We're dividing 475671 by 3 
Let's see how many times 3 fits into 475671.

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
Deduct 3 from 4 and we're left with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 3

On to step 2:
When dividing 17 by 3, we get 5 with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtract 15 from 17 to get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 3

Advancing to step 3:
When dividing 25 by 3, we get 8 with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 158.0
Subtract 24 from 25 to get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 3

On to step 4:
3 can be fit into 16 5 times, resulting in a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 1585.0
If we subtract 15 from 16, we get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 3

On to step 5:
17 divided by 3 is 5 with a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 15855.0
Subtracting 15 from 17 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 3

Moving on to step 6:
When dividing 21 by 3, we get 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 158557.0
If we subtract 21 from 21, we get 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 7:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 158557.0
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.

Going ahead to step 8:
If we divide 0 by 3, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 158557.0
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.

The final result is 158557.0 with a remainder of 0.0.
