We divide 666790 by 3
We're looking to find how many times 3 goes into 666790.

On to step 1:
6 divided by 3 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 0 after subtracting 6 from 6.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 3

Advancing to step 2:
The number 3 fits into 6 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 22.0
Deduct 6 from 6 and we're left with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 3

Let's proceed to step 3:
3 goes into 6 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 222.0
Subtracting 6 from 6 leaves us with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 3

Step 4:
3 goes into 7 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2222.0
Subtracting 6 from 7 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 3

Step 5:
3 can be fit into 19 6 times, resulting in a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 22226.0
Subtract 18 from 19 to get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 3

Advancing to step 6:
3 goes into 10 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 222263.0
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
When dividing 10 by 3, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 222263.3
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
The number 3 fits into 10 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 222263.33
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 222263.33 and a remainder of 0.001.
