We divide 334053 by 21
We want to divide 334053 by 21.

Step 1:
21 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 21

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

Let's proceed to step 3:
21 goes into 124 5 times with a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 105 from 124, we get 19.
Take the next digit (0) from the dividend and append it to 19, then repeat: 190 / 21

Step 4:
190 divided by 21 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
The remainder is 1 after subtracting 189 from 190.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 21

Moving on to step 5:
15 divided by 21 is 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 1590.0
The remainder is 15 after subtracting 0 from 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 21

On to step 6:
153 divided by 21 is 7 with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 15907.0
The remainder is 6 after subtracting 147 from 153.
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 7:
When dividing 60 by 21, we get 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 15907.2
If we take 42 away from 60, we end up 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.

Let's proceed to step 8:
21 can be fit into 180 8 times, resulting in a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 15907.28
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 9:
21 goes into 120 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 15907.285
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.

Moving on to step 10:
21 can be fit into 150 7 times, resulting in a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 15907.2857
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.

On to step 11:
30 divided by 21 is 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 15907.28571
If we subtract 21 from 30, 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.

Moving on to step 12:
21 goes into 90 4 times with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 15907.285714
Subtracting 84 from 90 leaves us 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.

Let's proceed to step 13:
21 goes into 60 2 times with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 15907.2857142
Deduct 42 from 60 and we're left 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.

Let's proceed to step 14:
21 can be fit into 180 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 15907.28571428
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.

After the division, we end up with 15907.28571428 and a remainder of 1.2e-08.
