Let's divide 442387 by 3
We want to divide 442387 by 3.

Going ahead to step 1:
3 can be fit into 4 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 3 from 4 to get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 3

Step 2:
3 can be fit into 14 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 12 from 14 to get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 3

Advancing to step 3:
When dividing 22 by 3, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 147.0
The remainder is 1 after subtracting 21 from 22.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 3

Going ahead to step 4:
13 divided by 3 is 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 1474.0
The remainder is 1 after subtracting 12 from 13.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 3

Moving on to step 5:
3 can be fit into 18 6 times, resulting in a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 14746.0
If we take 18 away from 18, we end up with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 3

Let's proceed to step 6:
7 divided by 3 is 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 147462.0
Subtract 6 from 7 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.

Let's proceed to step 7:
When dividing 10 by 3, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 147462.3
Subtracting 9 from 10 leaves us 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:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 147462.33
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.

The final result is 147462.33 with a remainder of 0.001.
