17118389 ÷ 793 
Our goal is to divide 17118389 by 793.

Step 1:
793 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 793

Advancing to step 2:
When dividing 17 by 793, we get 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 793

On to step 3:
793 can be fit into 171 0 times, resulting in a remainder of 171.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 171 after subtracting 0 from 171.
Take the next digit (1) from the dividend and append it to 171, then repeat: 1711 / 793

Advancing to step 4:
793 can be fit into 1711 2 times, resulting in a remainder of 125.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 1586 away from 1711, we end up with 125.
Append the next digit (8) from the dividend to 125 and continue with: 1258 / 793

On to step 5:
When dividing 1258 by 793, we get 1 with a remainder of 465.
The next digit of our result is 1. 
Result so far: 21.0
Deduct 793 from 1258 and we're left with 465.
Take the next digit (3) from the dividend and append it to 465, then repeat: 4653 / 793

Step 6:
793 goes into 4653 5 times with a remainder of 688.
Use 5 as the next digit of our solution. 
Result so far: 215.0
Subtracting 3965 from 4653 leaves us with 688.
Append the next digit (8) from the dividend to 688 and continue with: 6888 / 793

Let's proceed to step 7:
6888 divided by 793 is 8 with a remainder of 544.
Record the quotient 8 as the next digit in the result. 
Result so far: 2158.0
If we take 6344 away from 6888, we end up with 544.
Grab the next digit (9) from the dividend, add it to 544, then carry on: 5449 / 793

Step 8:
The number 793 fits into 5449 6 times, leaving a remainder of 691.
Record the quotient 6 as the next digit in the result. 
Result so far: 21586.0
Subtract 4758 from 5449 to get 691.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6910, and continue the process.

Step 9:
When dividing 6910 by 793, we get 8 with a remainder of 566.
The next digit of our result is 8. 
Result so far: 21586.8
Subtracting 6344 from 6910 leaves us with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Let's proceed to step 10:
When dividing 5660 by 793, we get 7 with a remainder of 109.
Write down 7 as next digit of the result. 
Result so far: 21586.87
The remainder is 109 after subtracting 5551 from 5660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Moving on to step 11:
When dividing 1090 by 793, we get 1 with a remainder of 297.
Record the quotient 1 as the next digit in the result. 
Result so far: 21586.871
If we subtract 793 from 1090, we get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Advancing to step 12:
793 can be fit into 2970 3 times, resulting in a remainder of 591.
The next digit of our result is 3. 
Result so far: 21586.8713
If we take 2379 away from 2970, we end up with 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

Let's proceed to step 13:
793 goes into 5910 7 times with a remainder of 359.
Write down 7 as next digit of the result. 
Result so far: 21586.87137
Deduct 5551 from 5910 and we're left with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Let's proceed to step 14:
3590 divided by 793 is 4 with a remainder of 418.
Put 4 as the next digit of the answer. 
Result so far: 21586.871374
Subtracting 3172 from 3590 leaves us with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Advancing to step 15:
793 can be fit into 4180 5 times, resulting in a remainder of 215.
Write down 5 as next digit of the result. 
Result so far: 21586.8713745
If we take 3965 away from 4180, we end up with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Let's proceed to step 16:
The number 793 fits into 2150 2 times, leaving a remainder of 564.
The number 2 becomes the next digit in our result. 
Result so far: 21586.87137452
If we take 1586 away from 2150, we end up with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

The final outcome is 21586.87137452, with a leftover of 5.64e-07.
