3579662 ÷ 668 
Our goal is to divide 3579662 by 668.

Advancing to step 1:
If we divide 3 by 668, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 668

Let's proceed to step 2:
When dividing 35 by 668, we get 0 with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Take the next digit (7) from the dividend and append it to 35, then repeat: 357 / 668

On to step 3:
668 can be fit into 357 0 times, resulting in a remainder of 357.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 357 leaves us with 357.
Take the next digit (9) from the dividend and append it to 357, then repeat: 3579 / 668

Advancing to step 4:
3579 divided by 668 is 5 with a remainder of 239.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 3340 from 3579, we get 239.
Fetch the next digit (6) from the dividend, attach it to 239 and continue: 2396 / 668

Let's proceed to step 5:
If we divide 2396 by 668, we get 3 and a remainder of 392.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
Subtracting 2004 from 2396 leaves us with 392.
Append the next digit (6) from the dividend to 392 and continue with: 3926 / 668

Step 6:
The number 668 fits into 3926 5 times, leaving a remainder of 586.
The number 5 becomes the next digit in our result. 
Result so far: 535.0
Subtracting 3340 from 3926 leaves us with 586.
Include the next digit (2) from the dividend after 586, then repeat: 5862 / 668

Going ahead to step 7:
If we divide 5862 by 668, we get 8 and a remainder of 518.
Put 8 as the next digit of the answer. 
Result so far: 5358.0
If we subtract 5344 from 5862, we get 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

On to step 8:
When dividing 5180 by 668, we get 7 with a remainder of 504.
Put 7 as the next digit of the answer. 
Result so far: 5358.7
If we take 4676 away from 5180, we end up with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Advancing to step 9:
When dividing 5040 by 668, we get 7 with a remainder of 364.
Use 7 as the next digit of our solution. 
Result so far: 5358.77
Subtracting 4676 from 5040 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

After the division, we end up with 5358.77 and a remainder of 0.364.
