884662 ÷ 21 
We want to figure out the number of times 884662 can be divided by 21.

Step 1:
The number 21 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 21

Step 2:
21 can be fit into 88 4 times, resulting in a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 4 after subtracting 84 from 88.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 21

On to step 3:
When dividing 44 by 21, we get 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtract 42 from 44 to get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 21

On to step 4:
If we divide 26 by 21, we get 1 and a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 421.0
The remainder is 5 after subtracting 21 from 26.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 21

On to step 5:
56 divided by 21 is 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 4212.0
If we subtract 42 from 56, we get 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 21

Step 6:
The number 21 fits into 142 6 times, leaving a remainder of 16.
The next digit of our result is 6. 
Result so far: 42126.0
If we take 126 away from 142, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
If we divide 160 by 21, we get 7 and a remainder of 13.
The next digit of our result is 7. 
Result so far: 42126.7
If we take 147 away from 160, we end up 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.

Advancing to step 8:
130 divided by 21 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 42126.76
Deduct 126 from 130 and we're left 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.

Moving on to step 9:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 42126.761
Subtract 21 from 40 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 10:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 42126.7619
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.

On to step 11:
10 divided by 21 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 42126.7619
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
100 divided by 21 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 42126.761904
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
If we divide 160 by 21, we get 7 and a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 42126.7619047
Subtracting 147 from 160 leaves us 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.

Going ahead to step 14:
If we divide 130 by 21, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 42126.76190476
Deduct 126 from 130 and we're left 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.

In conclusion, the division gives 42126.76190476 with a balance of 4e-09.
