We look at the division of 581662 by 86 
We're looking to find how many times 86 goes into 581662.

Step 1:
5 divided by 86 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 86

Going ahead to step 2:
When dividing 58 by 86, we get 0 with a remainder of 58.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 58, we end up with 58.
Fetch the next digit (1) from the dividend, attach it to 58 and continue: 581 / 86

Step 3:
When dividing 581 by 86, we get 6 with a remainder of 65.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 516 from 581 leaves us with 65.
Fetch the next digit (6) from the dividend, attach it to 65 and continue: 656 / 86

On to step 4:
When dividing 656 by 86, we get 7 with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
Deduct 602 from 656 and we're left with 54.
Fetch the next digit (6) from the dividend, attach it to 54 and continue: 546 / 86

Going ahead to step 5:
86 goes into 546 6 times with a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 676.0
Deduct 516 from 546 and we're left with 30.
Take the next digit (2) from the dividend and append it to 30, then repeat: 302 / 86

Advancing to step 6:
302 divided by 86 is 3 with a remainder of 44.
Record the quotient 3 as the next digit in the result. 
Result so far: 6763.0
If we take 258 away from 302, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 7:
The number 86 fits into 440 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 6763.5
Deduct 430 from 440 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
The number 86 fits into 100 1 times, leaving a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 6763.51
Subtract 86 from 100 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 9:
The number 86 fits into 140 1 times, leaving a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 6763.511
Subtract 86 from 140 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final outcome is 6763.511, with a leftover of 0.0054.
