998848 divided by 21 
We want to divide 998848 by 21.

Going ahead to step 1:
9 divided by 21 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 21

Step 2:
21 can be fit into 99 4 times, resulting in a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 84 from 99 and we're left with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 21

Going ahead to step 3:
158 divided by 21 is 7 with a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
Subtract 147 from 158 to get 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 21

Going ahead to step 4:
If we divide 118 by 21, we get 5 and a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 475.0
Deduct 105 from 118 and we're left with 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 21

Let's proceed to step 5:
21 can be fit into 134 6 times, resulting in a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 4756.0
If we subtract 126 from 134, we get 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 21

Advancing to step 6:
21 can be fit into 88 4 times, resulting in a remainder of 4.
The next digit of our result is 4. 
Result so far: 47564.0
Subtract 84 from 88 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 47564.1
If we take 21 away from 40, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 8:
190 divided by 21 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 47564.19
Deduct 189 from 190 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
21 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 47564.19
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
When dividing 100 by 21, we get 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 47564.1904
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
21 goes into 160 7 times with a remainder of 13.
The next digit of our result is 7. 
Result so far: 47564.19047
Deduct 147 from 160 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 12:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 47564.190476
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
When dividing 40 by 21, we get 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 47564.1904761
If we take 21 away from 40, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 14:
When dividing 190 by 21, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 47564.19047619
If we take 189 away from 190, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 47564.19047619 and a remainder of 1e-09.
