We divide 77429934 by 309
We want to figure out the number of times 77429934 can be divided by 309.

Step 1:
309 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 309

Advancing to step 2:
309 goes into 77 0 times with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Bring next digit (4) of the dividend behind the 77 and repeat the process: 774 / 309

Moving on to step 3:
If we divide 774 by 309, we get 2 and a remainder of 156.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 618 away from 774, we end up with 156.
Append the next digit (2) from the dividend to 156 and continue with: 1562 / 309

Advancing to step 4:
309 goes into 1562 5 times with a remainder of 17.
The next digit of our result is 5. 
Result so far: 25.0
If we subtract 1545 from 1562, we get 17.
Take the next digit (9) from the dividend and append it to 17, then repeat: 179 / 309

On to step 5:
The number 309 fits into 179 0 times, leaving a remainder of 179.
Use 0 as the next digit of our solution. 
Result so far: 250.0
Deduct 0 from 179 and we're left with 179.
Include the next digit (9) from the dividend after 179, then repeat: 1799 / 309

Going ahead to step 6:
309 goes into 1799 5 times with a remainder of 254.
The next digit of our result is 5. 
Result so far: 2505.0
The remainder is 254 after subtracting 1545 from 1799.
Append the next digit (3) from the dividend to 254 and continue with: 2543 / 309

Moving on to step 7:
309 goes into 2543 8 times with a remainder of 71.
Write down 8 as next digit of the result. 
Result so far: 25058.0
Subtract 2472 from 2543 to get 71.
Take the next digit (4) from the dividend and append it to 71, then repeat: 714 / 309

Let's proceed to step 8:
If we divide 714 by 309, we get 2 and a remainder of 96.
Record the quotient 2 as the next digit in the result. 
Result so far: 250582.0
Deduct 618 from 714 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 9:
309 goes into 960 3 times with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 250582.3
If we take 927 away from 960, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 10:
309 goes into 330 1 times with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 250582.31
The remainder is 21 after subtracting 309 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 11:
The number 309 fits into 210 0 times, leaving a remainder of 210.
Put 0 as the next digit of the answer. 
Result so far: 250582.31
Subtract 0 from 210 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 12:
309 can be fit into 2100 6 times, resulting in a remainder of 246.
Write down 6 as next digit of the result. 
Result so far: 250582.3106
If we take 1854 away from 2100, we end up with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Let's proceed to step 13:
If we divide 2460 by 309, we get 7 and a remainder of 297.
Put 7 as the next digit of the answer. 
Result so far: 250582.31067
The remainder is 297 after subtracting 2163 from 2460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Step 14:
309 goes into 2970 9 times with a remainder of 189.
Record the quotient 9 as the next digit in the result. 
Result so far: 250582.310679
If we subtract 2781 from 2970, we get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Step 15:
309 goes into 1890 6 times with a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 250582.3106796
Subtract 1854 from 1890 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 16:
309 can be fit into 360 1 times, resulting in a remainder of 51.
The next digit of our result is 1. 
Result so far: 250582.31067961
If we subtract 309 from 360, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

After the division, we end up with 250582.31067961 and a remainder of 5.1e-08.
