We divide 209997 by 84
The aim is to understand the frequency of 84 in 209997.

Advancing to step 1:
2 divided by 84 is 0 with 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 (0) of the dividend behind the 2 and repeat the process: 20 / 84

Moving on to step 2:
When dividing 20 by 84, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Fetch the next digit (9) from the dividend, attach it to 20 and continue: 209 / 84

Moving on to step 3:
If we divide 209 by 84, we get 2 and a remainder of 41.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 168 from 209, we get 41.
Take the next digit (9) from the dividend and append it to 41, then repeat: 419 / 84

Moving on to step 4:
If we divide 419 by 84, we get 4 and a remainder of 83.
Put 4 as the next digit of the answer. 
Result so far: 24.0
The remainder is 83 after subtracting 336 from 419.
Bring next digit (9) of the dividend behind the 83 and repeat the process: 839 / 84

Step 5:
If we divide 839 by 84, we get 9 and a remainder of 83.
The number 9 becomes the next digit in our result. 
Result so far: 249.0
If we subtract 756 from 839, we get 83.
Grab the next digit (7) from the dividend, add it to 83, then carry on: 837 / 84

Step 6:
837 divided by 84 is 9 with a remainder of 81.
Write down 9 as next digit of the result. 
Result so far: 2499.0
If we take 756 away from 837, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 7:
84 can be fit into 810 9 times, resulting in a remainder of 54.
Record the quotient 9 as the next digit in the result. 
Result so far: 2499.9
Deduct 756 from 810 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 8:
When dividing 540 by 84, we get 6 with a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 2499.96
If we take 504 away from 540, 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:
If we divide 360 by 84, we get 4 and a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 2499.964
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.

Moving on to step 10:
84 goes into 240 2 times with a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 2499.9642
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.

On to step 11:
The number 84 fits into 720 8 times, leaving a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 2499.96428
The remainder is 48 after subtracting 672 from 720.
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 12:
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: 2499.964285
Deduct 420 from 480 and we're left 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 13:
If we divide 600 by 84, we get 7 and a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 2499.9642857
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.

Step 14:
If we divide 120 by 84, we get 1 and a remainder of 36.
The next digit of our result is 1. 
Result so far: 2499.96428571
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.

The final outcome is 2499.96428571, with a leftover of 3.6e-08.
