Let's divide 779640 by 3
We're looking to find how many times 3 goes into 779640.

Step 1:
3 can be fit into 7 2 times, resulting in a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 6 from 7 to get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 3

Let's proceed to step 2:
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: 25.0
Subtract 15 from 17 to get 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 3

Going ahead to step 3:
3 goes into 29 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 259.0
Subtract 27 from 29 to get 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 3

Advancing to step 4:
3 goes into 26 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 2598.0
Subtracting 24 from 26 leaves us with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 3

Moving on to step 5:
3 goes into 24 8 times with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 25988.0
If we take 24 away from 24, we end up with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 3

Step 6:
0 divided by 3 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 259880.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 259880.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
0 divided by 3 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 259880.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 259880.0, with a leftover of 0.0.
