We're dividing 66005652 by 391 
We're looking to find how many times 391 goes into 66005652.

On to step 1:
If we divide 6 by 391, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 391

Step 2:
391 can be fit into 66 0 times, resulting in a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Append the next digit (0) from the dividend to 66 and continue with: 660 / 391

Moving on to step 3:
660 divided by 391 is 1 with a remainder of 269.
The next digit of our result is 1. 
Result so far: 1.0
If we take 391 away from 660, we end up with 269.
Bring next digit (0) of the dividend behind the 269 and repeat the process: 2690 / 391

On to step 4:
If we divide 2690 by 391, we get 6 and a remainder of 344.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we subtract 2346 from 2690, we get 344.
Append the next digit (5) from the dividend to 344 and continue with: 3445 / 391

Step 5:
391 can be fit into 3445 8 times, resulting in a remainder of 317.
Use 8 as the next digit of our solution. 
Result so far: 168.0
If we subtract 3128 from 3445, we get 317.
Grab the next digit (6) from the dividend, add it to 317, then carry on: 3176 / 391

Let's proceed to step 6:
If we divide 3176 by 391, we get 8 and a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 1688.0
Deduct 3128 from 3176 and we're left with 48.
Append the next digit (5) from the dividend to 48 and continue with: 485 / 391

Going ahead to step 7:
485 divided by 391 is 1 with a remainder of 94.
Record the quotient 1 as the next digit in the result. 
Result so far: 16881.0
Subtracting 391 from 485 leaves us with 94.
Append the next digit (2) from the dividend to 94 and continue with: 942 / 391

Going ahead to step 8:
The number 391 fits into 942 2 times, leaving a remainder of 160.
The number 2 becomes the next digit in our result. 
Result so far: 168812.0
Deduct 782 from 942 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 9:
If we divide 1600 by 391, we get 4 and a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 168812.4
Deduct 1564 from 1600 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 10:
The number 391 fits into 360 0 times, leaving a remainder of 360.
The next digit of our result is 0. 
Result so far: 168812.4
Subtracting 0 from 360 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.

Going ahead to step 11:
When dividing 3600 by 391, we get 9 with a remainder of 81.
Write down 9 as next digit of the result. 
Result so far: 168812.409
If we subtract 3519 from 3600, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 12:
391 goes into 810 2 times with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 168812.4092
Deduct 782 from 810 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 13:
391 can be fit into 280 0 times, resulting in a remainder of 280.
The number 0 becomes the next digit in our result. 
Result so far: 168812.4092
If we take 0 away from 280, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 14:
391 goes into 2800 7 times with a remainder of 63.
Put 7 as the next digit of the answer. 
Result so far: 168812.409207
Subtracting 2737 from 2800 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 15:
391 goes into 630 1 times with a remainder of 239.
The next digit of our result is 1. 
Result so far: 168812.4092071
Deduct 391 from 630 and we're left with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Let's proceed to step 16:
2390 divided by 391 is 6 with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 168812.40920716
Deduct 2346 from 2390 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 168812.40920716 with a remainder of 4.4e-08.
