We look at the division of 953964 by 3 
We're looking to find how many times 3 goes into 953964.

Advancing to step 1:
The number 3 fits into 9 3 times, leaving a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 9 from 9, we get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 3

Going ahead to step 2:
3 goes into 5 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 31.0
The remainder is 2 after subtracting 3 from 5.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 3

Moving on to step 3:
3 can be fit into 23 7 times, resulting in a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 317.0
Deduct 21 from 23 and we're left with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 3

Going ahead to step 4:
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: 3179.0
Subtracting 27 from 29 leaves us with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 3

Let's proceed to step 5:
The number 3 fits into 26 8 times, leaving a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 31798.0
Deduct 24 from 26 and we're left with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 3

Let's proceed to step 6:
When dividing 24 by 3, we get 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 317988.0
Subtract 24 from 24 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 7:
When dividing 0 by 3, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 317988.0
Subtracting 0 from 0 leaves us 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.

Going ahead to step 8:
3 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 317988.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 317988.0 with a remaining 0.0.
