Let's divide 447246 by 21
Let's see how many times 21 fits into 447246.

Moving on 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
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

Step 2:
When dividing 44 by 21, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 42 from 44, we get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 21

Moving on to step 3:
27 divided by 21 is 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtract 21 from 27 to get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 21

On to step 4:
62 divided by 21 is 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 212.0
If we take 42 away from 62, we end up with 20.
Fetch the next digit (4) from the dividend, attach it to 20 and continue: 204 / 21

Let's proceed to step 5:
The number 21 fits into 204 9 times, leaving a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 2129.0
If we subtract 189 from 204, we get 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 21

Moving on to step 6:
21 goes into 156 7 times with a remainder of 9.
The next digit of our result is 7. 
Result so far: 21297.0
If we subtract 147 from 156, 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 7:
When dividing 90 by 21, we get 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 21297.4
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
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: 21297.42
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
180 divided by 21 is 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 21297.428
Deduct 168 from 180 and we're left 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 10:
120 divided by 21 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 21297.4285
If we subtract 105 from 120, 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.

Let's proceed to step 11:
21 can be fit into 150 7 times, resulting in a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 21297.42857
If we subtract 147 from 150, we 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.

Advancing to step 12:
21 goes into 30 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 21297.428571
Subtracting 21 from 30 leaves us 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.

Moving on to step 13:
21 can be fit into 90 4 times, resulting in a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 21297.4285714
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 14:
When dividing 60 by 21, we get 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 21297.42857142
If we subtract 42 from 60, we 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.

The final outcome is 21297.42857142, with a leftover of 1.8e-08.
