503759 ÷ 86 
We're looking to find how many times 86 goes into 503759.

Going ahead 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
Deduct 0 from 5 and we're left with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 86

Step 2:
The number 86 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 50, we end up with 50.
Include the next digit (3) from the dividend after 50, then repeat: 503 / 86

Advancing to step 3:
The number 86 fits into 503 5 times, leaving a remainder of 73.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 430 from 503 and we're left with 73.
Append the next digit (7) from the dividend to 73 and continue with: 737 / 86

On to step 4:
737 divided by 86 is 8 with a remainder of 49.
Put 8 as the next digit of the answer. 
Result so far: 58.0
Subtract 688 from 737 to get 49.
Bring next digit (5) of the dividend behind the 49 and repeat the process: 495 / 86

Moving on to step 5:
86 can be fit into 495 5 times, resulting in a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 585.0
Subtracting 430 from 495 leaves us with 65.
Fetch the next digit (9) from the dividend, attach it to 65 and continue: 659 / 86

Let's proceed to step 6:
The number 86 fits into 659 7 times, leaving a remainder of 57.
The next digit of our result is 7. 
Result so far: 5857.0
Deduct 602 from 659 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 7:
86 goes into 570 6 times with a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 5857.6
The remainder is 54 after subtracting 516 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 8:
86 can be fit into 540 6 times, resulting in a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 5857.66
Subtract 516 from 540 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 5857.66, with a leftover of 0.024.
