Let's divide 356806 by 3
We're looking to find how many times 3 goes into 356806.

Step 1:
3 divided by 3 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 3 away from 3, we end up with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 3

Moving on to step 2:
When dividing 5 by 3, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 3 away from 5, we end up with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 3

Let's proceed to step 3:
3 can be fit into 26 8 times, resulting in a remainder of 2.
The next digit of our result is 8. 
Result so far: 118.0
Deduct 24 from 26 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 3

Going ahead to step 4:
The number 3 fits into 28 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 1189.0
If we subtract 27 from 28, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 3

On to step 5:
10 divided by 3 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 11893.0
If we take 9 away from 10, we end up with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 3

On to step 6:
When dividing 16 by 3, we get 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 118935.0
If we take 15 away from 16, 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 7:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 118935.3
If we subtract 9 from 10, 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.

Step 8:
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: 118935.33
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 final result is 118935.33 with a remainder of 0.001.
