We're dividing 640212 by 9 
Our goal is to divide 640212 by 9.

Advancing to step 1:
If we divide 6 by 9, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 9

Going ahead to step 2:
9 goes into 64 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 63 away from 64, we end up with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 9

Moving on to step 3:
If we divide 10 by 9, we get 1 and a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 71.0
If we take 9 away from 10, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 9

Advancing to step 4:
12 divided by 9 is 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 711.0
The remainder is 3 after subtracting 9 from 12.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 9

Let's proceed to step 5:
31 divided by 9 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 7113.0
The remainder is 4 after subtracting 27 from 31.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 9

Moving on to step 6:
If we divide 42 by 9, we get 4 and a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 71134.0
The remainder is 6 after subtracting 36 from 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
The number 9 fits into 60 6 times, leaving a remainder of 6.
The next digit of our result is 6. 
Result so far: 71134.6
If we subtract 54 from 60, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
When dividing 60 by 9, we get 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 71134.66
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 71134.66, with a leftover of 0.006.
