We're dividing 566211 by 86 
We want to figure out the number of times 566211 can be divided by 86.

Let's proceed to step 1:
86 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 86

Moving on to step 2:
If we divide 56 by 86, we get 0 and a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 56 to get 56.
Take the next digit (6) from the dividend and append it to 56, then repeat: 566 / 86

Moving on to step 3:
The number 86 fits into 566 6 times, leaving a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 516 from 566, we get 50.
Take the next digit (2) from the dividend and append it to 50, then repeat: 502 / 86

Moving on to step 4:
502 divided by 86 is 5 with a remainder of 72.
The next digit of our result is 5. 
Result so far: 65.0
If we subtract 430 from 502, we get 72.
Append the next digit (1) from the dividend to 72 and continue with: 721 / 86

Advancing to step 5:
721 divided by 86 is 8 with a remainder of 33.
Write down 8 as next digit of the result. 
Result so far: 658.0
If we subtract 688 from 721, we get 33.
Grab the next digit (1) from the dividend, add it to 33, then carry on: 331 / 86

On to step 6:
331 divided by 86 is 3 with a remainder of 73.
The next digit of our result is 3. 
Result so far: 6583.0
Subtracting 258 from 331 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 7:
86 can be fit into 730 8 times, resulting in a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 6583.8
The remainder is 42 after subtracting 688 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 8:
The number 86 fits into 420 4 times, leaving a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 6583.84
If we subtract 344 from 420, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 9:
When dividing 760 by 86, we get 8 with a remainder of 72.
The next digit of our result is 8. 
Result so far: 6583.848
Deduct 688 from 760 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 10:
86 can be fit into 720 8 times, resulting in a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 6583.8488
If we take 688 away from 720, 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.

The final outcome is 6583.8488, with a leftover of 0.00032.
