We divide 458638 by 86
We're looking to find how many times 86 goes into 458638.

Moving on to step 1:
86 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 86

Moving on to step 2:
86 goes into 45 0 times with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Include the next digit (8) from the dividend after 45, then repeat: 458 / 86

Going ahead to step 3:
458 divided by 86 is 5 with a remainder of 28.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 430 from 458 leaves us with 28.
Bring next digit (6) of the dividend behind the 28 and repeat the process: 286 / 86

Going ahead to step 4:
When dividing 286 by 86, we get 3 with a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
If we take 258 away from 286, we end up with 28.
Bring next digit (3) of the dividend behind the 28 and repeat the process: 283 / 86

Step 5:
86 can be fit into 283 3 times, resulting in a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 533.0
If we take 258 away from 283, we end up with 25.
Append the next digit (8) from the dividend to 25 and continue with: 258 / 86

Moving on to step 6:
When dividing 258 by 86, we get 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 5333.0
If we take 258 away from 258, we end up 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.

Moving on to step 7:
If we divide 0 by 86, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5333.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
86 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5333.0
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.

Our division results in 5333.0 with a remaining 0.0.
