We divide 661786 by 3
Let's see how many times 3 fits into 661786.

Let's proceed to step 1:
If we divide 6 by 3, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 6 from 6 to get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 3

On to step 2:
3 can be fit into 6 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Subtracting 6 from 6 leaves us with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 3

Moving on to step 3:
3 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 220.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 3

Let's proceed to step 4:
If we divide 17 by 3, we get 5 and a remainder of 2.
The next digit of our result is 5. 
Result so far: 2205.0
If we take 15 away from 17, we end up with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 3

Let's proceed to step 5:
3 goes into 28 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 22059.0
If we take 27 away from 28, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 3

Advancing to step 6:
When dividing 16 by 3, we get 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 220595.0
Deduct 15 from 16 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 7:
If we divide 10 by 3, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 220595.3
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.

Going ahead to step 8:
When dividing 10 by 3, we get 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 220595.33
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.

Our division results in 220595.33 with a remaining 0.001.
