21895724 ÷ 84 
Our goal is to divide 21895724 by 84.

Let's proceed to step 1:
2 divided by 84 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 84

Moving on to step 2:
84 can be fit into 21 0 times, resulting in a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 84

Let's proceed to step 3:
The number 84 fits into 218 2 times, leaving a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 168 away from 218, we end up with 50.
Fetch the next digit (9) from the dividend, attach it to 50 and continue: 509 / 84

On to step 4:
509 divided by 84 is 6 with a remainder of 5.
The next digit of our result is 6. 
Result so far: 26.0
Deduct 504 from 509 and we're left with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 84

Moving on to step 5:
The number 84 fits into 55 0 times, leaving a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 260.0
Subtract 0 from 55 to get 55.
Take the next digit (7) from the dividend and append it to 55, then repeat: 557 / 84

Going ahead to step 6:
557 divided by 84 is 6 with a remainder of 53.
Record the quotient 6 as the next digit in the result. 
Result so far: 2606.0
Subtracting 504 from 557 leaves us with 53.
Grab the next digit (2) from the dividend, add it to 53, then carry on: 532 / 84

On to step 7:
84 can be fit into 532 6 times, resulting in a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 26066.0
Subtract 504 from 532 to get 28.
Include the next digit (4) from the dividend after 28, then repeat: 284 / 84

Advancing to step 8:
84 goes into 284 3 times with a remainder of 32.
Use 3 as the next digit of our solution. 
Result so far: 260663.0
If we take 252 away from 284, we end up 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.

Let's proceed to step 9:
320 divided by 84 is 3 with a remainder of 68.
The next digit of our result is 3. 
Result so far: 260663.3
If we take 252 away from 320, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 10:
680 divided by 84 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 260663.38
Subtracting 672 from 680 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
If we divide 80 by 84, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 260663.38
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
84 goes into 800 9 times with a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 260663.3809
Subtract 756 from 800 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 13:
440 divided by 84 is 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 260663.38095
The remainder is 20 after subtracting 420 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 14:
84 can be fit into 200 2 times, resulting in a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 260663.380952
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.

On to step 15:
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: 260663.3809523
Subtract 252 from 320 to 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.

Advancing to step 16:
The number 84 fits into 680 8 times, leaving a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 260663.38095238
Subtract 672 from 680 to 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.

The final result is 260663.38095238 with a remainder of 8e-09.
