We look at the division of 20640605 by 30 
Our goal is to divide 20640605 by 30.

Moving on to step 1:
The number 30 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 30

Moving on to step 2:
If we divide 20 by 30, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 30

On to step 3:
The number 30 fits into 206 6 times, leaving a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 180 from 206 to get 26.
Append the next digit (4) from the dividend to 26 and continue with: 264 / 30

On to step 4:
If we divide 264 by 30, we get 8 and a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 68.0
Subtract 240 from 264 to get 24.
Grab the next digit (0) from the dividend, add it to 24, then carry on: 240 / 30

Advancing to step 5:
If we divide 240 by 30, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 688.0
Subtract 240 from 240 to get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 30

Going ahead to step 6:
The number 30 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 6880.0
Subtract 0 from 6 to get 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 30

Step 7:
30 goes into 60 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 68802.0
Subtracting 60 from 60 leaves us with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 30

Advancing to step 8:
30 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 688020.0
Deduct 0 from 5 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
50 divided by 30 is 1 with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 688020.1
If we subtract 30 from 50, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
When dividing 200 by 30, we get 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 688020.16
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 688020.166
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 688020.166, with a leftover of 0.002.
