Let's divide 55271571 by 660
We want to divide 55271571 by 660.

Going ahead to step 1:
If we divide 5 by 660, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 660

Step 2:
660 goes into 55 0 times with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Grab the next digit (2) from the dividend, add it to 55, then carry on: 552 / 660

Advancing to step 3:
660 can be fit into 552 0 times, resulting in a remainder of 552.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 552 to get 552.
Append the next digit (7) from the dividend to 552 and continue with: 5527 / 660

Advancing to step 4:
660 goes into 5527 8 times with a remainder of 247.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 247 after subtracting 5280 from 5527.
Grab the next digit (1) from the dividend, add it to 247, then carry on: 2471 / 660

Going ahead to step 5:
660 goes into 2471 3 times with a remainder of 491.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
If we subtract 1980 from 2471, we get 491.
Fetch the next digit (5) from the dividend, attach it to 491 and continue: 4915 / 660

Going ahead to step 6:
The number 660 fits into 4915 7 times, leaving a remainder of 295.
Write down 7 as next digit of the result. 
Result so far: 837.0
If we take 4620 away from 4915, we end up with 295.
Take the next digit (7) from the dividend and append it to 295, then repeat: 2957 / 660

Step 7:
If we divide 2957 by 660, we get 4 and a remainder of 317.
The next digit of our result is 4. 
Result so far: 8374.0
Subtract 2640 from 2957 to get 317.
Fetch the next digit (1) from the dividend, attach it to 317 and continue: 3171 / 660

Let's proceed to step 8:
If we divide 3171 by 660, we get 4 and a remainder of 531.
Record the quotient 4 as the next digit in the result. 
Result so far: 83744.0
The remainder is 531 after subtracting 2640 from 3171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

On to step 9:
If we divide 5310 by 660, we get 8 and a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 83744.8
Deduct 5280 from 5310 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
660 can be fit into 300 0 times, resulting in a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 83744.8
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 11:
3000 divided by 660 is 4 with a remainder of 360.
The next digit of our result is 4. 
Result so far: 83744.804
Deduct 2640 from 3000 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 12:
3600 divided by 660 is 5 with a remainder of 300.
The next digit of our result is 5. 
Result so far: 83744.8045
Deduct 3300 from 3600 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 13:
660 goes into 3000 4 times with a remainder of 360.
Use 4 as the next digit of our solution. 
Result so far: 83744.80454
Subtracting 2640 from 3000 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 14:
3600 divided by 660 is 5 with a remainder of 300.
Put 5 as the next digit of the answer. 
Result so far: 83744.804545
The remainder is 300 after subtracting 3300 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 15:
3000 divided by 660 is 4 with a remainder of 360.
The next digit of our result is 4. 
Result so far: 83744.8045454
Deduct 2640 from 3000 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 16:
660 goes into 3600 5 times with a remainder of 300.
Put 5 as the next digit of the answer. 
Result so far: 83744.80454545
Deduct 3300 from 3600 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final result is 83744.80454545 with a remainder of 3e-07.
