We're dividing 221120 by 84 
The aim is to understand the frequency of 84 in 221120.

Let's proceed to step 1:
If we divide 2 by 84, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 84

Moving on to step 2:
84 goes into 22 0 times with a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 22, we get 22.
Bring next digit (1) of the dividend behind the 22 and repeat the process: 221 / 84

Let's proceed to step 3:
84 can be fit into 221 2 times, resulting in a remainder of 53.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 168 from 221 and we're left with 53.
Append the next digit (1) from the dividend to 53 and continue with: 531 / 84

Advancing to step 4:
If we divide 531 by 84, we get 6 and a remainder of 27.
The next digit of our result is 6. 
Result so far: 26.0
Subtracting 504 from 531 leaves us with 27.
Bring next digit (2) of the dividend behind the 27 and repeat the process: 272 / 84

On to step 5:
272 divided by 84 is 3 with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 263.0
Subtracting 252 from 272 leaves us with 20.
Include the next digit (0) from the dividend after 20, then repeat: 200 / 84

Let's proceed to step 6:
The number 84 fits into 200 2 times, leaving a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 2632.0
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 7:
When dividing 320 by 84, we get 3 with a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 2632.3
If we subtract 252 from 320, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 8:
If we divide 680 by 84, we get 8 and a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 2632.38
If we subtract 672 from 680, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
84 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 2632.38
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 10:
The number 84 fits into 800 9 times, leaving a remainder of 44.
The number 9 becomes the next digit in our result. 
Result so far: 2632.3809
Deduct 756 from 800 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 11:
When dividing 440 by 84, we get 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 2632.38095
Subtracting 420 from 440 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
84 goes into 200 2 times with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 2632.380952
Subtracting 168 from 200 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 13:
If we divide 320 by 84, we get 3 and a remainder of 68.
The next digit of our result is 3. 
Result so far: 2632.3809523
If we subtract 252 from 320, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 14:
84 can be fit into 680 8 times, resulting in a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 2632.38095238
The remainder is 8 after subtracting 672 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 2632.38095238, with a leftover of 8e-09.
