We're dividing 640036 by 18 
We want to figure out the number of times 640036 can be divided by 18.

Step 1:
If we divide 6 by 18, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 18

Advancing to step 2:
18 goes into 64 3 times with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 54 away from 64, we end up with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 18

Let's proceed to step 3:
18 goes into 100 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Subtracting 90 from 100 leaves us with 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 18

Moving on to step 4:
18 can be fit into 100 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 355.0
If we subtract 90 from 100, we get 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 18

Moving on to step 5:
18 goes into 103 5 times with a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 3555.0
The remainder is 13 after subtracting 90 from 103.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 18

Step 6:
136 divided by 18 is 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 35557.0
If we subtract 126 from 136, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
If we divide 100 by 18, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 35557.5
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
The number 18 fits into 100 5 times, leaving a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 35557.55
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 35557.55 with a remainder of 0.01.
