We divide 431175 by 3
Let's see how many times 3 fits into 431175.

On to step 1:
The number 3 fits into 4 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 3 from 4, we get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 3

Step 2:
If we divide 13 by 3, we get 4 and a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 12 from 13 and we're left with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 3

Let's proceed to step 3:
The number 3 fits into 11 3 times, leaving a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 143.0
If we subtract 9 from 11, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 3

Step 4:
3 goes into 21 7 times with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 1437.0
If we take 21 away from 21, we end up with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 3

Moving on to step 5:
The number 3 fits into 7 2 times, leaving a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 14372.0
If we take 6 away from 7, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 3

Step 6:
15 divided by 3 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 143725.0
If we take 15 away from 15, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 143725.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
If we divide 0 by 3, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 143725.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 143725.0 and a remainder of 0.0.
