We divide 100898 by 21
Our goal is to divide 100898 by 21.

Moving on to step 1:
1 divided by 21 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 21

On to step 2:
When dividing 10 by 21, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 21

Moving on to step 3:
The number 21 fits into 100 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 84 from 100 and we're left with 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 21

On to step 4:
When dividing 168 by 21, we get 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Deduct 168 from 168 and we're left with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 21

Let's proceed to step 5:
21 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 480.0
If we take 0 away from 9, we end up with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 21

Advancing to step 6:
21 can be fit into 98 4 times, resulting in a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 4804.0
The remainder is 14 after subtracting 84 from 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
When dividing 140 by 21, we get 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 4804.6
Subtract 126 from 140 to 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.

Moving on to step 8:
If we divide 140 by 21, we get 6 and a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 4804.66
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 4804.66 and a remainder of 0.014.
