444708 ÷ 21 
Let's see how many times 21 fits into 444708.

Advancing to step 1:
If we divide 4 by 21, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 21

Step 2:
21 goes into 44 2 times with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 42 away from 44, we end up with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 21

Going ahead to step 3:
21 goes into 24 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtracting 21 from 24 leaves us with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 21

On to step 4:
When dividing 37 by 21, we get 1 with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 211.0
If we subtract 21 from 37, we get 16.
Append the next digit (0) from the dividend to 16 and continue with: 160 / 21

Step 5:
160 divided by 21 is 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 2117.0
Subtracting 147 from 160 leaves us with 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 21

Going ahead to step 6:
If we divide 138 by 21, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 21176.0
If we take 126 away from 138, 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.

Going ahead to step 7:
If we divide 120 by 21, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 21176.5
If we take 105 away from 120, we end up 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.

On to step 8:
If we divide 150 by 21, we get 7 and a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 21176.57
Deduct 147 from 150 and we're left with 3.
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 9:
When dividing 30 by 21, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 21176.571
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.

Let's proceed to step 10:
21 goes into 90 4 times with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 21176.5714
Deduct 84 from 90 and we're left 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 11:
The number 21 fits into 60 2 times, leaving a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 21176.57142
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 12:
21 goes into 180 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 21176.571428
Subtracting 168 from 180 leaves us 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.

Let's proceed to step 13:
21 goes into 120 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 21176.5714285
Subtract 105 from 120 to 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.

Advancing to step 14:
21 can be fit into 150 7 times, resulting in a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 21176.57142857
Deduct 147 from 150 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 21176.57142857 with a remainder of 3e-09.
