Let's divide 298230 by 21
Let's see how many times 21 fits into 298230.

Step 1:
21 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 21

Moving on to step 2:
When dividing 29 by 21, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 21 from 29, we get 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 21

Moving on to step 3:
If we divide 88 by 21, we get 4 and a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 4 after subtracting 84 from 88.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 21

Going ahead to step 4:
If we divide 42 by 21, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 142.0
Subtracting 42 from 42 leaves us with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 21

Step 5:
If we divide 3 by 21, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 1420.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 21

Step 6:
21 goes into 30 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 14201.0
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.

Moving on to step 7:
21 can be fit into 90 4 times, resulting in a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 14201.4
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.

Moving on to step 8:
The number 21 fits into 60 2 times, leaving a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 14201.42
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.

Let's proceed to step 9:
180 divided by 21 is 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 14201.428
The remainder is 12 after subtracting 168 from 180.
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.
Write down 5 as next digit of the result. 
Result so far: 14201.4285
If we take 105 away from 120, we end up 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 11:
The number 21 fits into 150 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 14201.42857
If we take 147 away from 150, we end up 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.

Advancing to step 12:
30 divided by 21 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 14201.428571
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.
Put 4 as the next digit of the answer. 
Result so far: 14201.4285714
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.

Advancing to step 14:
If we divide 60 by 21, we get 2 and a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 14201.42857142
Subtracting 42 from 60 leaves us 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.

The final result is 14201.42857142 with a remainder of 1.8e-08.
