80518323 ÷ 424 
We want to divide 80518323 by 424.

On to step 1:
424 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 424

Advancing to step 2:
424 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Fetch the next digit (5) from the dividend, attach it to 80 and continue: 805 / 424

On to step 3:
805 divided by 424 is 1 with a remainder of 381.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 381 after subtracting 424 from 805.
Fetch the next digit (1) from the dividend, attach it to 381 and continue: 3811 / 424

Going ahead to step 4:
When dividing 3811 by 424, we get 8 with a remainder of 419.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 419 after subtracting 3392 from 3811.
Include the next digit (8) from the dividend after 419, then repeat: 4198 / 424

Let's proceed to step 5:
424 can be fit into 4198 9 times, resulting in a remainder of 382.
Write down 9 as next digit of the result. 
Result so far: 189.0
If we subtract 3816 from 4198, we get 382.
Append the next digit (3) from the dividend to 382 and continue with: 3823 / 424

On to step 6:
When dividing 3823 by 424, we get 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 1899.0
Subtract 3816 from 3823 to get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 424

On to step 7:
424 goes into 72 0 times with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 18990.0
If we subtract 0 from 72, we get 72.
Fetch the next digit (3) from the dividend, attach it to 72 and continue: 723 / 424

Step 8:
If we divide 723 by 424, we get 1 and a remainder of 299.
The next digit of our result is 1. 
Result so far: 189901.0
Subtracting 424 from 723 leaves us with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

On to step 9:
424 can be fit into 2990 7 times, resulting in a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 189901.7
Subtracting 2968 from 2990 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
424 can be fit into 220 0 times, resulting in a remainder of 220.
Write down 0 as next digit of the result. 
Result so far: 189901.7
Subtract 0 from 220 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 11:
The number 424 fits into 2200 5 times, leaving a remainder of 80.
Use 5 as the next digit of our solution. 
Result so far: 189901.705
Subtracting 2120 from 2200 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 12:
The number 424 fits into 800 1 times, leaving a remainder of 376.
Use 1 as the next digit of our solution. 
Result so far: 189901.7051
If we subtract 424 from 800, we get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Moving on to step 13:
424 goes into 3760 8 times with a remainder of 368.
The number 8 becomes the next digit in our result. 
Result so far: 189901.70518
Subtract 3392 from 3760 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 14:
The number 424 fits into 3680 8 times, leaving a remainder of 288.
The next digit of our result is 8. 
Result so far: 189901.705188
The remainder is 288 after subtracting 3392 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

In conclusion, the division gives 189901.705188 with a balance of 2.88e-05.
