We look at the division of 458718 by 5 
We're looking to find how many times 5 goes into 458718.

On to step 1:
5 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
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 / 5

On to step 2:
5 can be fit into 45 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 45 from 45 leaves us with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 5

Going ahead to step 3:
When dividing 8 by 5, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 91.0
The remainder is 3 after subtracting 5 from 8.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 5

Advancing to step 4:
If we divide 37 by 5, we get 7 and a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 917.0
If we take 35 away from 37, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 5

Going ahead to step 5:
The number 5 fits into 21 4 times, leaving a remainder of 1.
The next digit of our result is 4. 
Result so far: 9174.0
Subtracting 20 from 21 leaves us with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 5

Step 6:
The number 5 fits into 18 3 times, leaving a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 91743.0
Deduct 15 from 18 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
5 can be fit into 30 6 times, resulting in a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 91743.6
Deduct 30 from 30 and we're left 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.

Advancing to step 8:
When dividing 0 by 5, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 91743.6
Subtracting 0 from 0 leaves us 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.

On to step 9:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 91743.6
Deduct 0 from 0 and we're left 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.

The final result is 91743.6 with a remainder of 0.0.
