80522472 divided by 424 
We want to figure out the number of times 80522472 can be divided by 424.

On to step 1:
If we divide 8 by 424, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 424

Moving on to step 2:
424 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Take the next digit (5) from the dividend and append it to 80, then repeat: 805 / 424

Moving on to step 3:
The number 424 fits into 805 1 times, leaving a remainder of 381.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 424 from 805 and we're left with 381.
Include the next digit (2) from the dividend after 381, then repeat: 3812 / 424

Moving on to step 4:
424 goes into 3812 8 times with a remainder of 420.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we subtract 3392 from 3812, we get 420.
Append the next digit (2) from the dividend to 420 and continue with: 4202 / 424

Step 5:
The number 424 fits into 4202 9 times, leaving a remainder of 386.
Write down 9 as next digit of the result. 
Result so far: 189.0
Subtract 3816 from 4202 to get 386.
Take the next digit (4) from the dividend and append it to 386, then repeat: 3864 / 424

Going ahead to step 6:
When dividing 3864 by 424, we get 9 with a remainder of 48.
Use 9 as the next digit of our solution. 
Result so far: 1899.0
If we take 3816 away from 3864, we end up with 48.
Append the next digit (7) from the dividend to 48 and continue with: 487 / 424

Advancing to step 7:
When dividing 487 by 424, we get 1 with a remainder of 63.
Use 1 as the next digit of our solution. 
Result so far: 18991.0
Subtract 424 from 487 to get 63.
Bring next digit (2) of the dividend behind the 63 and repeat the process: 632 / 424

Advancing to step 8:
424 can be fit into 632 1 times, resulting in a remainder of 208.
Write down 1 as next digit of the result. 
Result so far: 189911.0
Deduct 424 from 632 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 9:
424 can be fit into 2080 4 times, resulting in a remainder of 384.
Record the quotient 4 as the next digit in the result. 
Result so far: 189911.4
Subtracting 1696 from 2080 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 10:
3840 divided by 424 is 9 with a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 189911.49
The remainder is 24 after subtracting 3816 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
240 divided by 424 is 0 with a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 189911.49
Subtract 0 from 240 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 12:
The number 424 fits into 2400 5 times, leaving a remainder of 280.
Put 5 as the next digit of the answer. 
Result so far: 189911.4905
Deduct 2120 from 2400 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 13:
If we divide 2800 by 424, we get 6 and a remainder of 256.
Use 6 as the next digit of our solution. 
Result so far: 189911.49056
If we subtract 2544 from 2800, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 14:
424 goes into 2560 6 times with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 189911.490566
Subtracting 2544 from 2560 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 189911.490566, with a leftover of 1.6e-06.
