We look at the division of 87139863 by 495 
We're looking to find how many times 495 goes into 87139863.

Advancing to step 1:
When dividing 8 by 495, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 495

On to step 2:
The number 495 fits into 87 0 times, leaving a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Take the next digit (1) from the dividend and append it to 87, then repeat: 871 / 495

Going ahead to step 3:
The number 495 fits into 871 1 times, leaving a remainder of 376.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 495 away from 871, we end up with 376.
Bring next digit (3) of the dividend behind the 376 and repeat the process: 3763 / 495

On to step 4:
When dividing 3763 by 495, we get 7 with a remainder of 298.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Deduct 3465 from 3763 and we're left with 298.
Take the next digit (9) from the dividend and append it to 298, then repeat: 2989 / 495

Moving on to step 5:
2989 divided by 495 is 6 with a remainder of 19.
Write down 6 as next digit of the result. 
Result so far: 176.0
Subtracting 2970 from 2989 leaves us with 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 495

Advancing to step 6:
495 goes into 198 0 times with a remainder of 198.
The number 0 becomes the next digit in our result. 
Result so far: 1760.0
The remainder is 198 after subtracting 0 from 198.
Fetch the next digit (6) from the dividend, attach it to 198 and continue: 1986 / 495

On to step 7:
The number 495 fits into 1986 4 times, leaving a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 17604.0
Subtracting 1980 from 1986 leaves us with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 495

Moving on to step 8:
If we divide 63 by 495, we get 0 and a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 176040.0
If we subtract 0 from 63, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 9:
If we divide 630 by 495, we get 1 and a remainder of 135.
Use 1 as the next digit of our solution. 
Result so far: 176040.1
If we take 495 away from 630, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 10:
The number 495 fits into 1350 2 times, leaving a remainder of 360.
Use 2 as the next digit of our solution. 
Result so far: 176040.12
The remainder is 360 after subtracting 990 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 11:
495 goes into 3600 7 times with a remainder of 135.
Put 7 as the next digit of the answer. 
Result so far: 176040.127
Subtract 3465 from 3600 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 12:
495 can be fit into 1350 2 times, resulting in a remainder of 360.
The number 2 becomes the next digit in our result. 
Result so far: 176040.1272
The remainder is 360 after subtracting 990 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 13:
495 goes into 3600 7 times with a remainder of 135.
Record the quotient 7 as the next digit in the result. 
Result so far: 176040.12727
Subtracting 3465 from 3600 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 14:
If we divide 1350 by 495, we get 2 and a remainder of 360.
The next digit of our result is 2. 
Result so far: 176040.127272
If we take 990 away from 1350, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 15:
The number 495 fits into 3600 7 times, leaving a remainder of 135.
The next digit of our result is 7. 
Result so far: 176040.1272727
If we subtract 3465 from 3600, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 16:
The number 495 fits into 1350 2 times, leaving a remainder of 360.
Put 2 as the next digit of the answer. 
Result so far: 176040.12727272
If we take 990 away from 1350, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The final result is 176040.12727272 with a remainder of 3.6e-07.
