29865 divided by 21 
Let's see how many times 21 fits into 29865.

Moving on to step 1:
The number 21 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 21

Let's proceed to step 2:
21 goes into 29 1 times with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 21 from 29 and we're left with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 21

On to step 3:
21 goes into 88 4 times with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 84 from 88 to get 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 21

Let's proceed to step 4:
21 can be fit into 46 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 142.0
Subtract 42 from 46 to get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 21

On to step 5:
If we divide 45 by 21, we get 2 and a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 1422.0
If we subtract 42 from 45, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 6:
30 divided by 21 is 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1422.1
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 7:
When dividing 90 by 21, we get 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 1422.14
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
60 divided by 21 is 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 1422.142
If we subtract 42 from 60, 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.

On to step 9:
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: 1422.1428
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 10:
120 divided by 21 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 1422.14285
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.

Let's proceed to step 11:
When dividing 150 by 21, we get 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 1422.142857
If we subtract 147 from 150, we get 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 12:
If we divide 30 by 21, we get 1 and a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1422.1428571
Deduct 21 from 30 and we're left 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.

Step 13:
21 can be fit into 90 4 times, resulting in a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 1422.14285714
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 1422.14285714 and a remainder of 6e-09.
