We look at the division of 781598 by 3 
We want to divide 781598 by 3.

On to step 1:
7 divided by 3 is 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 6 from 7 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 3

Step 2:
3 can be fit into 18 6 times, resulting in a remainder of 0.
The next digit of our result is 6. 
Result so far: 26.0
The remainder is 0 after subtracting 18 from 18.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 3

Advancing to step 3:
The number 3 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 260.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 3

Moving on to step 4:
If we divide 15 by 3, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 2605.0
Deduct 15 from 15 and we're left with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 3

Advancing to step 5:
3 goes into 9 3 times with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 26053.0
Subtract 9 from 9 to get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 3

Step 6:
8 divided by 3 is 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 260532.0
If we subtract 6 from 8, 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.

Step 7:
When dividing 20 by 3, we get 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 260532.6
The remainder is 2 after subtracting 18 from 20.
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 8:
If we divide 20 by 3, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 260532.66
If we take 18 away from 20, we end up 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.

Our division results in 260532.66 with a remaining 0.002.
