81675591 divided by 815 
We're looking to find how many times 815 goes into 81675591.

Moving on 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.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 815

Step 2:
The number 815 fits into 81 0 times, leaving a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Grab the next digit (6) from the dividend, add it to 81, then carry on: 816 / 815

Let's proceed to step 3:
816 divided by 815 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 1 after subtracting 815 from 816.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 815

Going ahead to step 4:
815 goes into 17 0 times with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 17 to get 17.
Bring next digit (5) of the dividend behind the 17 and repeat the process: 175 / 815

Let's proceed to step 5:
175 divided by 815 is 0 with a remainder of 175.
Put 0 as the next digit of the answer. 
Result so far: 100.0
The remainder is 175 after subtracting 0 from 175.
Bring next digit (5) of the dividend behind the 175 and repeat the process: 1755 / 815

Moving on to step 6:
815 goes into 1755 2 times with a remainder of 125.
Write down 2 as next digit of the result. 
Result so far: 1002.0
If we subtract 1630 from 1755, we get 125.
Bring next digit (9) of the dividend behind the 125 and repeat the process: 1259 / 815

Going ahead to step 7:
When dividing 1259 by 815, we get 1 with a remainder of 444.
Use 1 as the next digit of our solution. 
Result so far: 10021.0
Deduct 815 from 1259 and we're left with 444.
Grab the next digit (1) from the dividend, add it to 444, then carry on: 4441 / 815

Let's proceed to step 8:
815 can be fit into 4441 5 times, resulting in a remainder of 366.
Put 5 as the next digit of the answer. 
Result so far: 100215.0
The remainder is 366 after subtracting 4075 from 4441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Let's proceed to step 9:
If we divide 3660 by 815, we get 4 and a remainder of 400.
Use 4 as the next digit of our solution. 
Result so far: 100215.4
Subtract 3260 from 3660 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 10:
815 can be fit into 4000 4 times, resulting in a remainder of 740.
The next digit of our result is 4. 
Result so far: 100215.44
If we take 3260 away from 4000, we end up with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

The quotient of the division is 100215.44, and the remainder is 0.74.
