We're dividing 550888 by 86 
Our goal is to divide 550888 by 86.

Advancing to step 1:
The number 86 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 86

On to step 2:
When dividing 55 by 86, we get 0 with a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Fetch the next digit (0) from the dividend, attach it to 55 and continue: 550 / 86

Moving on to step 3:
86 can be fit into 550 6 times, resulting in a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 516 from 550 to get 34.
Append the next digit (8) from the dividend to 34 and continue with: 348 / 86

Step 4:
86 can be fit into 348 4 times, resulting in a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 64.0
If we take 344 away from 348, we end up with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 86

Advancing to step 5:
When dividing 48 by 86, we get 0 with a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 640.0
Subtract 0 from 48 to get 48.
Bring next digit (8) of the dividend behind the 48 and repeat the process: 488 / 86

Moving on to step 6:
86 can be fit into 488 5 times, resulting in a remainder of 58.
The next digit of our result is 5. 
Result so far: 6405.0
If we subtract 430 from 488, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 7:
86 goes into 580 6 times with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 6405.6
Subtracting 516 from 580 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 8:
86 goes into 640 7 times with a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 6405.67
Subtracting 602 from 640 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
86 can be fit into 380 4 times, resulting in a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 6405.674
If we take 344 away from 380, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 10:
360 divided by 86 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 6405.6744
Subtract 344 from 360 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 6405.6744 and a remainder of 0.00016.
