We look at the division of 436519 by 78 
Our goal is to divide 436519 by 78.

Step 1:
78 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 78

Step 2:
The number 78 fits into 43 0 times, leaving a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Append the next digit (6) from the dividend to 43 and continue with: 436 / 78

Let's proceed to step 3:
If we divide 436 by 78, we get 5 and a remainder of 46.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 46 after subtracting 390 from 436.
Take the next digit (5) from the dividend and append it to 46, then repeat: 465 / 78

On to step 4:
If we divide 465 by 78, we get 5 and a remainder of 75.
The next digit of our result is 5. 
Result so far: 55.0
If we take 390 away from 465, we end up with 75.
Bring next digit (1) of the dividend behind the 75 and repeat the process: 751 / 78

Step 5:
If we divide 751 by 78, we get 9 and a remainder of 49.
Write down 9 as next digit of the result. 
Result so far: 559.0
If we subtract 702 from 751, we get 49.
Include the next digit (9) from the dividend after 49, then repeat: 499 / 78

Step 6:
If we divide 499 by 78, we get 6 and a remainder of 31.
Record the quotient 6 as the next digit in the result. 
Result so far: 5596.0
Subtract 468 from 499 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 7:
When dividing 310 by 78, we get 3 with a remainder of 76.
The next digit of our result is 3. 
Result so far: 5596.3
Subtract 234 from 310 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 8:
78 goes into 760 9 times with a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 5596.39
The remainder is 58 after subtracting 702 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 9:
If we divide 580 by 78, we get 7 and a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 5596.397
Subtracting 546 from 580 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
If we divide 340 by 78, we get 4 and a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 5596.3974
Subtract 312 from 340 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 11:
78 can be fit into 280 3 times, resulting in a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 5596.39743
Subtract 234 from 280 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 12:
The number 78 fits into 460 5 times, leaving a remainder of 70.
The next digit of our result is 5. 
Result so far: 5596.397435
Subtracting 390 from 460 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 13:
If we divide 700 by 78, we get 8 and a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 5596.3974358
Subtract 624 from 700 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 14:
If we divide 760 by 78, we get 9 and a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 5596.39743589
Subtracting 702 from 760 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

After the division, we end up with 5596.39743589 and a remainder of 5.8e-08.
