We look at the division of 458254 by 75 
We're looking to find how many times 75 goes into 458254.

Step 1:
75 can be fit into 4 0 times, resulting in 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.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 75

On to step 2:
If we divide 45 by 75, we get 0 and a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Take the next digit (8) from the dividend and append it to 45, then repeat: 458 / 75

On to step 3:
458 divided by 75 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 8 after subtracting 450 from 458.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 75

Step 4:
If we divide 82 by 75, we get 1 and a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 61.0
The remainder is 7 after subtracting 75 from 82.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 75

Going ahead to step 5:
75 can be fit into 75 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 611.0
Subtract 75 from 75 to get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 75

Step 6:
The number 75 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 6110.0
Deduct 0 from 4 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.

Advancing to step 7:
40 divided by 75 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 6110.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
If we divide 400 by 75, we get 5 and a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 6110.05
If we take 375 away from 400, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
The number 75 fits into 250 3 times, leaving a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 6110.053
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 10:
75 goes into 250 3 times with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 6110.0533
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 6110.0533 with a remaining 0.00025.
