298340 divided by 21 
We're looking to find how many times 21 goes into 298340.

Advancing to step 1:
When dividing 2 by 21, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 21

Let's proceed to step 2:
When dividing 29 by 21, we get 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 21 away from 29, we end up with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 21

Going ahead to step 3:
21 goes into 88 4 times with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we subtract 84 from 88, we get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 21

Going ahead to step 4:
21 can be fit into 43 2 times, resulting in a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 142.0
If we take 42 away from 43, we end up with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 21

Step 5:
14 divided by 21 is 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 1420.0
Subtracting 0 from 14 leaves us with 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 21

Let's proceed to step 6:
If we divide 140 by 21, we get 6 and a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 14206.0
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
140 divided by 21 is 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 14206.6
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
140 divided by 21 is 6 with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 14206.66
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 14206.66 and a remainder of 0.014.
