We divide 381252 by 3
We want to figure out the number of times 381252 can be divided by 3.

Moving on to step 1:
The number 3 fits into 3 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 3 away from 3, we end up with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 3

On to step 2:
When dividing 8 by 3, we get 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 2 after subtracting 6 from 8.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 3

Going ahead to step 3:
3 goes into 21 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 127.0
Deduct 21 from 21 and we're left with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 3

Moving on to step 4:
3 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 1270.0
If we take 0 away from 2, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 3

Going ahead to step 5:
25 divided by 3 is 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 12708.0
The remainder is 1 after subtracting 24 from 25.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 3

Going ahead to step 6:
When dividing 12 by 3, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 127084.0
Deduct 12 from 12 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.

On to step 7:
3 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 127084.0
If we subtract 0 from 0, 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.

Step 8:
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: 127084.0
If we take 0 away from 0, 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.

The final result is 127084.0 with a remainder of 0.0.
