325514 ÷ 21 
We're looking to find how many times 21 goes into 325514.

Advancing to step 1:
3 divided by 21 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 21

Advancing to step 2:
When dividing 32 by 21, we get 1 with 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.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 21

On to step 3:
The number 21 fits into 115 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 105 from 115 to get 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 21

Moving on to step 4:
105 divided by 21 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 155.0
If we take 105 away from 105, we end up with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 21

Moving on to step 5:
The number 21 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 1550.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 21

On to step 6:
21 can be fit into 14 0 times, resulting in a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 15500.0
If we take 0 away from 14, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
21 can be fit into 140 6 times, resulting in a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 15500.6
Subtract 126 from 140 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
When dividing 140 by 21, we get 6 with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 15500.66
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 15500.66, and the remainder is 0.014.
