We're dividing 881240 by 21 
Our goal is to divide 881240 by 21.

Advancing to step 1:
21 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 21

Let's proceed to step 2:
88 divided by 21 is 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 4.0
If we take 84 away from 88, we end up with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 21

Let's proceed to step 3:
21 goes into 41 1 times with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
The remainder is 20 after subtracting 21 from 41.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 21

Going ahead to step 4:
If we divide 202 by 21, we get 9 and a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 419.0
Subtracting 189 from 202 leaves us with 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 21

Moving on to step 5:
21 can be fit into 134 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 4196.0
Subtract 126 from 134 to get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 21

On to step 6:
When dividing 80 by 21, we get 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 41963.0
Deduct 63 from 80 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
21 goes into 170 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 41963.8
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.

Moving on to step 8:
21 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 41963.8
If we take 0 away from 20, we end up 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.

Advancing to step 9:
21 goes into 200 9 times with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 41963.809
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.

Step 10:
If we divide 110 by 21, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 41963.8095
Deduct 105 from 110 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
21 goes into 50 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 41963.80952
Deduct 42 from 50 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
21 can be fit into 80 3 times, resulting in a remainder of 17.
The next digit of our result is 3. 
Result so far: 41963.809523
Subtracting 63 from 80 leaves us with 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 13:
21 goes into 170 8 times with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 41963.8095238
Subtract 168 from 170 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 14:
21 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 41963.8095238
If we take 0 away from 20, we end up 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.

After the division, we end up with 41963.8095238 and a remainder of 2e-08.
