18378741 divided by 448 
We want to divide 18378741 by 448.

Going ahead to step 1:
448 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 448

Let's proceed to step 2:
When dividing 18 by 448, we get 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 448

Step 3:
183 divided by 448 is 0 with a remainder of 183.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 183, we get 183.
Bring next digit (7) of the dividend behind the 183 and repeat the process: 1837 / 448

Step 4:
When dividing 1837 by 448, we get 4 with a remainder of 45.
The next digit of our result is 4. 
Result so far: 4.0
If we take 1792 away from 1837, we end up with 45.
Append the next digit (8) from the dividend to 45 and continue with: 458 / 448

On to step 5:
The number 448 fits into 458 1 times, leaving a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 41.0
Subtract 448 from 458 to get 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 448

Let's proceed to step 6:
When dividing 107 by 448, we get 0 with a remainder of 107.
Put 0 as the next digit of the answer. 
Result so far: 410.0
Subtracting 0 from 107 leaves us with 107.
Append the next digit (4) from the dividend to 107 and continue with: 1074 / 448

Step 7:
The number 448 fits into 1074 2 times, leaving a remainder of 178.
Put 2 as the next digit of the answer. 
Result so far: 4102.0
Subtract 896 from 1074 to get 178.
Bring next digit (1) of the dividend behind the 178 and repeat the process: 1781 / 448

Moving on to step 8:
If we divide 1781 by 448, we get 3 and a remainder of 437.
Record the quotient 3 as the next digit in the result. 
Result so far: 41023.0
Subtracting 1344 from 1781 leaves us with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Going ahead to step 9:
If we divide 4370 by 448, we get 9 and a remainder of 338.
The number 9 becomes the next digit in our result. 
Result so far: 41023.9
Deduct 4032 from 4370 and we're left with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Going ahead to step 10:
The number 448 fits into 3380 7 times, leaving a remainder of 244.
Record the quotient 7 as the next digit in the result. 
Result so far: 41023.97
Deduct 3136 from 3380 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Let's proceed to step 11:
If we divide 2440 by 448, we get 5 and a remainder of 200.
Use 5 as the next digit of our solution. 
Result so far: 41023.975
Subtract 2240 from 2440 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 12:
When dividing 2000 by 448, we get 4 with a remainder of 208.
Put 4 as the next digit of the answer. 
Result so far: 41023.9754
If we take 1792 away from 2000, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

On to step 13:
When dividing 2080 by 448, we get 4 with a remainder of 288.
The next digit of our result is 4. 
Result so far: 41023.97544
Deduct 1792 from 2080 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The final outcome is 41023.97544, with a leftover of 0.000288.
