We're dividing 78593019 by 508 
We want to figure out the number of times 78593019 can be divided by 508.

On to step 1:
508 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 508

Going ahead to step 2:
When dividing 78 by 508, 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.
Include the next digit (5) from the dividend after 78, then repeat: 785 / 508

Let's proceed to step 3:
If we divide 785 by 508, we get 1 and a remainder of 277.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 508 away from 785, we end up with 277.
Append the next digit (9) from the dividend to 277 and continue with: 2779 / 508

Going ahead to step 4:
508 goes into 2779 5 times with a remainder of 239.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 2540 away from 2779, we end up with 239.
Take the next digit (3) from the dividend and append it to 239, then repeat: 2393 / 508

Let's proceed to step 5:
508 can be fit into 2393 4 times, resulting in a remainder of 361.
The next digit of our result is 4. 
Result so far: 154.0
Deduct 2032 from 2393 and we're left with 361.
Fetch the next digit (0) from the dividend, attach it to 361 and continue: 3610 / 508

Let's proceed to step 6:
When dividing 3610 by 508, we get 7 with a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 1547.0
If we take 3556 away from 3610, we end up with 54.
Bring next digit (1) of the dividend behind the 54 and repeat the process: 541 / 508

Step 7:
541 divided by 508 is 1 with a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 15471.0
Subtracting 508 from 541 leaves us with 33.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 508

Going ahead to step 8:
When dividing 339 by 508, we get 0 with a remainder of 339.
The next digit of our result is 0. 
Result so far: 154710.0
If we take 0 away from 339, we end up with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Going ahead to step 9:
The number 508 fits into 3390 6 times, leaving a remainder of 342.
Put 6 as the next digit of the answer. 
Result so far: 154710.6
Subtracting 3048 from 3390 leaves us with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 10:
508 goes into 3420 6 times with a remainder of 372.
Put 6 as the next digit of the answer. 
Result so far: 154710.66
The remainder is 372 after subtracting 3048 from 3420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

The final outcome is 154710.66, with a leftover of 0.372.
