881998 ÷ 21 
Let's see how many times 21 fits into 881998.

Moving on to step 1:
When dividing 8 by 21, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 21

Going ahead to step 2:
If we divide 88 by 21, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 84 from 88 and we're left with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 21

Let's proceed to step 3:
21 goes into 41 1 times with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
If we subtract 21 from 41, we get 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 21

Moving on to step 4:
If we divide 209 by 21, we get 9 and a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 419.0
Subtracting 189 from 209 leaves us with 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 21

Step 5:
When dividing 209 by 21, we get 9 with a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 4199.0
If we take 189 away from 209, we end up with 20.
Bring next digit (8) of the dividend behind the 20 and repeat the process: 208 / 21

On to step 6:
208 divided by 21 is 9 with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 41999.0
Deduct 189 from 208 and we're left 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.

Let's proceed to step 7:
21 goes into 190 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 41999.9
Subtract 189 from 190 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 8:
21 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 41999.9
Subtract 0 from 10 to 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.

Advancing to step 9:
21 goes into 100 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 41999.904
Subtract 84 from 100 to 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.

Moving on to step 10:
If we divide 160 by 21, we get 7 and a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 41999.9047
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 11:
The number 21 fits into 130 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 41999.90476
If we take 126 away from 130, we end up with 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 12:
When dividing 40 by 21, we get 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 41999.904761
Deduct 21 from 40 and we're left 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 13:
The number 21 fits into 190 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 41999.9047619
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 14:
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: 41999.9047619
Subtract 0 from 10 to 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.

After the division, we end up with 41999.9047619 and a remainder of 1e-08.
