We look at the division of 457258 by 9 
We want to figure out the number of times 457258 can be divided by 9.

Step 1:
9 goes into 4 0 times with 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.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 9

Advancing to step 2:
If we divide 45 by 9, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 0 after subtracting 45 from 45.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 9

Going ahead to step 3:
When dividing 7 by 9, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 9

Moving on to step 4:
9 goes into 72 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 508.0
The remainder is 0 after subtracting 72 from 72.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 9

Let's proceed to step 5:
9 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 5080.0
If we take 0 away from 5, we end up with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 9

Step 6:
When dividing 58 by 9, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 50806.0
If we take 54 away from 58, we end up 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 7:
If we divide 40 by 9, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 50806.4
Subtract 36 from 40 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.

Advancing to step 8:
When dividing 40 by 9, we get 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 50806.44
If we take 36 away from 40, we end up 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.

After the division, we end up with 50806.44 and a remainder of 0.004.
