Let's divide 20880396 by 408
We want to figure out the number of times 20880396 can be divided by 408.

Let's proceed to step 1:
408 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 408

Step 2:
408 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Include the next digit (8) from the dividend after 20, then repeat: 208 / 408

Moving on to step 3:
408 can be fit into 208 0 times, resulting in a remainder of 208.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 208, we get 208.
Bring next digit (8) of the dividend behind the 208 and repeat the process: 2088 / 408

Going ahead to step 4:
408 can be fit into 2088 5 times, resulting in a remainder of 48.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 2040 from 2088 leaves us with 48.
Take the next digit (0) from the dividend and append it to 48, then repeat: 480 / 408

Let's proceed to step 5:
408 can be fit into 480 1 times, resulting in a remainder of 72.
The next digit of our result is 1. 
Result so far: 51.0
Deduct 408 from 480 and we're left with 72.
Grab the next digit (3) from the dividend, add it to 72, then carry on: 723 / 408

On to step 6:
408 goes into 723 1 times with a remainder of 315.
The number 1 becomes the next digit in our result. 
Result so far: 511.0
If we take 408 away from 723, we end up with 315.
Grab the next digit (9) from the dividend, add it to 315, then carry on: 3159 / 408

Let's proceed to step 7:
408 goes into 3159 7 times with a remainder of 303.
Put 7 as the next digit of the answer. 
Result so far: 5117.0
If we take 2856 away from 3159, we end up with 303.
Append the next digit (6) from the dividend to 303 and continue with: 3036 / 408

Going ahead to step 8:
If we divide 3036 by 408, we get 7 and a remainder of 180.
Use 7 as the next digit of our solution. 
Result so far: 51177.0
If we subtract 2856 from 3036, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 9:
The number 408 fits into 1800 4 times, leaving a remainder of 168.
Use 4 as the next digit of our solution. 
Result so far: 51177.4
Subtracting 1632 from 1800 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 10:
When dividing 1680 by 408, we get 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 51177.44
Deduct 1632 from 1680 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

In conclusion, the division gives 51177.44 with a balance of 0.048.
