30915470 ÷ 424 
We want to figure out the number of times 30915470 can be divided by 424.

Advancing to step 1:
3 divided by 424 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 424

Moving on to step 2:
The number 424 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 424

On to step 3:
424 can be fit into 309 0 times, resulting in a remainder of 309.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 309, we get 309.
Take the next digit (1) from the dividend and append it to 309, then repeat: 3091 / 424

Step 4:
The number 424 fits into 3091 7 times, leaving a remainder of 123.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 2968 from 3091 and we're left with 123.
Bring next digit (5) of the dividend behind the 123 and repeat the process: 1235 / 424

Moving on to step 5:
If we divide 1235 by 424, we get 2 and a remainder of 387.
Write down 2 as next digit of the result. 
Result so far: 72.0
If we subtract 848 from 1235, we get 387.
Grab the next digit (4) from the dividend, add it to 387, then carry on: 3874 / 424

Going ahead to step 6:
If we divide 3874 by 424, we get 9 and a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 729.0
If we subtract 3816 from 3874, we get 58.
Bring next digit (7) of the dividend behind the 58 and repeat the process: 587 / 424

Step 7:
424 can be fit into 587 1 times, resulting in a remainder of 163.
The next digit of our result is 1. 
Result so far: 7291.0
Subtracting 424 from 587 leaves us with 163.
Bring next digit (0) of the dividend behind the 163 and repeat the process: 1630 / 424

Step 8:
424 can be fit into 1630 3 times, resulting in a remainder of 358.
Record the quotient 3 as the next digit in the result. 
Result so far: 72913.0
Subtract 1272 from 1630 to get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Going ahead to step 9:
If we divide 3580 by 424, we get 8 and a remainder of 188.
The next digit of our result is 8. 
Result so far: 72913.8
If we take 3392 away from 3580, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 10:
1880 divided by 424 is 4 with a remainder of 184.
Use 4 as the next digit of our solution. 
Result so far: 72913.84
Subtracting 1696 from 1880 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 11:
424 can be fit into 1840 4 times, resulting in a remainder of 144.
Put 4 as the next digit of the answer. 
Result so far: 72913.844
If we subtract 1696 from 1840, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

In conclusion, the division gives 72913.844 with a balance of 0.0144.
