19021019 ÷ 78 
We want to figure out the number of times 19021019 can be divided by 78.

Step 1:
1 divided by 78 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 78

Moving on to step 2:
78 goes into 19 0 times with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 78

Let's proceed to step 3:
When dividing 190 by 78, we get 2 with a remainder of 34.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 156 from 190 to get 34.
Fetch the next digit (2) from the dividend, attach it to 34 and continue: 342 / 78

Advancing to step 4:
The number 78 fits into 342 4 times, leaving a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Subtracting 312 from 342 leaves us with 30.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 78

On to step 5:
301 divided by 78 is 3 with a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 243.0
If we subtract 234 from 301, we get 67.
Append the next digit (0) from the dividend to 67 and continue with: 670 / 78

Step 6:
When dividing 670 by 78, we get 8 with a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 2438.0
If we take 624 away from 670, we end up with 46.
Include the next digit (1) from the dividend after 46, then repeat: 461 / 78

On to step 7:
When dividing 461 by 78, we get 5 with a remainder of 71.
The number 5 becomes the next digit in our result. 
Result so far: 24385.0
If we take 390 away from 461, we end up with 71.
Take the next digit (9) from the dividend and append it to 71, then repeat: 719 / 78

Advancing to step 8:
The number 78 fits into 719 9 times, leaving a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 243859.0
If we take 702 away from 719, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 9:
170 divided by 78 is 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 243859.2
The remainder is 14 after subtracting 156 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
The number 78 fits into 140 1 times, leaving a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 243859.21
If we take 78 away from 140, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 11:
78 goes into 620 7 times with a remainder of 74.
The number 7 becomes the next digit in our result. 
Result so far: 243859.217
Deduct 546 from 620 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 12:
78 can be fit into 740 9 times, resulting in a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 243859.2179
The remainder is 38 after subtracting 702 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 13:
If we divide 380 by 78, we get 4 and a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 243859.21794
If we subtract 312 from 380, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 14:
680 divided by 78 is 8 with a remainder of 56.
The next digit of our result is 8. 
Result so far: 243859.217948
Subtracting 624 from 680 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 15:
78 goes into 560 7 times with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 243859.2179487
Deduct 546 from 560 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 16:
When dividing 140 by 78, we get 1 with a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 243859.21794871
The remainder is 62 after subtracting 78 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Our division results in 243859.21794871 with a remaining 6.2e-08.
