325608 ÷ 21 
We want to figure out the number of times 325608 can be divided by 21.

On to step 1:
If we divide 3 by 21, we get 0 and a remainder of 3.
The next digit of our result is 0. 
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

On to step 2:
21 can be fit into 32 1 times, resulting in a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 21 from 32 to get 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 21

Advancing to step 3:
The number 21 fits into 115 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 105 away from 115, we end up with 10.
Append the next digit (6) from the dividend to 10 and continue with: 106 / 21

Moving on to step 4:
106 divided by 21 is 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 155.0
Subtracting 105 from 106 leaves us with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 21

Let's proceed to step 5:
If we divide 10 by 21, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1550.0
The remainder is 10 after subtracting 0 from 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 21

Let's proceed to step 6:
If we divide 108 by 21, we get 5 and a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 15505.0
The remainder is 3 after subtracting 105 from 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
21 can be fit into 30 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 15505.1
Subtract 21 from 30 to get 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 8:
90 divided by 21 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 15505.14
Subtracting 84 from 90 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 9:
If we divide 60 by 21, we get 2 and a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 15505.142
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.

Going ahead to step 10:
21 goes into 180 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 15505.1428
Subtracting 168 from 180 leaves us 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.

On to step 11:
The number 21 fits into 120 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 15505.14285
If we subtract 105 from 120, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 12:
When dividing 150 by 21, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 15505.142857
Deduct 147 from 150 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
If we divide 30 by 21, we get 1 and a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 15505.1428571
The remainder is 9 after subtracting 21 from 30.
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 14:
90 divided by 21 is 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 15505.14285714
If we subtract 84 from 90, we 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.

The quotient of the division is 15505.14285714, and the remainder is 6e-09.
