Let's see how many times 617 fits into 66506049.

Going ahead to step 1:
The number 617 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 617

On to step 2:
When dividing 66 by 617, we get 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Append the next digit (5) from the dividend to 66 and continue with: 665 / 617

Step 3:
When dividing 665 by 617, we get 1 with a remainder of 48.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 617 from 665, we get 48.
Grab the next digit (0) from the dividend, add it to 48, then carry on: 480 / 617

On to step 4:
When dividing 480 by 617, we get 0 with a remainder of 480.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 480 and we're left with 480.
Append the next digit (6) from the dividend to 480 and continue with: 4806 / 617

Step 5:
If we divide 4806 by 617, we get 7 and a remainder of 487.
Put 7 as the next digit of the answer. 
Result so far: 107.0
Subtracting 4319 from 4806 leaves us with 487.
Include the next digit (0) from the dividend after 487, then repeat: 4870 / 617

Moving on to step 6:
The number 617 fits into 4870 7 times, leaving a remainder of 551.
Record the quotient 7 as the next digit in the result. 
Result so far: 1077.0
If we subtract 4319 from 4870, we get 551.
Append the next digit (4) from the dividend to 551 and continue with: 5514 / 617

Let's proceed to step 7:
5514 divided by 617 is 8 with a remainder of 578.
Record the quotient 8 as the next digit in the result. 
Result so far: 10778.0
Subtracting 4936 from 5514 leaves us with 578.
Fetch the next digit (9) from the dividend, attach it to 578 and continue: 5789 / 617

Let's proceed to step 8:
617 goes into 5789 9 times with a remainder of 236.
Write down 9 as next digit of the result. 
Result so far: 107789.0
Subtract 5553 from 5789 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Going ahead to step 9:
2360 divided by 617 is 3 with a remainder of 509.
Record the quotient 3 as the next digit in the result. 
Result so far: 107789.3
Subtracting 1851 from 2360 leaves us with 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Moving on to step 10:
The number 617 fits into 5090 8 times, leaving a remainder of 154.
The next digit of our result is 8. 
Result so far: 107789.38
Subtracting 4936 from 5090 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Going ahead to step 11:
When dividing 1540 by 617, we get 2 with a remainder of 306.
The number 2 becomes the next digit in our result. 
Result so far: 107789.382
Deduct 1234 from 1540 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Moving on to step 12:
If we divide 3060 by 617, we get 4 and a remainder of 592.
Record the quotient 4 as the next digit in the result. 
Result so far: 107789.3824
Subtracting 2468 from 3060 leaves us with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

On to step 13:
617 goes into 5920 9 times with a remainder of 367.
The next digit of our result is 9. 
Result so far: 107789.38249
Deduct 5553 from 5920 and we're left with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Going ahead to step 14:
The number 617 fits into 3670 5 times, leaving a remainder of 585.
Put 5 as the next digit of the answer. 
Result so far: 107789.382495
Subtract 3085 from 3670 to get 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Moving on to step 15:
617 goes into 5850 9 times with a remainder of 297.
Put 9 as the next digit of the answer. 
Result so far: 107789.3824959
If we subtract 5553 from 5850, we get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Going ahead to step 16:
If we divide 2970 by 617, we get 4 and a remainder of 502.
Put 4 as the next digit of the answer. 
Result so far: 107789.38249594
Deduct 2468 from 2970 and we're left with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

The final result is 107789.38249594 with a remainder of 5.02e-07.
