18123184 divided by 448 
Our goal is to divide 18123184 by 448.

Let's proceed to step 1:
1 divided by 448 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 448

Step 2:
18 divided by 448 is 0 with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 448

Moving on to step 3:
181 divided by 448 is 0 with a remainder of 181.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 181 after subtracting 0 from 181.
Append the next digit (2) from the dividend to 181 and continue with: 1812 / 448

Step 4:
448 can be fit into 1812 4 times, resulting in a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 1792 from 1812 leaves us with 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 448

Let's proceed to step 5:
203 divided by 448 is 0 with a remainder of 203.
Use 0 as the next digit of our solution. 
Result so far: 40.0
If we take 0 away from 203, we end up with 203.
Grab the next digit (1) from the dividend, add it to 203, then carry on: 2031 / 448

On to step 6:
2031 divided by 448 is 4 with a remainder of 239.
Record the quotient 4 as the next digit in the result. 
Result so far: 404.0
Subtracting 1792 from 2031 leaves us with 239.
Include the next digit (8) from the dividend after 239, then repeat: 2398 / 448

Step 7:
448 goes into 2398 5 times with a remainder of 158.
Write down 5 as next digit of the result. 
Result so far: 4045.0
The remainder is 158 after subtracting 2240 from 2398.
Grab the next digit (4) from the dividend, add it to 158, then carry on: 1584 / 448

Going ahead to step 8:
448 can be fit into 1584 3 times, resulting in a remainder of 240.
Use 3 as the next digit of our solution. 
Result so far: 40453.0
Subtracting 1344 from 1584 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 9:
The number 448 fits into 2400 5 times, leaving a remainder of 160.
Record the quotient 5 as the next digit in the result. 
Result so far: 40453.5
If we subtract 2240 from 2400, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 10:
448 goes into 1600 3 times with a remainder of 256.
Put 3 as the next digit of the answer. 
Result so far: 40453.53
If we subtract 1344 from 1600, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 11:
448 can be fit into 2560 5 times, resulting in a remainder of 320.
Write down 5 as next digit of the result. 
Result so far: 40453.535
Subtract 2240 from 2560 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 12:
The number 448 fits into 3200 7 times, leaving a remainder of 64.
Record the quotient 7 as the next digit in the result. 
Result so far: 40453.5357
If we take 3136 away from 3200, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 13:
If we divide 640 by 448, we get 1 and a remainder of 192.
Record the quotient 1 as the next digit in the result. 
Result so far: 40453.53571
If we take 448 away from 640, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 14:
1920 divided by 448 is 4 with a remainder of 128.
Use 4 as the next digit of our solution. 
Result so far: 40453.535714
If we take 1792 away from 1920, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 15:
1280 divided by 448 is 2 with a remainder of 384.
Put 2 as the next digit of the answer. 
Result so far: 40453.5357142
If we subtract 896 from 1280, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 16:
448 goes into 3840 8 times with a remainder of 256.
Record the quotient 8 as the next digit in the result. 
Result so far: 40453.53571428
Subtract 3584 from 3840 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The quotient of the division is 40453.53571428, and the remainder is 2.56e-07.
