898808 ÷ 21 
We want to divide 898808 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
If we take 0 away from 8, we end up with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 21

On to step 2:
If we divide 89 by 21, we get 4 and a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 84 away from 89, we end up with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 21

Going ahead to step 3:
21 goes into 58 2 times with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Subtract 42 from 58 to get 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 21

On to step 4:
21 goes into 168 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 428.0
The remainder is 0 after subtracting 168 from 168.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 21

Going ahead to step 5:
When dividing 0 by 21, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4280.0
If we subtract 0 from 0, we get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 21

Going ahead to step 6:
21 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 42800.0
The remainder is 8 after subtracting 0 from 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
The number 21 fits into 80 3 times, leaving a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 42800.3
Subtract 63 from 80 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 8:
21 goes into 170 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 42800.38
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
21 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 42800.38
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
200 divided by 21 is 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 42800.3809
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 11:
110 divided by 21 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 42800.38095
Subtract 105 from 110 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 12:
50 divided by 21 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 42800.380952
If we subtract 42 from 50, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
When dividing 80 by 21, we get 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 42800.3809523
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 14:
If we divide 170 by 21, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 42800.38095238
If we take 168 away from 170, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 42800.38095238 and a remainder of 2e-09.
