We look at the division of 458438 by 6 
Let's see how many times 6 fits into 458438.

Moving on to step 1:
6 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 6

Advancing to step 2:
6 goes into 45 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 42 from 45 to get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 6

Moving on to step 3:
6 goes into 38 6 times with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 76.0
Subtracting 36 from 38 leaves us with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 6

Moving on to step 4:
The number 6 fits into 24 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 764.0
Subtract 24 from 24 to get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 6

On to step 5:
If we divide 3 by 6, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 7640.0
If we take 0 away from 3, we end up with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 6

Let's proceed to step 6:
When dividing 38 by 6, we get 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 76406.0
Subtracting 36 from 38 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
If we divide 20 by 6, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 76406.3
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
If we divide 20 by 6, we get 3 and a remainder of 2.
The next digit of our result is 3. 
Result so far: 76406.33
Subtracting 18 from 20 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 76406.33 with a remainder of 0.002.
