to step 11:
If we divide 360 by 84, we get 4 and a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 2565.35714
Subtract 336 from 360 to get 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 12:
84 goes into 240 2 times with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 2565.357142
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 13:
84 goes into 720 8 times with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 2565.3571428
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.

Advancing to step 14:
If we divide 480 by 84, we get 5 and a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 2565.35714285
The remainder is 60 after subtracting 420 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 2565.35714285, and the remainder is 6e-08.
