Let's divide 434145 by 9
We want to divide 434145 by 9.

Going ahead to step 1:
When dividing 4 by 9, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 9

Moving on to step 2:
9 can be fit into 43 4 times, resulting in a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 36 from 43 leaves us with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 9

Step 3:
9 goes into 74 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
If we subtract 72 from 74, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 9

Let's proceed to step 4:
9 goes into 21 2 times with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 482.0
If we subtract 18 from 21, we get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 9

On to step 5:
34 divided by 9 is 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 4823.0
Subtracting 27 from 34 leaves us with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 9

Going ahead to step 6:
When dividing 75 by 9, we get 8 with a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 48238.0
If we take 72 away from 75, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
9 can be fit into 30 3 times, resulting in a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 48238.3
The remainder is 3 after subtracting 27 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
If we divide 30 by 9, we get 3 and a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 48238.33
Deduct 27 from 30 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 48238.33 and a remainder of 0.003.
