We divide 963916 by 3
Let's see how many times 3 fits into 963916.

Moving on to step 1:
When dividing 9 by 3, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 9 from 9 and we're left with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 3

Moving on to step 2:
When dividing 6 by 3, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
If we take 6 away from 6, we end up with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 3

Step 3:
3 can be fit into 3 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 321.0
The remainder is 0 after subtracting 3 from 3.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 3

Advancing to step 4:
When dividing 9 by 3, we get 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3213.0
Subtracting 9 from 9 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 3

Advancing to step 5:
1 divided by 3 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 32130.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 3

Step 6:
16 divided by 3 is 5 with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 321305.0
The remainder is 1 after subtracting 15 from 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 321305.3
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.

On to step 8:
10 divided by 3 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 321305.33
Deduct 9 from 10 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.

The quotient of the division is 321305.33, and the remainder is 0.001.
