We look at the division of 334883 by 21 
We want to divide 334883 by 21.

Step 1:
The number 21 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 21

Let's proceed to step 2:
21 goes into 33 1 times with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 12 after subtracting 21 from 33.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 21

On to step 3:
If we divide 124 by 21, we get 5 and a remainder of 19.
The next digit of our result is 5. 
Result so far: 15.0
If we take 105 away from 124, we end up with 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 21

On to step 4:
If we divide 198 by 21, we get 9 and a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 159.0
The remainder is 9 after subtracting 189 from 198.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 21

Going ahead to step 5:
If we divide 98 by 21, we get 4 and a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 1594.0
Subtracting 84 from 98 leaves us with 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 21

Step 6:
21 can be fit into 143 6 times, resulting in a remainder of 17.
Record the quotient 6 as the next digit in the result. 
Result so far: 15946.0
If we take 126 away from 143, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
21 goes into 170 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 15946.8
Subtract 168 from 170 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
21 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 15946.8
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
When dividing 200 by 21, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 15946.809
If we take 189 away from 200, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 10:
The number 21 fits into 110 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 15946.8095
The remainder is 5 after subtracting 105 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
21 goes into 50 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 15946.80952
Subtracting 42 from 50 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.

On to step 12:
80 divided by 21 is 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 15946.809523
Deduct 63 from 80 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 13:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 15946.8095238
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 14:
When dividing 20 by 21, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 15946.8095238
Deduct 0 from 20 and we're left 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.

The final result is 15946.8095238 with a remainder of 2e-08.
