We divide 8816963 by 21
We want to figure out the number of times 8816963 can be divided by 21.

On 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.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 21

Moving on to step 2:
When dividing 88 by 21, we get 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 84 from 88 and we're left with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 21

Advancing to step 3:
The number 21 fits into 41 1 times, leaving a remainder of 20.
The next digit of our result is 1. 
Result so far: 41.0
If we take 21 away from 41, we end up with 20.
Bring next digit (6) of the dividend behind the 20 and repeat the process: 206 / 21

Going ahead to step 4:
If we divide 206 by 21, we get 9 and a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 419.0
Subtract 189 from 206 to get 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 21

Moving on to step 5:
21 can be fit into 179 8 times, resulting in a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 4198.0
Subtract 168 from 179 to get 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 21

Let's proceed to step 6:
When dividing 116 by 21, we get 5 with a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 41985.0
If we subtract 105 from 116, we get 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 21

Advancing to step 7:
If we divide 113 by 21, we get 5 and a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 419855.0
Subtract 105 from 113 to get 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 8:
21 can be fit into 80 3 times, resulting in a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 419855.3
If we subtract 63 from 80, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 9:
21 can be fit into 170 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 419855.38
Subtracting 168 from 170 leaves us 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.

On to step 10:
The number 21 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 419855.38
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
200 divided by 21 is 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 419855.3809
If we subtract 189 from 200, we 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.

Going ahead to step 12:
21 goes into 110 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 419855.38095
The remainder is 5 after subtracting 105 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 13:
21 can be fit into 50 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 419855.380952
Subtracting 42 from 50 leaves us 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.

Step 14:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 419855.3809523
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.

Step 15:
If we divide 170 by 21, we get 8 and a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 419855.38095238
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.

The final result is 419855.38095238 with a remainder of 2e-09.
