We look at the division of 883704 by 21 
We want to divide 883704 by 21.

Going ahead to step 1:
8 divided by 21 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 21

Moving on to step 2:
21 can be fit into 88 4 times, resulting in a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 84 from 88 to get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 21

Let's proceed to step 3:
43 divided by 21 is 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
If we subtract 42 from 43, we get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 21

Going ahead to step 4:
The number 21 fits into 17 0 times, leaving a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 420.0
Subtract 0 from 17 to get 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 21

On to step 5:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 4208.0
If we subtract 168 from 170, we get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 21

Let's proceed to step 6:
24 divided by 21 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 42081.0
If we subtract 21 from 24, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
21 goes into 30 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 42081.1
Subtracting 21 from 30 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 8:
21 can be fit into 90 4 times, resulting in a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 42081.14
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
If we divide 60 by 21, we get 2 and a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 42081.142
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
21 goes into 180 8 times with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 42081.1428
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
120 divided by 21 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 42081.14285
Subtract 105 from 120 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 12:
150 divided by 21 is 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 42081.142857
Subtract 147 from 150 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
The number 21 fits into 30 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 42081.1428571
If we take 21 away from 30, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 14:
When dividing 90 by 21, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 42081.14285714
Subtracting 84 from 90 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 42081.14285714, and the remainder is 6e-09.
