Let's divide 322608 by 21
We want to figure out the number of times 322608 can be divided by 21.

Let's proceed to step 1:
The number 21 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
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:
21 goes into 32 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 21 from 32 leaves us with 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 21

On to step 3:
21 can be fit into 112 5 times, resulting in a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 105 from 112 leaves us with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 21

On to step 4:
21 goes into 76 3 times with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 153.0
Subtracting 63 from 76 leaves us with 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 21

Advancing to step 5:
The number 21 fits into 130 6 times, leaving a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 1536.0
If we take 126 away from 130, we end up with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 21

Advancing to step 6:
48 divided by 21 is 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 15362.0
Subtracting 42 from 48 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
21 goes into 60 2 times with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 15362.2
Subtracting 42 from 60 leaves us 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.

Moving on to step 8:
21 can be fit into 180 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 15362.28
If we take 168 away from 180, we end up 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.

Step 9:
21 goes into 120 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 15362.285
Deduct 105 from 120 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
When dividing 150 by 21, we get 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 15362.2857
The remainder is 3 after subtracting 147 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 11:
When dividing 30 by 21, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 15362.28571
If we take 21 away from 30, we end up 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.

On to step 12:
The number 21 fits into 90 4 times, leaving a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 15362.285714
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.

On to step 13:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 15362.2857142
Subtract 42 from 60 to 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.

Step 14:
The number 21 fits into 180 8 times, leaving a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 15362.28571428
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 15362.28571428 and a remainder of 1.2e-08.
