We look at the division of 442184 by 21 
We want to figure out the number of times 442184 can be divided by 21.

Going ahead to step 1:
When dividing 4 by 21, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 21

Moving on to step 2:
44 divided by 21 is 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 42 away from 44, we end up with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 21

Moving on to step 3:
If we divide 22 by 21, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 1 after subtracting 21 from 22.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 21

On to step 4:
When dividing 11 by 21, we get 0 with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 210.0
If we take 0 away from 11, we end up with 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 21

Advancing to step 5:
When dividing 118 by 21, we get 5 with a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 2105.0
If we subtract 105 from 118, we get 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 21

Moving on to step 6:
The number 21 fits into 134 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 21056.0
If we take 126 away from 134, we end up 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.

On to step 7:
80 divided by 21 is 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 21056.3
Subtract 63 from 80 to 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.

Step 8:
170 divided by 21 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 21056.38
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.

Advancing to step 9:
21 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 21056.38
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.

Advancing to step 10:
When dividing 200 by 21, we get 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 21056.3809
If we take 189 away from 200, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 11:
The number 21 fits into 110 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 21056.38095
Subtracting 105 from 110 leaves us 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.

Step 12:
21 goes into 50 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 21056.380952
The remainder is 8 after subtracting 42 from 50.
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 13:
80 divided by 21 is 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 21056.3809523
Subtract 63 from 80 to 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.

Going ahead to step 14:
When dividing 170 by 21, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 21056.38095238
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.

The quotient of the division is 21056.38095238, and the remainder is 2e-09.
