We're dividing 81742790 by 815 
We're looking to find how many times 815 goes into 81742790.

Step 1:
The number 815 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 815

Let's proceed to step 2:
When dividing 81 by 815, we get 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Take the next digit (7) from the dividend and append it to 81, then repeat: 817 / 815

Moving on to step 3:
817 divided by 815 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 815 from 817 to get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 815

Moving on to step 4:
815 goes into 24 0 times with a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 24, we get 24.
Append the next digit (2) from the dividend to 24 and continue with: 242 / 815

Let's proceed to step 5:
If we divide 242 by 815, we get 0 and a remainder of 242.
Put 0 as the next digit of the answer. 
Result so far: 100.0
If we subtract 0 from 242, we get 242.
Take the next digit (7) from the dividend and append it to 242, then repeat: 2427 / 815

Moving on to step 6:
The number 815 fits into 2427 2 times, leaving a remainder of 797.
Write down 2 as next digit of the result. 
Result so far: 1002.0
The remainder is 797 after subtracting 1630 from 2427.
Append the next digit (9) from the dividend to 797 and continue with: 7979 / 815

Step 7:
7979 divided by 815 is 9 with a remainder of 644.
Use 9 as the next digit of our solution. 
Result so far: 10029.0
If we subtract 7335 from 7979, we get 644.
Bring next digit (0) of the dividend behind the 644 and repeat the process: 6440 / 815

Going ahead to step 8:
815 can be fit into 6440 7 times, resulting in a remainder of 735.
The number 7 becomes the next digit in our result. 
Result so far: 100297.0
Subtract 5705 from 6440 to get 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Step 9:
815 goes into 7350 9 times with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 100297.9
If we take 7335 away from 7350, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
When dividing 150 by 815, we get 0 with a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 100297.9
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 11:
815 goes into 1500 1 times with a remainder of 685.
Write down 1 as next digit of the result. 
Result so far: 100297.901
Subtracting 815 from 1500 leaves us with 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

On to step 12:
If we divide 6850 by 815, we get 8 and a remainder of 330.
Use 8 as the next digit of our solution. 
Result so far: 100297.9018
If we take 6520 away from 6850, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 13:
The number 815 fits into 3300 4 times, leaving a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 100297.90184
Subtract 3260 from 3300 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
815 can be fit into 400 0 times, resulting in a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 100297.90184
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 15:
The number 815 fits into 4000 4 times, leaving a remainder of 740.
Use 4 as the next digit of our solution. 
Result so far: 100297.9018404
Subtract 3260 from 4000 to get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Let's proceed to step 16:
815 can be fit into 7400 9 times, resulting in a remainder of 65.
Use 9 as the next digit of our solution. 
Result so far: 100297.90184049
Deduct 7335 from 7400 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The quotient of the division is 100297.90184049, and the remainder is 6.5e-08.
