30285915 ÷ 771 
We want to figure out the number of times 30285915 can be divided by 771.

Step 1:
771 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 771

Moving on to step 2:
The number 771 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Fetch the next digit (2) from the dividend, attach it to 30 and continue: 302 / 771

On to step 3:
If we divide 302 by 771, we get 0 and a remainder of 302.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 302 leaves us with 302.
Include the next digit (8) from the dividend after 302, then repeat: 3028 / 771

Step 4:
771 goes into 3028 3 times with a remainder of 715.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 2313 away from 3028, we end up with 715.
Take the next digit (5) from the dividend and append it to 715, then repeat: 7155 / 771

Moving on to step 5:
When dividing 7155 by 771, we get 9 with a remainder of 216.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
The remainder is 216 after subtracting 6939 from 7155.
Include the next digit (9) from the dividend after 216, then repeat: 2169 / 771

On to step 6:
When dividing 2169 by 771, we get 2 with a remainder of 627.
The next digit of our result is 2. 
Result so far: 392.0
The remainder is 627 after subtracting 1542 from 2169.
Grab the next digit (1) from the dividend, add it to 627, then carry on: 6271 / 771

Let's proceed to step 7:
If we divide 6271 by 771, we get 8 and a remainder of 103.
The number 8 becomes the next digit in our result. 
Result so far: 3928.0
If we subtract 6168 from 6271, we get 103.
Take the next digit (5) from the dividend and append it to 103, then repeat: 1035 / 771

Advancing to step 8:
771 can be fit into 1035 1 times, resulting in a remainder of 264.
Record the quotient 1 as the next digit in the result. 
Result so far: 39281.0
Subtracting 771 from 1035 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Step 9:
When dividing 2640 by 771, we get 3 with a remainder of 327.
The number 3 becomes the next digit in our result. 
Result so far: 39281.3
The remainder is 327 after subtracting 2313 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Going ahead to step 10:
When dividing 3270 by 771, we get 4 with a remainder of 186.
Record the quotient 4 as the next digit in the result. 
Result so far: 39281.34
The remainder is 186 after subtracting 3084 from 3270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 11:
1860 divided by 771 is 2 with a remainder of 318.
Put 2 as the next digit of the answer. 
Result so far: 39281.342
Subtracting 1542 from 1860 leaves us with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Step 12:
771 goes into 3180 4 times with a remainder of 96.
Write down 4 as next digit of the result. 
Result so far: 39281.3424
If we subtract 3084 from 3180, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 13:
960 divided by 771 is 1 with a remainder of 189.
Write down 1 as next digit of the result. 
Result so far: 39281.34241
Subtracting 771 from 960 leaves us with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Advancing to step 14:
771 goes into 1890 2 times with a remainder of 348.
Write down 2 as next digit of the result. 
Result so far: 39281.342412
If we take 1542 away from 1890, we end up with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 15:
If we divide 3480 by 771, we get 4 and a remainder of 396.
The next digit of our result is 4. 
Result so far: 39281.3424124
Subtracting 3084 from 3480 leaves us with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Moving on to step 16:
771 can be fit into 3960 5 times, resulting in a remainder of 105.
The number 5 becomes the next digit in our result. 
Result so far: 39281.34241245
If we subtract 3855 from 3960, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Our division results in 39281.34241245 with a remaining 1.05e-07.
