We're dividing 86087563 by 499 
We want to divide 86087563 by 499.

On to step 1:
8 divided by 499 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 499

Going ahead to step 2:
86 divided by 499 is 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Append the next digit (0) from the dividend to 86 and continue with: 860 / 499

Moving on to step 3:
860 divided by 499 is 1 with a remainder of 361.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 499 from 860 leaves us with 361.
Append the next digit (8) from the dividend to 361 and continue with: 3618 / 499

Let's proceed to step 4:
499 can be fit into 3618 7 times, resulting in a remainder of 125.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we subtract 3493 from 3618, we get 125.
Bring next digit (7) of the dividend behind the 125 and repeat the process: 1257 / 499

Advancing to step 5:
If we divide 1257 by 499, we get 2 and a remainder of 259.
The next digit of our result is 2. 
Result so far: 172.0
Deduct 998 from 1257 and we're left with 259.
Bring next digit (5) of the dividend behind the 259 and repeat the process: 2595 / 499

Going ahead to step 6:
499 can be fit into 2595 5 times, resulting in a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 1725.0
The remainder is 100 after subtracting 2495 from 2595.
Bring next digit (6) of the dividend behind the 100 and repeat the process: 1006 / 499

Let's proceed to step 7:
The number 499 fits into 1006 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 17252.0
The remainder is 8 after subtracting 998 from 1006.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 499

Going ahead to step 8:
83 divided by 499 is 0 with a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 172520.0
Subtract 0 from 83 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 9:
The number 499 fits into 830 1 times, leaving a remainder of 331.
The number 1 becomes the next digit in our result. 
Result so far: 172520.1
Deduct 499 from 830 and we're left with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Going ahead to step 10:
499 can be fit into 3310 6 times, resulting in a remainder of 316.
The number 6 becomes the next digit in our result. 
Result so far: 172520.16
Subtract 2994 from 3310 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 11:
499 can be fit into 3160 6 times, resulting in a remainder of 166.
Write down 6 as next digit of the result. 
Result so far: 172520.166
If we take 2994 away from 3160, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

After the division, we end up with 172520.166 and a remainder of 0.0166.
