71275491 ÷ 20 
Let's see how many times 20 fits into 71275491.

Going ahead to step 1:
7 divided by 20 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 20

Moving on to step 2:
The number 20 fits into 71 3 times, leaving a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 60 from 71 to get 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 20

Step 3:
20 can be fit into 112 5 times, resulting in a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Deduct 100 from 112 and we're left with 12.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 20

On to step 4:
If we divide 127 by 20, we get 6 and a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 356.0
Subtract 120 from 127 to get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 20

Going ahead to step 5:
20 goes into 75 3 times with a remainder of 15.
The next digit of our result is 3. 
Result so far: 3563.0
If we subtract 60 from 75, we get 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 20

Advancing to step 6:
The number 20 fits into 154 7 times, leaving a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 35637.0
Subtracting 140 from 154 leaves us with 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 20

Step 7:
When dividing 149 by 20, we get 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 356377.0
Subtract 140 from 149 to get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 20

Let's proceed to step 8:
20 can be fit into 91 4 times, resulting in a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 3563774.0
The remainder is 11 after subtracting 80 from 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
When dividing 110 by 20, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 3563774.5
If we take 100 away from 110, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 3563774.55
If we take 100 away from 100, 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.

Our division results in 3563774.55 with a remaining 0.0.
