We're dividing 901490 by 3 
Our goal is to divide 901490 by 3.

On to step 1:
The number 3 fits into 9 3 times, leaving a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 9 from 9, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 3

Moving on to step 2:
When dividing 0 by 3, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtract 0 from 0 to get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 3

Moving on to step 3:
If we divide 1 by 3, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 300.0
Subtract 0 from 1 to get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 3

Let's proceed to step 4:
If we divide 14 by 3, we get 4 and a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 3004.0
If we take 12 away from 14, we end up with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 3

Going ahead to step 5:
3 can be fit into 29 9 times, resulting in a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 30049.0
Deduct 27 from 29 and we're left with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 3

Step 6:
20 divided by 3 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 300496.0
Subtract 18 from 20 to 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.

Let's proceed to step 7:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 300496.6
Deduct 18 from 20 and we're left 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.

Moving on to step 8:
3 can be fit into 20 6 times, resulting in a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 300496.66
Subtract 18 from 20 to 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.

The final result is 300496.66 with a remainder of 0.002.
