We look at the division of 322489 by 21 
We want to figure out the number of times 322489 can be divided by 21.

Advancing to step 1:
If we divide 3 by 21, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 21

Going ahead to step 2:
When dividing 32 by 21, we get 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 21 away from 32, we end up with 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 21

Let's proceed to step 3:
21 can be fit into 112 5 times, resulting in a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 105 from 112 and we're left with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 21

Advancing to step 4:
The number 21 fits into 74 3 times, leaving a remainder of 11.
The next digit of our result is 3. 
Result so far: 153.0
The remainder is 11 after subtracting 63 from 74.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 21

Going ahead to step 5:
21 goes into 118 5 times with a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 1535.0
Subtract 105 from 118 to get 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 21

Let's proceed to step 6:
139 divided by 21 is 6 with a remainder of 13.
Write down 6 as next digit of the result. 
Result so far: 15356.0
The remainder is 13 after subtracting 126 from 139.
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 7:
130 divided by 21 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 15356.6
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 15356.61
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.

Step 9:
When dividing 190 by 21, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 15356.619
Deduct 189 from 190 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 10:
21 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 15356.619
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 11:
If we divide 100 by 21, we get 4 and a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 15356.61904
If we take 84 away from 100, we end up 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.

Advancing to step 12:
If we divide 160 by 21, we get 7 and a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 15356.619047
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 13:
130 divided by 21 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 15356.6190476
Subtracting 126 from 130 leaves us 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.

Advancing to step 14:
40 divided by 21 is 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 15356.61904761
Subtract 21 from 40 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 15356.61904761, with a leftover of 1.9e-08.
