715405 ÷ 78 
We're looking to find how many times 78 goes into 715405.

Advancing to step 1:
When dividing 7 by 78, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 78

Advancing to step 2:
When dividing 71 by 78, we get 0 with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Include the next digit (5) from the dividend after 71, then repeat: 715 / 78

Let's proceed to step 3:
715 divided by 78 is 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 702 from 715 and we're left with 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 78

Moving on to step 4:
78 goes into 134 1 times with a remainder of 56.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
The remainder is 56 after subtracting 78 from 134.
Include the next digit (0) from the dividend after 56, then repeat: 560 / 78

Advancing to step 5:
560 divided by 78 is 7 with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 917.0
Deduct 546 from 560 and we're left with 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 78

Moving on to step 6:
If we divide 145 by 78, we get 1 and a remainder of 67.
Write down 1 as next digit of the result. 
Result so far: 9171.0
Subtracting 78 from 145 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 7:
78 goes into 670 8 times with a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 9171.8
Subtract 624 from 670 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 8:
460 divided by 78 is 5 with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 9171.85
Subtract 390 from 460 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
78 can be fit into 700 8 times, resulting in a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 9171.858
Deduct 624 from 700 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 10:
78 can be fit into 760 9 times, resulting in a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 9171.8589
Deduct 702 from 760 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 11:
580 divided by 78 is 7 with a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 9171.85897
If we subtract 546 from 580, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 12:
78 can be fit into 340 4 times, resulting in a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 9171.858974
If we take 312 away from 340, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 13:
280 divided by 78 is 3 with a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 9171.8589743
If we take 234 away from 280, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 14:
78 goes into 460 5 times with a remainder of 70.
The next digit of our result is 5. 
Result so far: 9171.85897435
The remainder is 70 after subtracting 390 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 9171.85897435, with a leftover of 7e-08.
