442316 divided by 21 
Let's see how many times 21 fits into 442316.

Moving on to step 1:
If we divide 4 by 21, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 21

Moving on to step 2:
When dividing 44 by 21, we get 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 42 from 44, we get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 21

Moving on to step 3:
When dividing 22 by 21, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
The remainder is 1 after subtracting 21 from 22.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 21

Let's proceed to step 4:
The number 21 fits into 13 0 times, leaving a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 210.0
If we subtract 0 from 13, we get 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 21

On to step 5:
If we divide 131 by 21, we get 6 and a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 2106.0
If we subtract 126 from 131, we get 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 21

Advancing to step 6:
21 goes into 56 2 times with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 21062.0
Subtract 42 from 56 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
21 goes into 140 6 times with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 21062.6
Subtracting 126 from 140 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
If we divide 140 by 21, we get 6 and a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 21062.66
Subtract 126 from 140 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 21062.66 and a remainder of 0.014.
