We look at the division of 86418274 by 665 
We're looking to find how many times 665 goes into 86418274.

On to step 1:
665 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 665

Let's proceed to step 2:
The number 665 fits into 86 0 times, leaving a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Fetch the next digit (4) from the dividend, attach it to 86 and continue: 864 / 665

Moving on to step 3:
When dividing 864 by 665, we get 1 with a remainder of 199.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 665 from 864 to get 199.
Fetch the next digit (1) from the dividend, attach it to 199 and continue: 1991 / 665

Let's proceed to step 4:
665 goes into 1991 2 times with a remainder of 661.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 1330 from 1991, we get 661.
Append the next digit (8) from the dividend to 661 and continue with: 6618 / 665

Let's proceed to step 5:
If we divide 6618 by 665, we get 9 and a remainder of 633.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
If we subtract 5985 from 6618, we get 633.
Grab the next digit (2) from the dividend, add it to 633, then carry on: 6332 / 665

On to step 6:
The number 665 fits into 6332 9 times, leaving a remainder of 347.
Put 9 as the next digit of the answer. 
Result so far: 1299.0
Subtract 5985 from 6332 to get 347.
Bring next digit (7) of the dividend behind the 347 and repeat the process: 3477 / 665

Step 7:
665 goes into 3477 5 times with a remainder of 152.
Put 5 as the next digit of the answer. 
Result so far: 12995.0
If we take 3325 away from 3477, we end up with 152.
Include the next digit (4) from the dividend after 152, then repeat: 1524 / 665

On to step 8:
If we divide 1524 by 665, we get 2 and a remainder of 194.
Record the quotient 2 as the next digit in the result. 
Result so far: 129952.0
Subtract 1330 from 1524 to get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

On to step 9:
665 goes into 1940 2 times with a remainder of 610.
Use 2 as the next digit of our solution. 
Result so far: 129952.2
If we subtract 1330 from 1940, we get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

On to step 10:
665 goes into 6100 9 times with a remainder of 115.
Put 9 as the next digit of the answer. 
Result so far: 129952.29
If we subtract 5985 from 6100, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 11:
665 goes into 1150 1 times with a remainder of 485.
Record the quotient 1 as the next digit in the result. 
Result so far: 129952.291
Deduct 665 from 1150 and we're left with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Step 12:
If we divide 4850 by 665, we get 7 and a remainder of 195.
Use 7 as the next digit of our solution. 
Result so far: 129952.2917
If we take 4655 away from 4850, we end up with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Moving on to step 13:
If we divide 1950 by 665, we get 2 and a remainder of 620.
Write down 2 as next digit of the result. 
Result so far: 129952.29172
Subtracting 1330 from 1950 leaves us with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 14:
When dividing 6200 by 665, we get 9 with a remainder of 215.
Use 9 as the next digit of our solution. 
Result so far: 129952.291729
Subtracting 5985 from 6200 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Step 15:
2150 divided by 665 is 3 with a remainder of 155.
Record the quotient 3 as the next digit in the result. 
Result so far: 129952.2917293
If we subtract 1995 from 2150, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

On to step 16:
665 goes into 1550 2 times with a remainder of 220.
Write down 2 as next digit of the result. 
Result so far: 129952.29172932
Deduct 1330 from 1550 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

The final outcome is 129952.29172932, with a leftover of 2.2e-07.
