15383877 ÷ 448 
We want to divide 15383877 by 448.

Step 1:
448 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 448

Step 2:
448 can be fit into 15 0 times, resulting in a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 448

Step 3:
448 goes into 153 0 times with a remainder of 153.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 153 leaves us with 153.
Grab the next digit (8) from the dividend, add it to 153, then carry on: 1538 / 448

On to step 4:
448 can be fit into 1538 3 times, resulting in a remainder of 194.
The next digit of our result is 3. 
Result so far: 3.0
If we take 1344 away from 1538, we end up with 194.
Include the next digit (3) from the dividend after 194, then repeat: 1943 / 448

Moving on to step 5:
448 can be fit into 1943 4 times, resulting in a remainder of 151.
Write down 4 as next digit of the result. 
Result so far: 34.0
If we take 1792 away from 1943, we end up with 151.
Append the next digit (8) from the dividend to 151 and continue with: 1518 / 448

Moving on to step 6:
When dividing 1518 by 448, we get 3 with a remainder of 174.
The number 3 becomes the next digit in our result. 
Result so far: 343.0
Deduct 1344 from 1518 and we're left with 174.
Fetch the next digit (7) from the dividend, attach it to 174 and continue: 1747 / 448

Let's proceed to step 7:
The number 448 fits into 1747 3 times, leaving a remainder of 403.
Use 3 as the next digit of our solution. 
Result so far: 3433.0
If we subtract 1344 from 1747, we get 403.
Grab the next digit (7) from the dividend, add it to 403, then carry on: 4037 / 448

Step 8:
448 can be fit into 4037 9 times, resulting in a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 34339.0
Deduct 4032 from 4037 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
448 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 34339.0
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
The number 448 fits into 500 1 times, leaving a remainder of 52.
Put 1 as the next digit of the answer. 
Result so far: 34339.01
Subtracting 448 from 500 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 11:
If we divide 520 by 448, we get 1 and a remainder of 72.
Put 1 as the next digit of the answer. 
Result so far: 34339.011
If we take 448 away from 520, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 34339.011 with a remainder of 0.0072.
