21278745 ÷ 793 
Let's see how many times 793 fits into 21278745.

Going ahead to step 1:
When dividing 2 by 793, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 793

Step 2:
The number 793 fits into 21 0 times, leaving a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 793

Let's proceed to step 3:
793 goes into 212 0 times with a remainder of 212.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 212 after subtracting 0 from 212.
Append the next digit (7) from the dividend to 212 and continue with: 2127 / 793

Advancing to step 4:
793 can be fit into 2127 2 times, resulting in a remainder of 541.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 541 after subtracting 1586 from 2127.
Fetch the next digit (8) from the dividend, attach it to 541 and continue: 5418 / 793

Going ahead to step 5:
When dividing 5418 by 793, we get 6 with a remainder of 660.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Subtract 4758 from 5418 to get 660.
Grab the next digit (7) from the dividend, add it to 660, then carry on: 6607 / 793

Step 6:
If we divide 6607 by 793, we get 8 and a remainder of 263.
Put 8 as the next digit of the answer. 
Result so far: 268.0
If we take 6344 away from 6607, we end up with 263.
Take the next digit (4) from the dividend and append it to 263, then repeat: 2634 / 793

Moving on to step 7:
If we divide 2634 by 793, we get 3 and a remainder of 255.
The number 3 becomes the next digit in our result. 
Result so far: 2683.0
Deduct 2379 from 2634 and we're left with 255.
Fetch the next digit (5) from the dividend, attach it to 255 and continue: 2555 / 793

Let's proceed to step 8:
793 goes into 2555 3 times with a remainder of 176.
Write down 3 as next digit of the result. 
Result so far: 26833.0
Deduct 2379 from 2555 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 9:
793 goes into 1760 2 times with a remainder of 174.
The number 2 becomes the next digit in our result. 
Result so far: 26833.2
If we take 1586 away from 1760, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 10:
The number 793 fits into 1740 2 times, leaving a remainder of 154.
The number 2 becomes the next digit in our result. 
Result so far: 26833.22
If we subtract 1586 from 1740, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

The final result is 26833.22 with a remainder of 0.154.
