We look at the division of 784396 by 3 
We want to figure out the number of times 784396 can be divided by 3.

Advancing to step 1:
3 can be fit into 7 2 times, resulting in a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 6 from 7, we get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 3

Moving on to step 2:
The number 3 fits into 18 6 times, leaving a remainder of 0.
The next digit of our result is 6. 
Result so far: 26.0
Subtract 18 from 18 to get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 3

Moving on to step 3:
4 divided by 3 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 261.0
Subtracting 3 from 4 leaves us with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 3

Let's proceed to step 4:
3 goes into 13 4 times with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 2614.0
Subtract 12 from 13 to get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 3

Step 5:
The number 3 fits into 19 6 times, leaving a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 26146.0
Subtract 18 from 19 to get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 3

Going ahead to step 6:
16 divided by 3 is 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 261465.0
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.

Going ahead to step 7:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 261465.3
If we take 9 away from 10, we end up 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 8:
If we divide 10 by 3, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 261465.33
Subtracting 9 from 10 leaves us 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.

Our division results in 261465.33 with a remaining 0.001.
