661910 divided by 3 
Let's see how many times 3 fits into 661910.

Going ahead to step 1:
3 can be fit into 6 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 6 from 6 to get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 3

On to step 2:
When dividing 6 by 3, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
The remainder is 0 after subtracting 6 from 6.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 3

Let's proceed to step 3:
3 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 220.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 3

Step 4:
19 divided by 3 is 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 2206.0
Deduct 18 from 19 and we're left with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 3

On to step 5:
3 can be fit into 11 3 times, resulting in a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 22063.0
If we take 9 away from 11, we end up with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 3

Advancing to step 6:
20 divided by 3 is 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 220636.0
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
When dividing 20 by 3, we get 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 220636.6
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
20 divided by 3 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 220636.66
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 220636.66, and the remainder is 0.002.
