We look at the division of 963487 by 3 
We want to figure out the number of times 963487 can be divided by 3.

On to step 1:
The number 3 fits into 9 3 times, leaving a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 9 from 9, we get 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 3

Moving on to step 2:
When dividing 6 by 3, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
If we subtract 6 from 6, we get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 3

Step 3:
If we divide 3 by 3, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 321.0
Deduct 3 from 3 and we're left with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 3

Advancing to step 4:
If we divide 4 by 3, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 3211.0
If we take 3 away from 4, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 3

On to step 5:
The number 3 fits into 18 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 32116.0
If we subtract 18 from 18, we get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 3

Step 6:
When dividing 7 by 3, we get 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 321162.0
Subtracting 6 from 7 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.

Let's proceed to step 7:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 321162.3
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 8:
10 divided by 3 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 321162.33
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 321162.33 with a remainder of 0.001.
