We're dividing 898218 by 21 
Our goal is to divide 898218 by 21.

Going ahead to step 1:
21 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 21

On to step 2:
21 can be fit into 89 4 times, resulting in a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 5 after subtracting 84 from 89.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 21

On to step 3:
58 divided by 21 is 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
The remainder is 16 after subtracting 42 from 58.
Bring next digit (2) of the dividend behind the 16 and repeat the process: 162 / 21

Advancing to step 4:
If we divide 162 by 21, we get 7 and a remainder of 15.
The next digit of our result is 7. 
Result so far: 427.0
Subtracting 147 from 162 leaves us with 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 21

Step 5:
21 can be fit into 151 7 times, resulting in a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 4277.0
Subtracting 147 from 151 leaves us with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 21

Step 6:
When dividing 48 by 21, we get 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 42772.0
Deduct 42 from 48 and we're left 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.

Going ahead to step 7:
21 goes into 60 2 times with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 42772.2
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.

Step 8:
When dividing 180 by 21, we get 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 42772.28
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.

Let's proceed to step 9:
21 goes into 120 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 42772.285
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.

Step 10:
150 divided by 21 is 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 42772.2857
The remainder is 3 after subtracting 147 from 150.
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 11:
21 goes into 30 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 42772.28571
The remainder is 9 after subtracting 21 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 12:
21 can be fit into 90 4 times, resulting in a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 42772.285714
Deduct 84 from 90 and we're left 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 can be fit into 60 2 times, resulting in a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 42772.2857142
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.

Advancing to step 14:
When dividing 180 by 21, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 42772.28571428
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.

The final outcome is 42772.28571428, with a leftover of 1.2e-08.
