679379 ÷ 78 
We want to divide 679379 by 78.

Moving on to step 1:
The number 78 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 78

Moving on to step 2:
The number 78 fits into 67 0 times, leaving a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 67 after subtracting 0 from 67.
Fetch the next digit (9) from the dividend, attach it to 67 and continue: 679 / 78

Moving on to step 3:
The number 78 fits into 679 8 times, leaving a remainder of 55.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 624 away from 679, we end up with 55.
Grab the next digit (3) from the dividend, add it to 55, then carry on: 553 / 78

Let's proceed to step 4:
If we divide 553 by 78, we get 7 and a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
Subtract 546 from 553 to get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 78

Step 5:
77 divided by 78 is 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 870.0
Subtract 0 from 77 to get 77.
Append the next digit (9) from the dividend to 77 and continue with: 779 / 78

Moving on to step 6:
If we divide 779 by 78, we get 9 and a remainder of 77.
The number 9 becomes the next digit in our result. 
Result so far: 8709.0
Subtracting 702 from 779 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 7:
If we divide 770 by 78, we get 9 and a remainder of 68.
Write down 9 as next digit of the result. 
Result so far: 8709.9
Subtract 702 from 770 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 8:
78 goes into 680 8 times with a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 8709.98
If we subtract 624 from 680, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 9:
78 goes into 560 7 times with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 8709.987
The remainder is 14 after subtracting 546 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
78 can be fit into 140 1 times, resulting in a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 8709.9871
If we take 78 away from 140, we end up 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.

Let's proceed to step 11:
78 can be fit into 620 7 times, resulting in a remainder of 74.
The number 7 becomes the next digit in our result. 
Result so far: 8709.98717
Subtract 546 from 620 to get 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:
If we divide 740 by 78, we get 9 and a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 8709.987179
If we subtract 702 from 740, we 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.

Let's proceed to step 13:
When dividing 380 by 78, we get 4 with a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 8709.9871794
Subtract 312 from 380 to get 68.
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 14:
680 divided by 78 is 8 with a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 8709.98717948
If we subtract 624 from 680, we get 56.
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 8709.98717948, with a leftover of 5.6e-08.
