Let's divide 17768821 by 791
We want to figure out the number of times 17768821 can be divided by 791.

Moving on to step 1:
The number 791 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 791

Going ahead to step 2:
791 can be fit into 17 0 times, resulting in a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Include the next digit (7) from the dividend after 17, then repeat: 177 / 791

On to step 3:
If we divide 177 by 791, we get 0 and a remainder of 177.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 177, we get 177.
Take the next digit (6) from the dividend and append it to 177, then repeat: 1776 / 791

On to step 4:
791 can be fit into 1776 2 times, resulting in a remainder of 194.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 194 after subtracting 1582 from 1776.
Take the next digit (8) from the dividend and append it to 194, then repeat: 1948 / 791

On to step 5:
When dividing 1948 by 791, we get 2 with a remainder of 366.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Subtracting 1582 from 1948 leaves us with 366.
Append the next digit (8) from the dividend to 366 and continue with: 3668 / 791

Step 6:
The number 791 fits into 3668 4 times, leaving a remainder of 504.
Record the quotient 4 as the next digit in the result. 
Result so far: 224.0
If we subtract 3164 from 3668, we get 504.
Append the next digit (2) from the dividend to 504 and continue with: 5042 / 791

Advancing to step 7:
791 can be fit into 5042 6 times, resulting in a remainder of 296.
Put 6 as the next digit of the answer. 
Result so far: 2246.0
Subtracting 4746 from 5042 leaves us with 296.
Bring next digit (1) of the dividend behind the 296 and repeat the process: 2961 / 791

Step 8:
791 goes into 2961 3 times with a remainder of 588.
Use 3 as the next digit of our solution. 
Result so far: 22463.0
Subtract 2373 from 2961 to get 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Moving on to step 9:
If we divide 5880 by 791, we get 7 and a remainder of 343.
Record the quotient 7 as the next digit in the result. 
Result so far: 22463.7
Subtracting 5537 from 5880 leaves us with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Let's proceed to step 10:
791 can be fit into 3430 4 times, resulting in a remainder of 266.
The next digit of our result is 4. 
Result so far: 22463.74
Subtract 3164 from 3430 to get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

On to step 11:
791 goes into 2660 3 times with a remainder of 287.
Record the quotient 3 as the next digit in the result. 
Result so far: 22463.743
Subtracting 2373 from 2660 leaves us with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Advancing to step 12:
The number 791 fits into 2870 3 times, leaving a remainder of 497.
Write down 3 as next digit of the result. 
Result so far: 22463.7433
If we take 2373 away from 2870, we end up with 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

The final result is 22463.7433 with a remainder of 0.00497.
