We look at the division of 66202730 by 387 
We want to figure out the number of times 66202730 can be divided by 387.

On to step 1:
When dividing 6 by 387, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 387

Let's proceed to step 2:
66 divided by 387 is 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Append the next digit (2) from the dividend to 66 and continue with: 662 / 387

Advancing to step 3:
The number 387 fits into 662 1 times, leaving a remainder of 275.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 387 away from 662, we end up with 275.
Include the next digit (0) from the dividend after 275, then repeat: 2750 / 387

On to step 4:
387 goes into 2750 7 times with a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 2709 from 2750, we get 41.
Grab the next digit (2) from the dividend, add it to 41, then carry on: 412 / 387

On to step 5:
The number 387 fits into 412 1 times, leaving a remainder of 25.
The next digit of our result is 1. 
Result so far: 171.0
The remainder is 25 after subtracting 387 from 412.
Take the next digit (7) from the dividend and append it to 25, then repeat: 257 / 387

Step 6:
387 can be fit into 257 0 times, resulting in a remainder of 257.
Put 0 as the next digit of the answer. 
Result so far: 1710.0
Subtract 0 from 257 to get 257.
Append the next digit (3) from the dividend to 257 and continue with: 2573 / 387

Moving on to step 7:
387 goes into 2573 6 times with a remainder of 251.
Use 6 as the next digit of our solution. 
Result so far: 17106.0
The remainder is 251 after subtracting 2322 from 2573.
Include the next digit (0) from the dividend after 251, then repeat: 2510 / 387

Advancing to step 8:
387 goes into 2510 6 times with a remainder of 188.
Write down 6 as next digit of the result. 
Result so far: 171066.0
Subtract 2322 from 2510 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Step 9:
387 can be fit into 1880 4 times, resulting in a remainder of 332.
The number 4 becomes the next digit in our result. 
Result so far: 171066.4
The remainder is 332 after subtracting 1548 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Step 10:
3320 divided by 387 is 8 with a remainder of 224.
Record the quotient 8 as the next digit in the result. 
Result so far: 171066.48
Subtracting 3096 from 3320 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 11:
The number 387 fits into 2240 5 times, leaving a remainder of 305.
Write down 5 as next digit of the result. 
Result so far: 171066.485
If we take 1935 away from 2240, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Step 12:
387 goes into 3050 7 times with a remainder of 341.
Write down 7 as next digit of the result. 
Result so far: 171066.4857
Deduct 2709 from 3050 and we're left with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

On to step 13:
The number 387 fits into 3410 8 times, leaving a remainder of 314.
Write down 8 as next digit of the result. 
Result so far: 171066.48578
Subtract 3096 from 3410 to get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Going ahead to step 14:
If we divide 3140 by 387, we get 8 and a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 171066.485788
Deduct 3096 from 3140 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 outcome is 171066.485788, with a leftover of 4.4e-06.
