We're dividing 86259711 by 665 
We want to figure out the number of times 86259711 can be divided by 665.

Moving on to step 1:
8 divided by 665 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 665

Let's proceed to step 2:
If we divide 86 by 665, we get 0 and a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Fetch the next digit (2) from the dividend, attach it to 86 and continue: 862 / 665

Step 3:
862 divided by 665 is 1 with a remainder of 197.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 197 after subtracting 665 from 862.
Take the next digit (5) from the dividend and append it to 197, then repeat: 1975 / 665

Moving on to step 4:
665 goes into 1975 2 times with a remainder of 645.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 1330 from 1975 and we're left with 645.
Take the next digit (9) from the dividend and append it to 645, then repeat: 6459 / 665

Going ahead to step 5:
665 can be fit into 6459 9 times, resulting in a remainder of 474.
The next digit of our result is 9. 
Result so far: 129.0
Subtract 5985 from 6459 to get 474.
Grab the next digit (7) from the dividend, add it to 474, then carry on: 4747 / 665

Moving on to step 6:
When dividing 4747 by 665, we get 7 with a remainder of 92.
The next digit of our result is 7. 
Result so far: 1297.0
Subtract 4655 from 4747 to get 92.
Bring next digit (1) of the dividend behind the 92 and repeat the process: 921 / 665

Let's proceed to step 7:
921 divided by 665 is 1 with a remainder of 256.
Record the quotient 1 as the next digit in the result. 
Result so far: 12971.0
Deduct 665 from 921 and we're left with 256.
Take the next digit (1) from the dividend and append it to 256, then repeat: 2561 / 665

Let's proceed to step 8:
If we divide 2561 by 665, we get 3 and a remainder of 566.
The next digit of our result is 3. 
Result so far: 129713.0
If we take 1995 away from 2561, we end up with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Going ahead to step 9:
665 goes into 5660 8 times with a remainder of 340.
Record the quotient 8 as the next digit in the result. 
Result so far: 129713.8
Subtract 5320 from 5660 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 10:
If we divide 3400 by 665, we get 5 and a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 129713.85
If we subtract 3325 from 3400, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 11:
If we divide 750 by 665, we get 1 and a remainder of 85.
Write down 1 as next digit of the result. 
Result so far: 129713.851
Deduct 665 from 750 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 12:
When dividing 850 by 665, we get 1 with a remainder of 185.
The next digit of our result is 1. 
Result so far: 129713.8511
Subtracting 665 from 850 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

The final outcome is 129713.8511, with a leftover of 0.00185.
