We're dividing 469039 by 21 
We want to figure out the number of times 469039 can be divided by 21.

Advancing to step 1:
If we divide 4 by 21, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 21

Advancing to step 2:
21 goes into 46 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 42 from 46 and we're left with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 21

Step 3:
The number 21 fits into 49 2 times, leaving a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtracting 42 from 49 leaves us with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 21

Moving on to step 4:
70 divided by 21 is 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 223.0
Subtract 63 from 70 to get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 21

Advancing to step 5:
If we divide 73 by 21, we get 3 and a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 2233.0
Subtracting 63 from 73 leaves us with 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 21

On to step 6:
The number 21 fits into 109 5 times, leaving a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 22335.0
Subtract 105 from 109 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
21 can be fit into 40 1 times, resulting in a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 22335.1
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:
If we divide 190 by 21, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 22335.19
If we subtract 189 from 190, we 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.

Going ahead to 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: 22335.19
If we take 0 away from 10, we end up 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.

On to step 10:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 22335.1904
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
21 goes into 160 7 times with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 22335.19047
Subtracting 147 from 160 leaves us 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.

On to step 12:
21 can be fit into 130 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 22335.190476
If we take 126 away from 130, 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.

Going ahead to step 13:
21 goes into 40 1 times with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 22335.1904761
The remainder is 19 after subtracting 21 from 40.
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:
190 divided by 21 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 22335.19047619
If we subtract 189 from 190, we 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 final result is 22335.19047619 with a remainder of 1e-09.
