447031 divided by 21 
Our goal is to divide 447031 by 21.

On to step 1:
21 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 21

Advancing to step 2:
If we divide 44 by 21, we get 2 and 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.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 21

Let's proceed to step 3:
If we divide 27 by 21, we get 1 and a remainder of 6.
The next digit of our result is 1. 
Result so far: 21.0
Subtract 21 from 27 to get 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 21

Let's proceed to step 4:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 212.0
If we take 42 away from 60, we end up with 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 21

Let's proceed to step 5:
21 goes into 183 8 times with a remainder of 15.
The next digit of our result is 8. 
Result so far: 2128.0
The remainder is 15 after subtracting 168 from 183.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 21

Step 6:
21 can be fit into 151 7 times, resulting in a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 21287.0
If we take 147 away from 151, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
When dividing 40 by 21, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 21287.1
If we take 21 away from 40, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 8:
21 can be fit into 190 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 21287.19
Subtract 189 from 190 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
If we divide 10 by 21, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 21287.19
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
21 goes into 100 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 21287.1904
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
When dividing 160 by 21, we get 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 21287.19047
If we take 147 away from 160, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 12:
130 divided by 21 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 21287.190476
Deduct 126 from 130 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 21287.1904761
If we take 21 away from 40, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 14:
21 can be fit into 190 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 21287.19047619
Subtract 189 from 190 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 21287.19047619, and the remainder is 1e-09.
