Let's divide 66221271 by 655
We want to figure out the number of times 66221271 can be divided by 655.

On to step 1:
If we divide 6 by 655, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 655

Step 2:
655 can be fit into 66 0 times, resulting in a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Bring next digit (2) of the dividend behind the 66 and repeat the process: 662 / 655

Going ahead to step 3:
662 divided by 655 is 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 655 from 662 to get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 655

Advancing to step 4:
The number 655 fits into 72 0 times, leaving a remainder of 72.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 72, we end up with 72.
Take the next digit (1) from the dividend and append it to 72, then repeat: 721 / 655

Let's proceed to step 5:
If we divide 721 by 655, we get 1 and a remainder of 66.
Write down 1 as next digit of the result. 
Result so far: 101.0
Subtract 655 from 721 to get 66.
Fetch the next digit (2) from the dividend, attach it to 66 and continue: 662 / 655

Let's proceed to step 6:
The number 655 fits into 662 1 times, leaving a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1011.0
The remainder is 7 after subtracting 655 from 662.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 655

On to step 7:
655 goes into 77 0 times with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 10110.0
Subtract 0 from 77 to get 77.
Bring next digit (1) of the dividend behind the 77 and repeat the process: 771 / 655

Moving on to step 8:
655 can be fit into 771 1 times, resulting in a remainder of 116.
The number 1 becomes the next digit in our result. 
Result so far: 101101.0
Deduct 655 from 771 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 9:
655 can be fit into 1160 1 times, resulting in a remainder of 505.
Use 1 as the next digit of our solution. 
Result so far: 101101.1
Deduct 655 from 1160 and we're left with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Going ahead to step 10:
655 goes into 5050 7 times with a remainder of 465.
The number 7 becomes the next digit in our result. 
Result so far: 101101.17
Subtract 4585 from 5050 to get 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

On to step 11:
If we divide 4650 by 655, we get 7 and a remainder of 65.
Put 7 as the next digit of the answer. 
Result so far: 101101.177
If we take 4585 away from 4650, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

After the division, we end up with 101101.177 and a remainder of 0.0065.
