17394696 ÷ 78 
We're looking to find how many times 78 goes into 17394696.

Moving on to step 1:
78 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 78

On to step 2:
When dividing 17 by 78, we get 0 with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 78

Let's proceed to step 3:
If we divide 173 by 78, we get 2 and a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 156 from 173 and we're left with 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 78

Moving on to step 4:
179 divided by 78 is 2 with a remainder of 23.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Deduct 156 from 179 and we're left with 23.
Fetch the next digit (4) from the dividend, attach it to 23 and continue: 234 / 78

On to step 5:
When dividing 234 by 78, we get 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 223.0
Deduct 234 from 234 and we're left with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 78

On to step 6:
78 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 2230.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 78

Moving on to step 7:
If we divide 69 by 78, we get 0 and a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 22300.0
If we subtract 0 from 69, we get 69.
Include the next digit (6) from the dividend after 69, then repeat: 696 / 78

On to step 8:
78 goes into 696 8 times with a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 223008.0
Subtract 624 from 696 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 9:
If we divide 720 by 78, we get 9 and a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 223008.9
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 10:
When dividing 180 by 78, we get 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 223008.92
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
78 goes into 240 3 times with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 223008.923
Deduct 234 from 240 and we're left with 6.
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 12:
If we divide 60 by 78, we get 0 and a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 223008.923
If we subtract 0 from 60, we 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.

Step 13:
600 divided by 78 is 7 with a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 223008.92307
Subtracting 546 from 600 leaves us with 54.
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 14:
When dividing 540 by 78, we get 6 with a remainder of 72.
The next digit of our result is 6. 
Result so far: 223008.923076
Deduct 468 from 540 and we're left with 72.
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 15:
720 divided by 78 is 9 with a remainder of 18.
The next digit of our result is 9. 
Result so far: 223008.9230769
The remainder is 18 after subtracting 702 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 16:
When dividing 180 by 78, we get 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 223008.92307692
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.

The final result is 223008.92307692 with a remainder of 2.4e-08.
