We're dividing 433251 by 42 
We want to figure out the number of times 433251 can be divided by 42.

Moving on to step 1:
42 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 42

Step 2:
43 divided by 42 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 42 from 43 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 42

Step 3:
If we divide 13 by 42, we get 0 and a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 13 to get 13.
Include the next digit (2) from the dividend after 13, then repeat: 132 / 42

Moving on to step 4:
132 divided by 42 is 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
Subtract 126 from 132 to get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 42

Let's proceed to step 5:
The number 42 fits into 65 1 times, leaving a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1031.0
The remainder is 23 after subtracting 42 from 65.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 42

On to step 6:
The number 42 fits into 231 5 times, leaving a remainder of 21.
Write down 5 as next digit of the result. 
Result so far: 10315.0
The remainder is 21 after subtracting 210 from 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
42 goes into 210 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 10315.5
If we subtract 210 from 210, 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.

Let's proceed to step 8:
When dividing 0 by 42, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10315.5
If we take 0 away from 0, we end up 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.

Step 9:
When dividing 0 by 42, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10315.5
Subtract 0 from 0 to 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.

In conclusion, the division gives 10315.5 with a balance of 0.0.
