We look at the division of 805215 by 458 
Our goal is to divide 805215 by 458.

Moving on to step 1:
The number 458 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 458

On to step 2:
80 divided by 458 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Fetch the next digit (5) from the dividend, attach it to 80 and continue: 805 / 458

Going ahead to step 3:
When dividing 805 by 458, we get 1 with a remainder of 347.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 458 from 805 and we're left with 347.
Append the next digit (2) from the dividend to 347 and continue with: 3472 / 458

Step 4:
3472 divided by 458 is 7 with a remainder of 266.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
The remainder is 266 after subtracting 3206 from 3472.
Fetch the next digit (1) from the dividend, attach it to 266 and continue: 2661 / 458

Moving on to step 5:
The number 458 fits into 2661 5 times, leaving a remainder of 371.
Write down 5 as next digit of the result. 
Result so far: 175.0
Subtract 2290 from 2661 to get 371.
Append the next digit (5) from the dividend to 371 and continue with: 3715 / 458

Moving on to step 6:
3715 divided by 458 is 8 with a remainder of 51.
Use 8 as the next digit of our solution. 
Result so far: 1758.0
If we take 3664 away from 3715, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 7:
The number 458 fits into 510 1 times, leaving a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 1758.1
If we take 458 away from 510, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 8:
The number 458 fits into 520 1 times, leaving a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 1758.11
The remainder is 62 after subtracting 458 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Our division results in 1758.11 with a remaining 0.062.
