Let's divide 381868 by 3
We want to figure out the number of times 381868 can be divided by 3.

Moving on to step 1:
3 can be fit into 3 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 3 from 3 leaves us with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 3

Advancing to step 2:
When dividing 8 by 3, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 6 away from 8, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 3

On to step 3:
21 divided by 3 is 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 127.0
If we subtract 21 from 21, we get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 3

Going ahead to step 4:
3 can be fit into 8 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 1272.0
If we subtract 6 from 8, we get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 3

On to step 5:
When dividing 26 by 3, we get 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 12728.0
Deduct 24 from 26 and we're left with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 3

Going ahead to step 6:
28 divided by 3 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 127289.0
Subtract 27 from 28 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.

On to step 7:
3 goes into 10 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 127289.3
If we take 9 away from 10, we end up 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.

On to step 8:
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: 127289.33
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.

The final result is 127289.33 with a remainder of 0.001.
