We look at the division of 640712 by 4 
Let's see how many times 4 fits into 640712.

Let's proceed to step 1:
4 goes into 6 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 4 from 6 leaves us with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 4

Going ahead to step 2:
The number 4 fits into 24 6 times, leaving a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we subtract 24 from 24, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 4

On to step 3:
0 divided by 4 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 160.0
If we take 0 away from 0, we end up with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 4

Moving on to step 4:
The number 4 fits into 7 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1601.0
If we take 4 away from 7, we end up with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 4

Let's proceed to step 5:
4 can be fit into 31 7 times, resulting in a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 16017.0
If we take 28 away from 31, we end up with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 4

Moving on to step 6:
4 can be fit into 32 8 times, resulting in a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 160178.0
Subtracting 32 from 32 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
When dividing 0 by 4, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 160178.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
4 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 160178.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 160178.0 and a remainder of 0.0.
