326722 divided by 21 
We're looking to find how many times 21 goes into 326722.

Advancing to step 1:
21 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 21

On to step 2:
The number 21 fits into 32 1 times, leaving a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 21 from 32 and we're left with 11.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 21

Let's proceed to step 3:
When dividing 116 by 21, we get 5 with a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 105 from 116 leaves us with 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 21

Step 4:
When dividing 117 by 21, we get 5 with a remainder of 12.
The next digit of our result is 5. 
Result so far: 155.0
The remainder is 12 after subtracting 105 from 117.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 21

Going ahead to step 5:
21 can be fit into 122 5 times, resulting in a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 1555.0
If we take 105 away from 122, we end up with 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 21

Let's proceed to step 6:
When dividing 172 by 21, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 15558.0
Subtracting 168 from 172 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.

Moving on to step 7:
If we divide 40 by 21, we get 1 and a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 15558.1
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.

On to step 8:
21 can be fit into 190 9 times, resulting in a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 15558.19
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.

Moving on to step 9:
The number 21 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 15558.19
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
21 goes into 100 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 15558.1904
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
If we divide 160 by 21, we get 7 and a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 15558.19047
If we subtract 147 from 160, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 12:
130 divided by 21 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 15558.190476
Subtract 126 from 130 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.

On to step 13:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 15558.1904761
Subtracting 21 from 40 leaves us 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 14:
190 divided by 21 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 15558.19047619
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 15558.19047619 with a balance of 1e-09.
