We're dividing 393595 by 3 
We want to figure out the number of times 393595 can be divided by 3.

Let's proceed to step 1:
3 can be fit into 3 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 3 from 3 and we're left with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 3

Step 2:
When dividing 9 by 3, we get 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 0 after subtracting 9 from 9.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 3

On to step 3:
The number 3 fits into 3 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 131.0
The remainder is 0 after subtracting 3 from 3.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 3

Advancing to step 4:
When dividing 5 by 3, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1311.0
If we take 3 away from 5, we end up with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 3

Advancing to step 5:
When dividing 29 by 3, we get 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 13119.0
Subtract 27 from 29 to get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 3

Advancing to step 6:
When dividing 25 by 3, we get 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 131198.0
If we subtract 24 from 25, we 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.

Moving on to step 7:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 131198.3
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.

Moving on to step 8:
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: 131198.33
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 outcome is 131198.33, with a leftover of 0.001.
