670660 divided by 4 
We're looking to find how many times 4 goes into 670660.

Moving on 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
The remainder is 2 after subtracting 4 from 6.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 4

Going ahead to step 2:
27 divided by 4 is 6 with a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtract 24 from 27 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 4

Advancing to step 3:
4 can be fit into 30 7 times, resulting in a remainder of 2.
The next digit of our result is 7. 
Result so far: 167.0
Subtracting 28 from 30 leaves us with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 4

Let's proceed to step 4:
If we divide 26 by 4, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 1676.0
If we take 24 away from 26, we end up with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 4

Let's proceed to step 5:
26 divided by 4 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 16766.0
If we subtract 24 from 26, we get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 4

Let's proceed to step 6:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 167665.0
Subtracting 20 from 20 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:
If we divide 0 by 4, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 167665.0
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.

Advancing to step 8:
4 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 167665.0
Deduct 0 from 0 and we're left 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.

After the division, we end up with 167665.0 and a remainder of 0.0.
