Let's divide 429401 by 3
Let's see how many times 3 fits into 429401.

Let's proceed to step 1:
3 can be fit into 4 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 3 from 4, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 3

Going ahead to step 2:
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: 14.0
Subtracting 12 from 12 leaves us with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 3

Going ahead to step 3:
3 can be fit into 9 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 143.0
The remainder is 0 after subtracting 9 from 9.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 3

Let's proceed to step 4:
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: 1431.0
If we subtract 3 from 4, we get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 3

Moving on to step 5:
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: 14313.0
The remainder is 1 after subtracting 9 from 10.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 3

Moving on to step 6:
3 can be fit into 11 3 times, resulting in a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 143133.0
If we subtract 9 from 11, 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.

Step 7:
3 goes into 20 6 times with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 143133.6
If we subtract 18 from 20, 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 8:
3 goes into 20 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 143133.66
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.

Our division results in 143133.66 with a remaining 0.002.
