78308068 ÷ 524 
We want to figure out the number of times 78308068 can be divided by 524.

Advancing to step 1:
If we divide 7 by 524, we get 0 and 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.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 524

Step 2:
When dividing 78 by 524, we get 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Append the next digit (3) from the dividend to 78 and continue with: 783 / 524

Advancing to step 3:
783 divided by 524 is 1 with a remainder of 259.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 524 from 783 leaves us with 259.
Take the next digit (0) from the dividend and append it to 259, then repeat: 2590 / 524

Let's proceed to step 4:
524 goes into 2590 4 times with a remainder of 494.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Deduct 2096 from 2590 and we're left with 494.
Include the next digit (8) from the dividend after 494, then repeat: 4948 / 524

Advancing to step 5:
When dividing 4948 by 524, we get 9 with a remainder of 232.
Put 9 as the next digit of the answer. 
Result so far: 149.0
The remainder is 232 after subtracting 4716 from 4948.
Bring next digit (0) of the dividend behind the 232 and repeat the process: 2320 / 524

Moving on to step 6:
2320 divided by 524 is 4 with a remainder of 224.
Record the quotient 4 as the next digit in the result. 
Result so far: 1494.0
If we subtract 2096 from 2320, we get 224.
Include the next digit (6) from the dividend after 224, then repeat: 2246 / 524

Going ahead to step 7:
When dividing 2246 by 524, we get 4 with a remainder of 150.
Put 4 as the next digit of the answer. 
Result so far: 14944.0
Subtracting 2096 from 2246 leaves us with 150.
Grab the next digit (8) from the dividend, add it to 150, then carry on: 1508 / 524

On to step 8:
1508 divided by 524 is 2 with a remainder of 460.
Record the quotient 2 as the next digit in the result. 
Result so far: 149442.0
If we take 1048 away from 1508, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 9:
The number 524 fits into 4600 8 times, leaving a remainder of 408.
Use 8 as the next digit of our solution. 
Result so far: 149442.8
Deduct 4192 from 4600 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Going ahead to step 10:
When dividing 4080 by 524, we get 7 with a remainder of 412.
The number 7 becomes the next digit in our result. 
Result so far: 149442.87
Deduct 3668 from 4080 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Going ahead to step 11:
524 can be fit into 4120 7 times, resulting in a remainder of 452.
Put 7 as the next digit of the answer. 
Result so far: 149442.877
Subtracting 3668 from 4120 leaves us with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

The final outcome is 149442.877, with a leftover of 0.0452.
