334035 divided by 21 
We're looking to find how many times 21 goes into 334035.

On to step 1:
3 divided by 21 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 21

Moving on to step 2:
21 can be fit into 33 1 times, resulting in a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 21 from 33 and we're left with 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 21

Let's proceed to step 3:
When dividing 124 by 21, we get 5 with a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 105 from 124 to get 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 21

Moving on to step 4:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 159.0
Subtracting 189 from 190 leaves us with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 21

On to step 5:
If we divide 13 by 21, we get 0 and a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 1590.0
Subtract 0 from 13 to get 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 21

Moving on to step 6:
135 divided by 21 is 6 with a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 15906.0
If we subtract 126 from 135, we get 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:
The number 21 fits into 90 4 times, leaving a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 15906.4
The remainder is 6 after subtracting 84 from 90.
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 8:
When dividing 60 by 21, we get 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 15906.42
Subtract 42 from 60 to 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 9:
21 goes into 180 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 15906.428
Subtracting 168 from 180 leaves us 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.

Step 10:
21 can be fit into 120 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 15906.4285
Subtracting 105 from 120 leaves us 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.

Going ahead to step 11:
21 can be fit into 150 7 times, resulting in a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 15906.42857
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:
21 goes into 30 1 times with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 15906.428571
Subtracting 21 from 30 leaves us 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.

Going ahead to step 13:
The number 21 fits into 90 4 times, leaving a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 15906.4285714
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.

Let's proceed to step 14:
When dividing 60 by 21, we get 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 15906.42857142
Subtract 42 from 60 to 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.

In conclusion, the division gives 15906.42857142 with a balance of 1.8e-08.
