Let's divide 21482393 by 664
We want to divide 21482393 by 664.

Step 1:
The number 664 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 664

Moving on to step 2:
When dividing 21 by 664, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 664

Let's proceed to step 3:
664 goes into 214 0 times with a remainder of 214.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 214 leaves us with 214.
Append the next digit (8) from the dividend to 214 and continue with: 2148 / 664

Let's proceed to step 4:
If we divide 2148 by 664, we get 3 and a remainder of 156.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 1992 from 2148 to get 156.
Include the next digit (2) from the dividend after 156, then repeat: 1562 / 664

Going ahead to step 5:
664 can be fit into 1562 2 times, resulting in a remainder of 234.
The next digit of our result is 2. 
Result so far: 32.0
If we take 1328 away from 1562, we end up with 234.
Take the next digit (3) from the dividend and append it to 234, then repeat: 2343 / 664

On to step 6:
The number 664 fits into 2343 3 times, leaving a remainder of 351.
Use 3 as the next digit of our solution. 
Result so far: 323.0
Deduct 1992 from 2343 and we're left with 351.
Append the next digit (9) from the dividend to 351 and continue with: 3519 / 664

Advancing to step 7:
The number 664 fits into 3519 5 times, leaving a remainder of 199.
Write down 5 as next digit of the result. 
Result so far: 3235.0
The remainder is 199 after subtracting 3320 from 3519.
Include the next digit (3) from the dividend after 199, then repeat: 1993 / 664

Let's proceed to step 8:
If we divide 1993 by 664, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 32353.0
Subtract 1992 from 1993 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.

Let's proceed to step 9:
10 divided by 664 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 32353.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
When dividing 100 by 664, we get 0 with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 32353.0
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 32353.0, with a leftover of 0.1.
