429102 divided by 3 
Our goal is to divide 429102 by 3.

Going ahead to step 1:
3 can be fit into 4 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 3 from 4 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 3

Going ahead to step 2:
3 goes into 12 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 12 from 12 to get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 3

On to step 3:
The number 3 fits into 9 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 143.0
Subtract 9 from 9 to get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 3

Moving on to step 4:
When dividing 1 by 3, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 1430.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 3

On to step 5:
The number 3 fits into 10 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 14303.0
Subtracting 9 from 10 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 3

Moving on to step 6:
3 goes into 12 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 143034.0
If we subtract 12 from 12, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
3 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 143034.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 143034.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 143034.0 with a remainder of 0.0.
