617945 divided by 3 
Let's see how many times 3 fits into 617945.

Step 1:
When dividing 6 by 3, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 6 from 6, we get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 3

Moving on to step 2:
1 divided by 3 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 3

Going ahead to step 3:
The number 3 fits into 17 5 times, leaving a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 205.0
Deduct 15 from 17 and we're left with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 3

On to step 4:
When dividing 29 by 3, we get 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 2059.0
Deduct 27 from 29 and we're left with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 3

Going ahead to step 5:
If we divide 24 by 3, we get 8 and a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 20598.0
Deduct 24 from 24 and we're left with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 3

Let's proceed to step 6:
3 can be fit into 5 1 times, resulting in a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 205981.0
Subtract 3 from 5 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.

Advancing to step 7:
20 divided by 3 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 205981.6
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.

On to step 8:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 205981.66
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.

The quotient of the division is 205981.66, and the remainder is 0.002.
