We're dividing 444299 by 21 
We're looking to find how many times 21 goes into 444299.

Advancing to step 1:
4 divided by 21 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 21

Advancing to step 2:
The number 21 fits into 44 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 2 after subtracting 42 from 44.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 21

Advancing to step 3:
If we divide 24 by 21, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtract 21 from 24 to get 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 21

Going ahead to step 4:
21 can be fit into 32 1 times, resulting in a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 211.0
Subtract 21 from 32 to get 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 21

Going ahead to step 5:
119 divided by 21 is 5 with a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 2115.0
The remainder is 14 after subtracting 105 from 119.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 21

Going ahead to step 6:
21 can be fit into 149 7 times, resulting in a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 21157.0
If we take 147 away from 149, 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.

Advancing to step 7:
21 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 21157.0
If we subtract 0 from 20, we 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.

Moving on to step 8:
The number 21 fits into 200 9 times, leaving a remainder of 11.
The next digit of our result is 9. 
Result so far: 21157.09
Subtract 189 from 200 to get 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 9:
When dividing 110 by 21, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 21157.095
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 10:
50 divided by 21 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 21157.0952
Deduct 42 from 50 and we're left 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 11:
80 divided by 21 is 3 with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 21157.09523
Subtracting 63 from 80 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 12:
When dividing 170 by 21, we get 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 21157.095238
Deduct 168 from 170 and we're left 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.

Moving on to step 13:
The number 21 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 21157.095238
If we subtract 0 from 20, we 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.

On to step 14:
21 goes into 200 9 times with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 21157.09523809
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.

The final result is 21157.09523809 with a remainder of 1.1e-08.
