We're dividing 19616304 by 78 
We want to figure out the number of times 19616304 can be divided by 78.

Advancing to step 1:
The number 78 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 78

Let's proceed to step 2:
If we divide 19 by 78, we get 0 and a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Include the next digit (6) from the dividend after 19, then repeat: 196 / 78

Advancing to step 3:
196 divided by 78 is 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 40 after subtracting 156 from 196.
Fetch the next digit (1) from the dividend, attach it to 40 and continue: 401 / 78

Step 4:
78 can be fit into 401 5 times, resulting in a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Deduct 390 from 401 and we're left with 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 78

Advancing to step 5:
78 goes into 116 1 times with a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 251.0
Subtracting 78 from 116 leaves us with 38.
Fetch the next digit (3) from the dividend, attach it to 38 and continue: 383 / 78

Going ahead to step 6:
383 divided by 78 is 4 with a remainder of 71.
Record the quotient 4 as the next digit in the result. 
Result so far: 2514.0
Deduct 312 from 383 and we're left with 71.
Take the next digit (0) from the dividend and append it to 71, then repeat: 710 / 78

On to step 7:
710 divided by 78 is 9 with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 25149.0
Subtract 702 from 710 to get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 78

Step 8:
When dividing 84 by 78, we get 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 251491.0
The remainder is 6 after subtracting 78 from 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
The number 78 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 251491.0
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 10:
78 goes into 600 7 times with a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 251491.07
The remainder is 54 after subtracting 546 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 11:
If we divide 540 by 78, we get 6 and a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 251491.076
The remainder is 72 after subtracting 468 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 12:
If we divide 720 by 78, we get 9 and a remainder of 18.
The next digit of our result is 9. 
Result so far: 251491.0769
If we subtract 702 from 720, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 13:
If we divide 180 by 78, we get 2 and a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 251491.07692
Subtracting 156 from 180 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 14:
The number 78 fits into 240 3 times, leaving a remainder of 6.
The next digit of our result is 3. 
Result so far: 251491.076923
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 15:
If we divide 60 by 78, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 251491.076923
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 16:
78 can be fit into 600 7 times, resulting in a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 251491.07692307
Subtract 546 from 600 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 251491.07692307 and a remainder of 5.4e-08.
