We look at the division of 66009567 by 20 
Let's see how many times 20 fits into 66009567.

Advancing to step 1:
20 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 20

Step 2:
20 goes into 66 3 times with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 6 after subtracting 60 from 66.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 20

On to step 3:
20 goes into 60 3 times with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
The remainder is 0 after subtracting 60 from 60.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 20

On to step 4:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 330.0
If we subtract 0 from 0, we get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 20

On to step 5:
20 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 3300.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 20

Advancing to step 6:
If we divide 95 by 20, we get 4 and a remainder of 15.
The next digit of our result is 4. 
Result so far: 33004.0
Subtracting 80 from 95 leaves us with 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 20

On to step 7:
If we divide 156 by 20, we get 7 and a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 330047.0
Deduct 140 from 156 and we're left with 16.
Bring next digit (7) of the dividend behind the 16 and repeat the process: 167 / 20

Step 8:
167 divided by 20 is 8 with a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 3300478.0
The remainder is 7 after subtracting 160 from 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 9:
20 can be fit into 70 3 times, resulting in a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 3300478.3
The remainder is 10 after subtracting 60 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
20 goes into 100 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 3300478.35
If we subtract 100 from 100, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 3300478.35
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 3300478.35
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 3300478.35, and the remainder is 0.0.
