We divide 395128 by 3
Our goal is to divide 395128 by 3.

Going ahead to step 1:
3 divided by 3 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 3 from 3, we get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 3

Advancing to step 2:
9 divided by 3 is 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 9 from 9 and we're left with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 3

Let's proceed to step 3:
When dividing 5 by 3, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 131.0
If we take 3 away from 5, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 3

Moving on to step 4:
21 divided by 3 is 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 1317.0
If we take 21 away from 21, we end up with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 3

Advancing to step 5:
2 divided by 3 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 13170.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 3

Advancing to step 6:
3 can be fit into 28 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 131709.0
Deduct 27 from 28 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.

Going ahead 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: 131709.3
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.

Let's proceed to step 8:
3 goes into 10 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 131709.33
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.

Our division results in 131709.33 with a remaining 0.001.
