We look at the division of 429754 by 12 
Our goal is to divide 429754 by 12.

Going ahead to step 1:
If we divide 4 by 12, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 12

Going ahead to step 2:
The number 12 fits into 42 3 times, leaving a remainder of 6.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 36 from 42 to get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 12

Moving on to step 3:
12 goes into 69 5 times with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
The remainder is 9 after subtracting 60 from 69.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 12

Going ahead to step 4:
The number 12 fits into 97 8 times, leaving a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 358.0
Subtract 96 from 97 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 12

Let's proceed to step 5:
12 goes into 15 1 times with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 3581.0
Deduct 12 from 15 and we're left with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 12

Going ahead to step 6:
12 goes into 34 2 times with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 35812.0
Subtract 24 from 34 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
If we divide 100 by 12, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 35812.8
Subtract 96 from 100 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 35812.83
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
If we divide 40 by 12, we get 3 and a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 35812.833
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 35812.833 with a remainder of 0.0004.
