Let's divide 550343 by 86
We're looking to find how many times 86 goes into 550343.

Moving on to step 1:
If we divide 5 by 86, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 86

Advancing to step 2:
The number 86 fits into 55 0 times, leaving a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Include the next digit (0) from the dividend after 55, then repeat: 550 / 86

Going ahead to step 3:
86 goes into 550 6 times with a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 516 from 550 leaves us with 34.
Take the next digit (3) from the dividend and append it to 34, then repeat: 343 / 86

On to step 4:
343 divided by 86 is 3 with a remainder of 85.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
The remainder is 85 after subtracting 258 from 343.
Take the next digit (4) from the dividend and append it to 85, then repeat: 854 / 86

Step 5:
When dividing 854 by 86, we get 9 with a remainder of 80.
Use 9 as the next digit of our solution. 
Result so far: 639.0
Deduct 774 from 854 and we're left with 80.
Fetch the next digit (3) from the dividend, attach it to 80 and continue: 803 / 86

On to step 6:
86 goes into 803 9 times with a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 6399.0
The remainder is 29 after subtracting 774 from 803.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 7:
The number 86 fits into 290 3 times, leaving a remainder of 32.
The next digit of our result is 3. 
Result so far: 6399.3
If we take 258 away from 290, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 8:
86 goes into 320 3 times with a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 6399.33
If we subtract 258 from 320, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Our division results in 6399.33 with a remaining 0.062.
