435940 divided by 3 
We want to divide 435940 by 3.

Going ahead to step 1:
4 divided by 3 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 3 from 4 leaves us with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 3

Advancing to step 2:
13 divided by 3 is 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 1 after subtracting 12 from 13.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 3

Step 3:
If we divide 15 by 3, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 145.0
If we take 15 away from 15, we end up with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 3

Step 4:
9 divided by 3 is 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 1453.0
Subtract 9 from 9 to get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 3

On to step 5:
The number 3 fits into 4 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 14531.0
Subtract 3 from 4 to get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 3

Step 6:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 145313.0
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.

Step 7:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 145313.3
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
10 divided by 3 is 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 145313.33
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 outcome is 145313.33, with a leftover of 0.001.
