We're dividing 298606 by 21 
We want to divide 298606 by 21.

Advancing to step 1:
When dividing 2 by 21, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (9) from the dividend after 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
The remainder is 8 after subtracting 21 from 29.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 21

Moving on to step 3:
The number 21 fits into 88 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we take 84 away from 88, we end up with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 21

Let's proceed to step 4:
The number 21 fits into 46 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 142.0
If we take 42 away from 46, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 21

Step 5:
40 divided by 21 is 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1421.0
Subtracting 21 from 40 leaves us with 19.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 21

Moving on to step 6:
21 goes into 196 9 times with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 14219.0
Subtracting 189 from 196 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
The number 21 fits into 70 3 times, leaving a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 14219.3
The remainder is 7 after subtracting 63 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 8:
The number 21 fits into 70 3 times, leaving a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 14219.33
Subtract 63 from 70 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 14219.33 and a remainder of 0.007.
