507140 ÷ 86 
We're looking to find how many times 86 goes into 507140.

Let's proceed to step 1:
86 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 86

Advancing to step 2:
86 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Grab the next digit (7) from the dividend, add it to 50, then carry on: 507 / 86

Moving on to step 3:
86 can be fit into 507 5 times, resulting in a remainder of 77.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 430 from 507 to get 77.
Take the next digit (1) from the dividend and append it to 77, then repeat: 771 / 86

Advancing to step 4:
If we divide 771 by 86, we get 8 and a remainder of 83.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
If we subtract 688 from 771, we get 83.
Take the next digit (4) from the dividend and append it to 83, then repeat: 834 / 86

Let's proceed to step 5:
If we divide 834 by 86, we get 9 and a remainder of 60.
The next digit of our result is 9. 
Result so far: 589.0
The remainder is 60 after subtracting 774 from 834.
Take the next digit (0) from the dividend and append it to 60, then repeat: 600 / 86

Going ahead to step 6:
86 can be fit into 600 6 times, resulting in a remainder of 84.
The next digit of our result is 6. 
Result so far: 5896.0
If we take 516 away from 600, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 7:
The number 86 fits into 840 9 times, leaving a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 5896.9
Subtracting 774 from 840 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 8:
86 can be fit into 660 7 times, resulting in a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 5896.97
Subtract 602 from 660 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 9:
If we divide 580 by 86, we get 6 and a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 5896.976
The remainder is 64 after subtracting 516 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 10:
When dividing 640 by 86, we get 7 with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 5896.9767
The remainder is 38 after subtracting 602 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 11:
The number 86 fits into 380 4 times, leaving a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 5896.97674
The remainder is 36 after subtracting 344 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 12:
The number 86 fits into 360 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 5896.976744
The remainder is 16 after subtracting 344 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 5896.976744 with a remainder of 1.6e-06.
