18516251 divided by 455 
Our goal is to divide 18516251 by 455.

Moving on to step 1:
When dividing 1 by 455, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 455

Step 2:
The number 455 fits into 18 0 times, leaving a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 455

Step 3:
455 can be fit into 185 0 times, resulting in a remainder of 185.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 185 and we're left with 185.
Include the next digit (1) from the dividend after 185, then repeat: 1851 / 455

Step 4:
The number 455 fits into 1851 4 times, leaving a remainder of 31.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 31 after subtracting 1820 from 1851.
Take the next digit (6) from the dividend and append it to 31, then repeat: 316 / 455

On to step 5:
316 divided by 455 is 0 with a remainder of 316.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtract 0 from 316 to get 316.
Bring next digit (2) of the dividend behind the 316 and repeat the process: 3162 / 455

Moving on to step 6:
455 can be fit into 3162 6 times, resulting in a remainder of 432.
Record the quotient 6 as the next digit in the result. 
Result so far: 406.0
If we subtract 2730 from 3162, we get 432.
Fetch the next digit (5) from the dividend, attach it to 432 and continue: 4325 / 455

Moving on to step 7:
When dividing 4325 by 455, we get 9 with a remainder of 230.
Use 9 as the next digit of our solution. 
Result so far: 4069.0
The remainder is 230 after subtracting 4095 from 4325.
Take the next digit (1) from the dividend and append it to 230, then repeat: 2301 / 455

Moving on to step 8:
If we divide 2301 by 455, we get 5 and a remainder of 26.
Use 5 as the next digit of our solution. 
Result so far: 40695.0
Subtracting 2275 from 2301 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
When dividing 260 by 455, we get 0 with a remainder of 260.
Record the quotient 0 as the next digit in the result. 
Result so far: 40695.0
If we subtract 0 from 260, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 10:
455 goes into 2600 5 times with a remainder of 325.
The number 5 becomes the next digit in our result. 
Result so far: 40695.05
The remainder is 325 after subtracting 2275 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Advancing to step 11:
455 can be fit into 3250 7 times, resulting in a remainder of 65.
Write down 7 as next digit of the result. 
Result so far: 40695.057
If we take 3185 away from 3250, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 12:
The number 455 fits into 650 1 times, leaving a remainder of 195.
The number 1 becomes the next digit in our result. 
Result so far: 40695.0571
If we take 455 away from 650, we end up with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Let's proceed to step 13:
The number 455 fits into 1950 4 times, leaving a remainder of 130.
The number 4 becomes the next digit in our result. 
Result so far: 40695.05714
Deduct 1820 from 1950 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 14:
The number 455 fits into 1300 2 times, leaving a remainder of 390.
Write down 2 as next digit of the result. 
Result so far: 40695.057142
The remainder is 390 after subtracting 910 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 15:
455 can be fit into 3900 8 times, resulting in a remainder of 260.
The number 8 becomes the next digit in our result. 
Result so far: 40695.0571428
Subtract 3640 from 3900 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 16:
When dividing 2600 by 455, we get 5 with a remainder of 325.
The next digit of our result is 5. 
Result so far: 40695.05714285
The remainder is 325 after subtracting 2275 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

The quotient of the division is 40695.05714285, and the remainder is 3.25e-07.
