We divide 20404 by 84
We want to divide 20404 by 84.

Going ahead to step 1:
The number 84 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 84

Let's proceed to step 2:
If we divide 20 by 84, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 84

Moving on to step 3:
204 divided by 84 is 2 with a remainder of 36.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 168 from 204 and we're left with 36.
Fetch the next digit (0) from the dividend, attach it to 36 and continue: 360 / 84

Advancing to step 4:
84 goes into 360 4 times with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 24.0
The remainder is 24 after subtracting 336 from 360.
Fetch the next digit (4) from the dividend, attach it to 24 and continue: 244 / 84

Advancing to step 5:
If we divide 244 by 84, we get 2 and a remainder of 76.
Use 2 as the next digit of our solution. 
Result so far: 242.0
Deduct 168 from 244 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 6:
The number 84 fits into 760 9 times, leaving a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 242.9
Subtract 756 from 760 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
40 divided by 84 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 242.9
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
400 divided by 84 is 4 with a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 242.904
If we subtract 336 from 400, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 9:
When dividing 640 by 84, we get 7 with a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 242.9047
If we take 588 away from 640, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
The number 84 fits into 520 6 times, leaving a remainder of 16.
The next digit of our result is 6. 
Result so far: 242.90476
Subtract 504 from 520 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
When dividing 160 by 84, we get 1 with a remainder of 76.
Put 1 as the next digit of the answer. 
Result so far: 242.904761
If we subtract 84 from 160, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 12:
84 goes into 760 9 times with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 242.9047619
Deduct 756 from 760 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
40 divided by 84 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 242.9047619
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 242.9047619, with a leftover of 4e-08.
