640411 ÷ 18 
We want to divide 640411 by 18.

Moving on to step 1:
The number 18 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 18

Let's proceed to step 2:
18 can be fit into 64 3 times, resulting in a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 54 from 64 leaves us with 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 18

Let's proceed to step 3:
18 goes into 100 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Deduct 90 from 100 and we're left with 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 18

Going ahead to step 4:
When dividing 104 by 18, we get 5 with a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 355.0
Deduct 90 from 104 and we're left with 14.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 18

Going ahead to step 5:
The number 18 fits into 141 7 times, leaving a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 3557.0
If we take 126 away from 141, we end up with 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 18

Let's proceed to step 6:
If we divide 151 by 18, we get 8 and a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 35578.0
If we take 144 away from 151, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
70 divided by 18 is 3 with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 35578.3
If we subtract 54 from 70, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
18 can be fit into 160 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 35578.38
Subtracting 144 from 160 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
18 goes into 160 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 35578.388
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 35578.388 with a balance of 0.0016.
