76712909 ÷ 424 
We want to figure out the number of times 76712909 can be divided by 424.

Step 1:
424 goes into 7 0 times with 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.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 424

On to step 2:
424 goes into 76 0 times with a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Fetch the next digit (7) from the dividend, attach it to 76 and continue: 767 / 424

Advancing to step 3:
424 goes into 767 1 times with a remainder of 343.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 424 from 767, we get 343.
Append the next digit (1) from the dividend to 343 and continue with: 3431 / 424

Moving on to step 4:
When dividing 3431 by 424, we get 8 with a remainder of 39.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 3392 from 3431 and we're left with 39.
Grab the next digit (2) from the dividend, add it to 39, then carry on: 392 / 424

Advancing to step 5:
392 divided by 424 is 0 with a remainder of 392.
The number 0 becomes the next digit in our result. 
Result so far: 180.0
If we subtract 0 from 392, we get 392.
Take the next digit (9) from the dividend and append it to 392, then repeat: 3929 / 424

Going ahead to step 6:
If we divide 3929 by 424, we get 9 and a remainder of 113.
Put 9 as the next digit of the answer. 
Result so far: 1809.0
Subtract 3816 from 3929 to get 113.
Append the next digit (0) from the dividend to 113 and continue with: 1130 / 424

Going ahead to step 7:
424 can be fit into 1130 2 times, resulting in a remainder of 282.
The next digit of our result is 2. 
Result so far: 18092.0
The remainder is 282 after subtracting 848 from 1130.
Grab the next digit (9) from the dividend, add it to 282, then carry on: 2829 / 424

Moving on to step 8:
2829 divided by 424 is 6 with a remainder of 285.
Write down 6 as next digit of the result. 
Result so far: 180926.0
If we subtract 2544 from 2829, we get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Advancing to step 9:
When dividing 2850 by 424, we get 6 with a remainder of 306.
Put 6 as the next digit of the answer. 
Result so far: 180926.6
Subtracting 2544 from 2850 leaves us 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.

Going ahead to step 10:
424 can be fit into 3060 7 times, resulting in a remainder of 92.
The number 7 becomes the next digit in our result. 
Result so far: 180926.67
If we take 2968 away from 3060, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 11:
920 divided by 424 is 2 with a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 180926.672
Subtract 848 from 920 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 12:
If we divide 720 by 424, we get 1 and a remainder of 296.
Use 1 as the next digit of our solution. 
Result so far: 180926.6721
The remainder is 296 after subtracting 424 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 13:
2960 divided by 424 is 6 with a remainder of 416.
Use 6 as the next digit of our solution. 
Result so far: 180926.67216
If we take 2544 away from 2960, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Step 14:
424 can be fit into 4160 9 times, resulting in a remainder of 344.
Put 9 as the next digit of the answer. 
Result so far: 180926.672169
Subtracting 3816 from 4160 leaves us with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Let's proceed to step 15:
424 goes into 3440 8 times with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 180926.6721698
Subtract 3392 from 3440 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 16:
480 divided by 424 is 1 with a remainder of 56.
Use 1 as the next digit of our solution. 
Result so far: 180926.67216981
If we subtract 424 from 480, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final result is 180926.67216981 with a remainder of 5.6e-08.
