We're dividing 18318978 by 408 
We want to divide 18318978 by 408.

Advancing to step 1:
If we divide 1 by 408, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 408

Moving on to step 2:
408 goes into 18 0 times with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 408

Step 3:
If we divide 183 by 408, we get 0 and a remainder of 183.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 183 and we're left with 183.
Append the next digit (1) from the dividend to 183 and continue with: 1831 / 408

Let's proceed to step 4:
408 goes into 1831 4 times with a remainder of 199.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 199 after subtracting 1632 from 1831.
Fetch the next digit (8) from the dividend, attach it to 199 and continue: 1998 / 408

Going ahead to step 5:
When dividing 1998 by 408, we get 4 with a remainder of 366.
The next digit of our result is 4. 
Result so far: 44.0
If we subtract 1632 from 1998, we get 366.
Include the next digit (9) from the dividend after 366, then repeat: 3669 / 408

Step 6:
If we divide 3669 by 408, we get 8 and a remainder of 405.
Write down 8 as next digit of the result. 
Result so far: 448.0
If we take 3264 away from 3669, we end up with 405.
Bring next digit (7) of the dividend behind the 405 and repeat the process: 4057 / 408

Let's proceed to step 7:
The number 408 fits into 4057 9 times, leaving a remainder of 385.
The next digit of our result is 9. 
Result so far: 4489.0
Subtract 3672 from 4057 to get 385.
Include the next digit (8) from the dividend after 385, then repeat: 3858 / 408

On to step 8:
The number 408 fits into 3858 9 times, leaving a remainder of 186.
Write down 9 as next digit of the result. 
Result so far: 44899.0
Deduct 3672 from 3858 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 9:
408 can be fit into 1860 4 times, resulting in a remainder of 228.
Record the quotient 4 as the next digit in the result. 
Result so far: 44899.4
The remainder is 228 after subtracting 1632 from 1860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Advancing to step 10:
408 goes into 2280 5 times with a remainder of 240.
The next digit of our result is 5. 
Result so far: 44899.45
If we take 2040 away from 2280, we end up 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.

Step 11:
2400 divided by 408 is 5 with a remainder of 360.
Record the quotient 5 as the next digit in the result. 
Result so far: 44899.455
Subtract 2040 from 2400 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The quotient of the division is 44899.455, and the remainder is 0.036.
