Let's divide 78400014 by 315
We want to figure out the number of times 78400014 can be divided by 315.

Step 1:
315 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 315

On to step 2:
The number 315 fits into 78 0 times, leaving a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Grab the next digit (4) from the dividend, add it to 78, then carry on: 784 / 315

Let's proceed to step 3:
When dividing 784 by 315, we get 2 with a remainder of 154.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 630 from 784 and we're left with 154.
Bring next digit (0) of the dividend behind the 154 and repeat the process: 1540 / 315

Going ahead to step 4:
If we divide 1540 by 315, we get 4 and a remainder of 280.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Subtract 1260 from 1540 to get 280.
Fetch the next digit (0) from the dividend, attach it to 280 and continue: 2800 / 315

Moving on to step 5:
2800 divided by 315 is 8 with a remainder of 280.
Put 8 as the next digit of the answer. 
Result so far: 248.0
Deduct 2520 from 2800 and we're left with 280.
Fetch the next digit (0) from the dividend, attach it to 280 and continue: 2800 / 315

Going ahead to step 6:
If we divide 2800 by 315, we get 8 and a remainder of 280.
Put 8 as the next digit of the answer. 
Result so far: 2488.0
If we take 2520 away from 2800, we end up with 280.
Grab the next digit (1) from the dividend, add it to 280, then carry on: 2801 / 315

Moving on to step 7:
315 can be fit into 2801 8 times, resulting in a remainder of 281.
Use 8 as the next digit of our solution. 
Result so far: 24888.0
Deduct 2520 from 2801 and we're left with 281.
Include the next digit (4) from the dividend after 281, then repeat: 2814 / 315

Advancing to step 8:
If we divide 2814 by 315, we get 8 and a remainder of 294.
The next digit of our result is 8. 
Result so far: 248888.0
Deduct 2520 from 2814 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Let's proceed to step 9:
2940 divided by 315 is 9 with a remainder of 105.
Use 9 as the next digit of our solution. 
Result so far: 248888.9
The remainder is 105 after subtracting 2835 from 2940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 10:
1050 divided by 315 is 3 with a remainder of 105.
Record the quotient 3 as the next digit in the result. 
Result so far: 248888.93
Subtracting 945 from 1050 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 11:
The number 315 fits into 1050 3 times, leaving a remainder of 105.
Use 3 as the next digit of our solution. 
Result so far: 248888.933
The remainder is 105 after subtracting 945 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

After the division, we end up with 248888.933 and a remainder of 0.0105.
