We divide 865281 by 21
We want to divide 865281 by 21.

Going ahead to step 1:
21 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 21

Advancing to step 2:
21 can be fit into 86 4 times, resulting in a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 84 away from 86, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 21

Moving on to step 3:
21 goes into 25 1 times with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
If we take 21 away from 25, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 21

Let's proceed to step 4:
21 goes into 42 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 412.0
Deduct 42 from 42 and we're left with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 21

Let's proceed to step 5:
The number 21 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 4120.0
Subtract 0 from 8 to get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 21

Advancing to step 6:
21 can be fit into 81 3 times, resulting in a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 41203.0
If we subtract 63 from 81, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
21 can be fit into 180 8 times, resulting in a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 41203.8
Deduct 168 from 180 and we're left with 12.
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 8:
21 can be fit into 120 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 41203.85
Deduct 105 from 120 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
If we divide 150 by 21, we get 7 and a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 41203.857
Deduct 147 from 150 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 10:
The number 21 fits into 30 1 times, leaving a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 41203.8571
If we take 21 away from 30, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 11:
If we divide 90 by 21, we get 4 and a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 41203.85714
Deduct 84 from 90 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 12:
60 divided by 21 is 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 41203.857142
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 13:
The number 21 fits into 180 8 times, leaving a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 41203.8571428
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 14:
120 divided by 21 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 41203.85714285
If we subtract 105 from 120, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 41203.85714285 and a remainder of 1.5e-08.
