We're dividing 42784903 by 78 
We want to figure out the number of times 42784903 can be divided by 78.

Step 1:
78 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 78

Moving on to step 2:
When dividing 42 by 78, we get 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Fetch the next digit (7) from the dividend, attach it to 42 and continue: 427 / 78

On to step 3:
427 divided by 78 is 5 with a remainder of 37.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 37 after subtracting 390 from 427.
Take the next digit (8) from the dividend and append it to 37, then repeat: 378 / 78

Let's proceed to step 4:
The number 78 fits into 378 4 times, leaving a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
The remainder is 66 after subtracting 312 from 378.
Include the next digit (4) from the dividend after 66, then repeat: 664 / 78

Step 5:
The number 78 fits into 664 8 times, leaving a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 548.0
If we subtract 624 from 664, we get 40.
Grab the next digit (9) from the dividend, add it to 40, then carry on: 409 / 78

Let's proceed to step 6:
If we divide 409 by 78, we get 5 and a remainder of 19.
The number 5 becomes the next digit in our result. 
Result so far: 5485.0
Subtracting 390 from 409 leaves us with 19.
Grab the next digit (0) from the dividend, add it to 19, then carry on: 190 / 78

On to step 7:
78 goes into 190 2 times with a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 54852.0
Deduct 156 from 190 and we're left with 34.
Take the next digit (3) from the dividend and append it to 34, then repeat: 343 / 78

Going ahead to step 8:
78 goes into 343 4 times with a remainder of 31.
Use 4 as the next digit of our solution. 
Result so far: 548524.0
If we take 312 away from 343, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 9:
78 can be fit into 310 3 times, resulting in a remainder of 76.
The next digit of our result is 3. 
Result so far: 548524.3
The remainder is 76 after subtracting 234 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 10:
When dividing 760 by 78, we get 9 with a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 548524.39
Subtract 702 from 760 to get 58.
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 11:
The number 78 fits into 580 7 times, leaving a remainder of 34.
The next digit of our result is 7. 
Result so far: 548524.397
If we subtract 546 from 580, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 12:
The number 78 fits into 340 4 times, leaving a remainder of 28.
The next digit of our result is 4. 
Result so far: 548524.3974
The remainder is 28 after subtracting 312 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 13:
If we divide 280 by 78, we get 3 and a remainder of 46.
The next digit of our result is 3. 
Result so far: 548524.39743
Deduct 234 from 280 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 14:
78 goes into 460 5 times with a remainder of 70.
The next digit of our result is 5. 
Result so far: 548524.397435
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.

Let's proceed to step 15:
When dividing 700 by 78, we get 8 with a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 548524.3974358
The remainder is 76 after subtracting 624 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 16:
760 divided by 78 is 9 with a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 548524.39743589
Deduct 702 from 760 and we're left 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.

The final result is 548524.39743589 with a remainder of 5.8e-08.
