884262 ÷ 21 
We want to figure out the number of times 884262 can be divided by 21.

Step 1:
21 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 21

Moving on to step 2:
88 divided by 21 is 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.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 21

Advancing to step 3:
44 divided by 21 is 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Deduct 42 from 44 and we're left with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 21

On to step 4:
When dividing 22 by 21, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 421.0
Deduct 21 from 22 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 21

Advancing to step 5:
21 goes into 16 0 times with a remainder of 16.
The next digit of our result is 0. 
Result so far: 4210.0
Subtract 0 from 16 to get 16.
Include the next digit (2) from the dividend after 16, then repeat: 162 / 21

Moving on to step 6:
When dividing 162 by 21, we get 7 with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 42107.0
If we subtract 147 from 162, we 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.

Moving on to step 7:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 42107.7
The remainder is 3 after subtracting 147 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
21 goes into 30 1 times with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 42107.71
If we subtract 21 from 30, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
90 divided by 21 is 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 42107.714
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.

Step 10:
21 goes into 60 2 times with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 42107.7142
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 11:
The number 21 fits into 180 8 times, leaving a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 42107.71428
If we take 168 away from 180, we end up 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 12:
21 goes into 120 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 42107.714285
Deduct 105 from 120 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 13:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 42107.7142857
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.

Let's proceed to step 14:
The number 21 fits into 30 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 42107.71428571
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.

After the division, we end up with 42107.71428571 and a remainder of 9e-09.
