We divide 455145 by 87
Let's see how many times 87 fits into 455145.

Advancing to step 1:
87 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
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 87

Moving on to step 2:
87 can be fit into 45 0 times, resulting in a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Include the next digit (5) from the dividend after 45, then repeat: 455 / 87

Moving on to step 3:
If we divide 455 by 87, we get 5 and a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 20 after subtracting 435 from 455.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 87

Advancing to step 4:
87 goes into 201 2 times with a remainder of 27.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
Deduct 174 from 201 and we're left with 27.
Append the next digit (4) from the dividend to 27 and continue with: 274 / 87

Advancing to step 5:
87 goes into 274 3 times with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 523.0
Subtract 261 from 274 to get 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 87

Moving on to step 6:
87 can be fit into 135 1 times, resulting in a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 5231.0
The remainder is 48 after subtracting 87 from 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 7:
87 goes into 480 5 times with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 5231.5
Deduct 435 from 480 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 8:
When dividing 450 by 87, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 5231.55
If we take 435 away from 450, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 5231.55 with a remainder of 0.015.
