86475009 ÷ 815 
Let's see how many times 815 fits into 86475009.

Let's proceed to step 1:
815 can be fit into 8 0 times, resulting in 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 / 815

Going ahead to step 2:
The number 815 fits into 86 0 times, leaving 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.
Include the next digit (4) from the dividend after 86, then repeat: 864 / 815

Going ahead to step 3:
815 goes into 864 1 times with a remainder of 49.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 815 from 864 to get 49.
Take the next digit (7) from the dividend and append it to 49, then repeat: 497 / 815

On to step 4:
The number 815 fits into 497 0 times, leaving a remainder of 497.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 497, we end up with 497.
Grab the next digit (5) from the dividend, add it to 497, then carry on: 4975 / 815

Advancing to step 5:
If we divide 4975 by 815, we get 6 and a remainder of 85.
Put 6 as the next digit of the answer. 
Result so far: 106.0
Subtracting 4890 from 4975 leaves us with 85.
Fetch the next digit (0) from the dividend, attach it to 85 and continue: 850 / 815

Step 6:
815 goes into 850 1 times with a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 1061.0
Subtracting 815 from 850 leaves us with 35.
Append the next digit (0) from the dividend to 35 and continue with: 350 / 815

Let's proceed to step 7:
815 goes into 350 0 times with a remainder of 350.
The number 0 becomes the next digit in our result. 
Result so far: 10610.0
The remainder is 350 after subtracting 0 from 350.
Append the next digit (9) from the dividend to 350 and continue with: 3509 / 815

Going ahead to step 8:
The number 815 fits into 3509 4 times, leaving a remainder of 249.
Put 4 as the next digit of the answer. 
Result so far: 106104.0
The remainder is 249 after subtracting 3260 from 3509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Advancing to step 9:
815 goes into 2490 3 times with a remainder of 45.
The next digit of our result is 3. 
Result so far: 106104.3
The remainder is 45 after subtracting 2445 from 2490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 10:
The number 815 fits into 450 0 times, leaving a remainder of 450.
Put 0 as the next digit of the answer. 
Result so far: 106104.3
Subtracting 0 from 450 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 11:
4500 divided by 815 is 5 with a remainder of 425.
Record the quotient 5 as the next digit in the result. 
Result so far: 106104.305
The remainder is 425 after subtracting 4075 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

On to step 12:
4250 divided by 815 is 5 with a remainder of 175.
Put 5 as the next digit of the answer. 
Result so far: 106104.3055
Subtracting 4075 from 4250 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Our division results in 106104.3055 with a remaining 0.00175.
