We look at the division of 21411348 by 664 
We want to divide 21411348 by 664.

Step 1:
664 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 664

Advancing to step 2:
The number 664 fits into 21 0 times, leaving a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 664

Going ahead to step 3:
When dividing 214 by 664, we get 0 with a remainder of 214.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 214 to get 214.
Fetch the next digit (1) from the dividend, attach it to 214 and continue: 2141 / 664

Advancing to step 4:
664 goes into 2141 3 times with a remainder of 149.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 149 after subtracting 1992 from 2141.
Fetch the next digit (1) from the dividend, attach it to 149 and continue: 1491 / 664

Step 5:
The number 664 fits into 1491 2 times, leaving a remainder of 163.
The next digit of our result is 2. 
Result so far: 32.0
If we take 1328 away from 1491, we end up with 163.
Include the next digit (3) from the dividend after 163, then repeat: 1633 / 664

Step 6:
When dividing 1633 by 664, we get 2 with a remainder of 305.
The next digit of our result is 2. 
Result so far: 322.0
The remainder is 305 after subtracting 1328 from 1633.
Take the next digit (4) from the dividend and append it to 305, then repeat: 3054 / 664

Let's proceed to step 7:
The number 664 fits into 3054 4 times, leaving a remainder of 398.
Record the quotient 4 as the next digit in the result. 
Result so far: 3224.0
Deduct 2656 from 3054 and we're left with 398.
Take the next digit (8) from the dividend and append it to 398, then repeat: 3988 / 664

On to step 8:
664 can be fit into 3988 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 32246.0
If we subtract 3984 from 3988, we 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.

Let's proceed to step 9:
664 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 32246.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
If we divide 400 by 664, we get 0 and a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 32246.0
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The quotient of the division is 32246.0, and the remainder is 0.4.
