685736 divided by 78 
Our goal is to divide 685736 by 78.

Moving on to step 1:
The number 78 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 78

On to step 2:
If we divide 68 by 78, we get 0 and a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Include the next digit (5) from the dividend after 68, then repeat: 685 / 78

Going ahead to step 3:
If we divide 685 by 78, we get 8 and a remainder of 61.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 624 from 685 to get 61.
Append the next digit (7) from the dividend to 61 and continue with: 617 / 78

Advancing to step 4:
When dividing 617 by 78, we get 7 with a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 87.0
Subtracting 546 from 617 leaves us with 71.
Append the next digit (3) from the dividend to 71 and continue with: 713 / 78

Step 5:
713 divided by 78 is 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 879.0
If we subtract 702 from 713, we get 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 78

Moving on to step 6:
78 can be fit into 116 1 times, resulting in a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 8791.0
If we take 78 away from 116, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 7:
380 divided by 78 is 4 with a remainder of 68.
The next digit of our result is 4. 
Result so far: 8791.4
The remainder is 68 after subtracting 312 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 8:
If we divide 680 by 78, we get 8 and a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 8791.48
The remainder is 56 after subtracting 624 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 9:
78 goes into 560 7 times with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 8791.487
If we subtract 546 from 560, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
The number 78 fits into 140 1 times, leaving a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 8791.4871
Deduct 78 from 140 and we're left 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.

On to step 11:
78 goes into 620 7 times with a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 8791.48717
Subtracting 546 from 620 leaves us 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.

Step 12:
78 goes into 740 9 times with a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 8791.487179
Subtract 702 from 740 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 13:
78 goes into 380 4 times with a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 8791.4871794
If we take 312 away from 380, we end up with 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:
If we divide 680 by 78, we get 8 and a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 8791.48717948
The remainder is 56 after subtracting 624 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final outcome is 8791.48717948, with a leftover of 5.6e-08.
