We divide 17781677 by 815
We want to divide 17781677 by 815.

Going ahead to step 1:
815 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 815

Advancing to step 2:
815 can be fit into 17 0 times, resulting in a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 815

Step 3:
815 can be fit into 177 0 times, resulting in a remainder of 177.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 177 and we're left with 177.
Include the next digit (8) from the dividend after 177, then repeat: 1778 / 815

Let's proceed to step 4:
1778 divided by 815 is 2 with a remainder of 148.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1630 from 1778, we get 148.
Append the next digit (1) from the dividend to 148 and continue with: 1481 / 815

Step 5:
1481 divided by 815 is 1 with a remainder of 666.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we take 815 away from 1481, we end up with 666.
Append the next digit (6) from the dividend to 666 and continue with: 6666 / 815

Advancing to step 6:
815 can be fit into 6666 8 times, resulting in a remainder of 146.
The next digit of our result is 8. 
Result so far: 218.0
If we take 6520 away from 6666, we end up with 146.
Bring next digit (7) of the dividend behind the 146 and repeat the process: 1467 / 815

Let's proceed to step 7:
The number 815 fits into 1467 1 times, leaving a remainder of 652.
Use 1 as the next digit of our solution. 
Result so far: 2181.0
Subtract 815 from 1467 to get 652.
Take the next digit (7) from the dividend and append it to 652, then repeat: 6527 / 815

Let's proceed to step 8:
815 can be fit into 6527 8 times, resulting in a remainder of 7.
The next digit of our result is 8. 
Result so far: 21818.0
Deduct 6520 from 6527 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
815 goes into 70 0 times with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 21818.0
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
700 divided by 815 is 0 with a remainder of 700.
The next digit of our result is 0. 
Result so far: 21818.0
The remainder is 700 after subtracting 0 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The final result is 21818.0 with a remainder of 0.7.
