78400535 ÷ 424 
Let's see how many times 424 fits into 78400535.

Let's proceed to step 1:
424 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 424

Let's proceed to step 2:
When dividing 78 by 424, we get 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Fetch the next digit (4) from the dividend, attach it to 78 and continue: 784 / 424

Step 3:
If we divide 784 by 424, we get 1 and a remainder of 360.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 424 from 784 to get 360.
Take the next digit (0) from the dividend and append it to 360, then repeat: 3600 / 424

On to step 4:
The number 424 fits into 3600 8 times, leaving a remainder of 208.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtracting 3392 from 3600 leaves us with 208.
Include the next digit (0) from the dividend after 208, then repeat: 2080 / 424

Going ahead to step 5:
The number 424 fits into 2080 4 times, leaving a remainder of 384.
The number 4 becomes the next digit in our result. 
Result so far: 184.0
Subtract 1696 from 2080 to get 384.
Bring next digit (5) of the dividend behind the 384 and repeat the process: 3845 / 424

Step 6:
The number 424 fits into 3845 9 times, leaving a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 1849.0
If we subtract 3816 from 3845, we get 29.
Grab the next digit (3) from the dividend, add it to 29, then carry on: 293 / 424

Let's proceed to step 7:
424 goes into 293 0 times with a remainder of 293.
The number 0 becomes the next digit in our result. 
Result so far: 18490.0
Subtract 0 from 293 to get 293.
Take the next digit (5) from the dividend and append it to 293, then repeat: 2935 / 424

Let's proceed to step 8:
When dividing 2935 by 424, we get 6 with a remainder of 391.
Put 6 as the next digit of the answer. 
Result so far: 184906.0
The remainder is 391 after subtracting 2544 from 2935.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Advancing to step 9:
424 goes into 3910 9 times with a remainder of 94.
The number 9 becomes the next digit in our result. 
Result so far: 184906.9
The remainder is 94 after subtracting 3816 from 3910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 10:
When dividing 940 by 424, we get 2 with a remainder of 92.
Write down 2 as next digit of the result. 
Result so far: 184906.92
Subtract 848 from 940 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 11:
424 can be fit into 920 2 times, resulting in a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 184906.922
If we subtract 848 from 920, we 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.

In conclusion, the division gives 184906.922 with a balance of 0.0072.
