20497945 divided by 718 
Let's see how many times 718 fits into 20497945.

Going ahead to step 1:
When dividing 2 by 718, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 718

Let's proceed to step 2:
718 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 718

Moving on to step 3:
If we divide 204 by 718, we get 0 and a remainder of 204.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 204 leaves us with 204.
Append the next digit (9) from the dividend to 204 and continue with: 2049 / 718

Step 4:
718 can be fit into 2049 2 times, resulting in a remainder of 613.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1436 from 2049 leaves us with 613.
Append the next digit (7) from the dividend to 613 and continue with: 6137 / 718

On to step 5:
718 goes into 6137 8 times with a remainder of 393.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Deduct 5744 from 6137 and we're left with 393.
Take the next digit (9) from the dividend and append it to 393, then repeat: 3939 / 718

On to step 6:
718 can be fit into 3939 5 times, resulting in a remainder of 349.
The number 5 becomes the next digit in our result. 
Result so far: 285.0
The remainder is 349 after subtracting 3590 from 3939.
Fetch the next digit (4) from the dividend, attach it to 349 and continue: 3494 / 718

Step 7:
If we divide 3494 by 718, we get 4 and a remainder of 622.
Write down 4 as next digit of the result. 
Result so far: 2854.0
If we take 2872 away from 3494, we end up with 622.
Include the next digit (5) from the dividend after 622, then repeat: 6225 / 718

Going ahead to step 8:
When dividing 6225 by 718, we get 8 with a remainder of 481.
The number 8 becomes the next digit in our result. 
Result so far: 28548.0
If we take 5744 away from 6225, we end up with 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Moving on to step 9:
If we divide 4810 by 718, we get 6 and a remainder of 502.
Write down 6 as next digit of the result. 
Result so far: 28548.6
Deduct 4308 from 4810 and we're left with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Let's proceed to step 10:
When dividing 5020 by 718, we get 6 with a remainder of 712.
Record the quotient 6 as the next digit in the result. 
Result so far: 28548.66
Subtracting 4308 from 5020 leaves us with 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

In conclusion, the division gives 28548.66 with a balance of 0.712.
