370286 ÷ 3 
Let's see how many times 3 fits into 370286.

Step 1:
3 can be fit into 3 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 3 from 3 and we're left with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 3

Let's proceed to step 2:
The number 3 fits into 7 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 6 from 7 to get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 3

Moving on to step 3:
If we divide 10 by 3, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
If we take 9 away from 10, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 3

Step 4:
12 divided by 3 is 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 1234.0
Deduct 12 from 12 and we're left with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 3

Going ahead to step 5:
8 divided by 3 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 12342.0
Subtracting 6 from 8 leaves us with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 3

Let's proceed to step 6:
The number 3 fits into 26 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 123428.0
If we subtract 24 from 26, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
If we divide 20 by 3, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 123428.6
Subtracting 18 from 20 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
If we divide 20 by 3, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 123428.66
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 123428.66, with a leftover of 0.002.
