We look at the division of 429353 by 3 
We want to figure out the number of times 429353 can be divided by 3.

Going ahead to step 1:
If we divide 4 by 3, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 3 from 4 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 3

Advancing 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
If we subtract 12 from 12, we get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 3

Going ahead to step 3:
9 divided by 3 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 143.0
Subtract 9 from 9 to get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 3

Step 4:
3 divided by 3 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1431.0
Subtract 3 from 3 to get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 3

Let's proceed to step 5:
3 can be fit into 5 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 14311.0
Deduct 3 from 5 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 3

On to step 6:
23 divided by 3 is 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 143117.0
If we subtract 21 from 23, 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.

Moving on to step 7:
When dividing 20 by 3, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 143117.6
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.

Advancing to step 8:
20 divided by 3 is 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 143117.66
The remainder is 2 after subtracting 18 from 20.
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 143117.66, with a leftover of 0.002.
