We're dividing 455003 by 86 
We want to divide 455003 by 86.

Step 1:
The number 86 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
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

Going ahead to step 2:
If we divide 45 by 86, we get 0 and 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.
Grab the next digit (5) from the dividend, add it to 45, then carry on: 455 / 86

Step 3:
If we divide 455 by 86, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 430 away from 455, we end up with 25.
Fetch the next digit (0) from the dividend, attach it to 25 and continue: 250 / 86

Moving on to step 4:
86 goes into 250 2 times with a remainder of 78.
The next digit of our result is 2. 
Result so far: 52.0
The remainder is 78 after subtracting 172 from 250.
Fetch the next digit (0) from the dividend, attach it to 78 and continue: 780 / 86

On to step 5:
If we divide 780 by 86, we get 9 and a remainder of 6.
The next digit of our result is 9. 
Result so far: 529.0
Subtract 774 from 780 to get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 86

Step 6:
When dividing 63 by 86, we get 0 with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 5290.0
The remainder is 63 after subtracting 0 from 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 7:
630 divided by 86 is 7 with a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 5290.7
Deduct 602 from 630 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
86 goes into 280 3 times with a remainder of 22.
The next digit of our result is 3. 
Result so far: 5290.73
If we take 258 away from 280, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
220 divided by 86 is 2 with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 5290.732
If we subtract 172 from 220, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
The number 86 fits into 480 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 5290.7325
If we take 430 away from 480, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
If we divide 500 by 86, we get 5 and a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 5290.73255
If we subtract 430 from 500, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

In conclusion, the division gives 5290.73255 with a balance of 7e-05.
