Let's divide 403066 by 3
We want to divide 403066 by 3.

Let's proceed to step 1:
When dividing 4 by 3, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 3 from 4 leaves us with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 3

Step 2:
If we divide 10 by 3, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 9 from 10 to get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 3

Let's proceed to step 3:
The number 3 fits into 13 4 times, leaving a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 134.0
The remainder is 1 after subtracting 12 from 13.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 3

Going ahead to step 4:
If we divide 10 by 3, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 1343.0
Deduct 9 from 10 and we're left with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 3

Going ahead to step 5:
The number 3 fits into 16 5 times, leaving a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 13435.0
Subtracting 15 from 16 leaves us with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 3

Advancing to step 6:
16 divided by 3 is 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 134355.0
If we subtract 15 from 16, we 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 can be fit into 10 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 134355.3
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.

Moving on to step 8:
10 divided by 3 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 134355.33
Deduct 9 from 10 and we're left 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.

After the division, we end up with 134355.33 and a remainder of 0.001.
