581998 ÷ 86 
Our goal is to divide 581998 by 86.

Going ahead to step 1:
The number 86 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 86

Moving on to step 2:
The number 86 fits into 58 0 times, leaving a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 58 after subtracting 0 from 58.
Include the next digit (1) from the dividend after 58, then repeat: 581 / 86

Moving on to step 3:
86 goes into 581 6 times with a remainder of 65.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 516 from 581 leaves us with 65.
Include the next digit (9) from the dividend after 65, then repeat: 659 / 86

On to step 4:
86 can be fit into 659 7 times, resulting in a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 67.0
Subtracting 602 from 659 leaves us with 57.
Include the next digit (9) from the dividend after 57, then repeat: 579 / 86

Moving on to step 5:
86 can be fit into 579 6 times, resulting in a remainder of 63.
The next digit of our result is 6. 
Result so far: 676.0
If we subtract 516 from 579, we get 63.
Include the next digit (8) from the dividend after 63, then repeat: 638 / 86

On to step 6:
86 can be fit into 638 7 times, resulting in a remainder of 36.
Use 7 as the next digit of our solution. 
Result so far: 6767.0
Subtract 602 from 638 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 7:
If we divide 360 by 86, we get 4 and a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 6767.4
If we subtract 344 from 360, we 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.

Let's proceed to step 8:
The number 86 fits into 160 1 times, leaving a remainder of 74.
Put 1 as the next digit of the answer. 
Result so far: 6767.41
Deduct 86 from 160 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 9:
The number 86 fits into 740 8 times, leaving a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 6767.418
If we take 688 away from 740, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 10:
520 divided by 86 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 6767.4186
If we subtract 516 from 520, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
When dividing 40 by 86, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 6767.4186
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
If we divide 400 by 86, we get 4 and a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 6767.418604
Subtracting 344 from 400 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 13:
86 can be fit into 560 6 times, resulting in a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 6767.4186046
Subtract 516 from 560 to get 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 14:
440 divided by 86 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 6767.41860465
The remainder is 10 after subtracting 430 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 6767.41860465, with a leftover of 1e-08.
