78639378 divided by 593 
We want to figure out the number of times 78639378 can be divided by 593.

Step 1:
If we divide 7 by 593, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 593

On to step 2:
593 goes into 78 0 times with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Bring next digit (6) of the dividend behind the 78 and repeat the process: 786 / 593

Let's proceed to step 3:
When dividing 786 by 593, we get 1 with a remainder of 193.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 593 from 786 to get 193.
Include the next digit (3) from the dividend after 193, then repeat: 1933 / 593

Advancing to step 4:
593 can be fit into 1933 3 times, resulting in a remainder of 154.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 1779 from 1933 and we're left with 154.
Grab the next digit (9) from the dividend, add it to 154, then carry on: 1549 / 593

Let's proceed to step 5:
1549 divided by 593 is 2 with a remainder of 363.
Put 2 as the next digit of the answer. 
Result so far: 132.0
Deduct 1186 from 1549 and we're left with 363.
Include the next digit (3) from the dividend after 363, then repeat: 3633 / 593

Step 6:
The number 593 fits into 3633 6 times, leaving a remainder of 75.
The number 6 becomes the next digit in our result. 
Result so far: 1326.0
The remainder is 75 after subtracting 3558 from 3633.
Bring next digit (7) of the dividend behind the 75 and repeat the process: 757 / 593

Going ahead to step 7:
757 divided by 593 is 1 with a remainder of 164.
The next digit of our result is 1. 
Result so far: 13261.0
Deduct 593 from 757 and we're left with 164.
Include the next digit (8) from the dividend after 164, then repeat: 1648 / 593

Step 8:
1648 divided by 593 is 2 with a remainder of 462.
Write down 2 as next digit of the result. 
Result so far: 132612.0
Subtracting 1186 from 1648 leaves us with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Let's proceed to step 9:
If we divide 4620 by 593, we get 7 and a remainder of 469.
Use 7 as the next digit of our solution. 
Result so far: 132612.7
If we subtract 4151 from 4620, we get 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Moving on to step 10:
4690 divided by 593 is 7 with a remainder of 539.
Use 7 as the next digit of our solution. 
Result so far: 132612.77
Deduct 4151 from 4690 and we're left with 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

In conclusion, the division gives 132612.77 with a balance of 0.539.
