We look at the division of 78319819 by 715 
We're looking to find how many times 715 goes into 78319819.

Step 1:
715 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 715

Advancing to step 2:
78 divided by 715 is 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Include the next digit (3) from the dividend after 78, then repeat: 783 / 715

Let's proceed to step 3:
715 can be fit into 783 1 times, resulting in a remainder of 68.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 715 from 783 leaves us with 68.
Append the next digit (1) from the dividend to 68 and continue with: 681 / 715

Going ahead to step 4:
If we divide 681 by 715, we get 0 and a remainder of 681.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 681, we get 681.
Fetch the next digit (9) from the dividend, attach it to 681 and continue: 6819 / 715

On to step 5:
715 goes into 6819 9 times with a remainder of 384.
Put 9 as the next digit of the answer. 
Result so far: 109.0
Subtract 6435 from 6819 to get 384.
Take the next digit (8) from the dividend and append it to 384, then repeat: 3848 / 715

Let's proceed to step 6:
When dividing 3848 by 715, we get 5 with a remainder of 273.
Record the quotient 5 as the next digit in the result. 
Result so far: 1095.0
Deduct 3575 from 3848 and we're left with 273.
Append the next digit (1) from the dividend to 273 and continue with: 2731 / 715

Advancing to step 7:
2731 divided by 715 is 3 with a remainder of 586.
Write down 3 as next digit of the result. 
Result so far: 10953.0
The remainder is 586 after subtracting 2145 from 2731.
Fetch the next digit (9) from the dividend, attach it to 586 and continue: 5869 / 715

Step 8:
The number 715 fits into 5869 8 times, leaving a remainder of 149.
The number 8 becomes the next digit in our result. 
Result so far: 109538.0
Subtract 5720 from 5869 to get 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

On to step 9:
1490 divided by 715 is 2 with a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 109538.2
Subtracting 1430 from 1490 leaves us 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.

Step 10:
715 can be fit into 600 0 times, resulting in a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 109538.2
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 11:
715 goes into 6000 8 times with a remainder of 280.
The next digit of our result is 8. 
Result so far: 109538.208
If we subtract 5720 from 6000, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 12:
715 can be fit into 2800 3 times, resulting in a remainder of 655.
The number 3 becomes the next digit in our result. 
Result so far: 109538.2083
If we take 2145 away from 2800, we end up with 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

On to step 13:
If we divide 6550 by 715, we get 9 and a remainder of 115.
Use 9 as the next digit of our solution. 
Result so far: 109538.20839
Subtract 6435 from 6550 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 14:
715 goes into 1150 1 times with a remainder of 435.
Write down 1 as next digit of the result. 
Result so far: 109538.208391
Subtract 715 from 1150 to get 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Let's proceed to step 15:
When dividing 4350 by 715, we get 6 with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 109538.2083916
If we take 4290 away from 4350, we end up 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:
715 goes into 600 0 times with a remainder of 600.
Use 0 as the next digit of our solution. 
Result so far: 109538.2083916
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

In conclusion, the division gives 109538.2083916 with a balance of 6e-07.
