We're dividing 354188 by 3 
Let's see how many times 3 fits into 354188.

On to step 1:
3 goes into 3 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 0 after subtracting 3 from 3.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 3

Step 2:
3 can be fit into 5 1 times, resulting in a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 3 from 5 leaves us with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 3

Let's proceed to step 3:
If we divide 24 by 3, we get 8 and a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 118.0
Subtract 24 from 24 to get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 3

Let's proceed to step 4:
The number 3 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 1180.0
If we subtract 0 from 1, we get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 3

Advancing to step 5:
3 goes into 18 6 times with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 11806.0
If we take 18 away from 18, we end up with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 3

Moving on to step 6:
When dividing 8 by 3, we get 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 118062.0
If we subtract 6 from 8, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
If we divide 20 by 3, we get 6 and a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 118062.6
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
20 divided by 3 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 118062.66
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 118062.66 and a remainder of 0.002.
