We're dividing 56823639 by 449 
We want to figure out the number of times 56823639 can be divided by 449.

Going ahead to step 1:
When dividing 5 by 449, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 449

Step 2:
449 can be fit into 56 0 times, resulting in a remainder of 56.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 56, we get 56.
Take the next digit (8) from the dividend and append it to 56, then repeat: 568 / 449

Going ahead to step 3:
568 divided by 449 is 1 with a remainder of 119.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 449 from 568 leaves us with 119.
Bring next digit (2) of the dividend behind the 119 and repeat the process: 1192 / 449

Going ahead to step 4:
If we divide 1192 by 449, we get 2 and a remainder of 294.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 898 from 1192 to get 294.
Append the next digit (3) from the dividend to 294 and continue with: 2943 / 449

Step 5:
449 can be fit into 2943 6 times, resulting in a remainder of 249.
Write down 6 as next digit of the result. 
Result so far: 126.0
The remainder is 249 after subtracting 2694 from 2943.
Include the next digit (6) from the dividend after 249, then repeat: 2496 / 449

Let's proceed to step 6:
2496 divided by 449 is 5 with a remainder of 251.
Use 5 as the next digit of our solution. 
Result so far: 1265.0
If we subtract 2245 from 2496, we get 251.
Include the next digit (3) from the dividend after 251, then repeat: 2513 / 449

Going ahead to step 7:
If we divide 2513 by 449, we get 5 and a remainder of 268.
The next digit of our result is 5. 
Result so far: 12655.0
Subtract 2245 from 2513 to get 268.
Include the next digit (9) from the dividend after 268, then repeat: 2689 / 449

Step 8:
If we divide 2689 by 449, we get 5 and a remainder of 444.
Put 5 as the next digit of the answer. 
Result so far: 126555.0
Deduct 2245 from 2689 and we're left with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Let's proceed to step 9:
If we divide 4440 by 449, we get 9 and a remainder of 399.
Put 9 as the next digit of the answer. 
Result so far: 126555.9
Subtracting 4041 from 4440 leaves us with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

On to step 10:
449 goes into 3990 8 times with a remainder of 398.
Record the quotient 8 as the next digit in the result. 
Result so far: 126555.98
Deduct 3592 from 3990 and we're left with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Advancing to step 11:
The number 449 fits into 3980 8 times, leaving a remainder of 388.
Use 8 as the next digit of our solution. 
Result so far: 126555.988
Subtract 3592 from 3980 to get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Our division results in 126555.988 with a remaining 0.0388.
