670693 divided by 78 
Let's see how many times 78 fits into 670693.

Moving on to step 1:
If we divide 6 by 78, we get 0 and 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.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 78

Step 2:
78 goes into 67 0 times with a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Include the next digit (0) from the dividend after 67, then repeat: 670 / 78

Advancing to step 3:
78 can be fit into 670 8 times, resulting in a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 624 from 670, we get 46.
Grab the next digit (6) from the dividend, add it to 46, then carry on: 466 / 78

Moving on to step 4:
78 goes into 466 5 times with a remainder of 76.
The next digit of our result is 5. 
Result so far: 85.0
Deduct 390 from 466 and we're left with 76.
Append the next digit (9) from the dividend to 76 and continue with: 769 / 78

Going ahead to step 5:
When dividing 769 by 78, we get 9 with a remainder of 67.
The next digit of our result is 9. 
Result so far: 859.0
Subtracting 702 from 769 leaves us with 67.
Fetch the next digit (3) from the dividend, attach it to 67 and continue: 673 / 78

Let's proceed to step 6:
The number 78 fits into 673 8 times, leaving a remainder of 49.
The number 8 becomes the next digit in our result. 
Result so far: 8598.0
The remainder is 49 after subtracting 624 from 673.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 7:
If we divide 490 by 78, we get 6 and a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 8598.6
If we subtract 468 from 490, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
78 can be fit into 220 2 times, resulting in a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 8598.62
The remainder is 64 after subtracting 156 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 9:
640 divided by 78 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 8598.628
If we subtract 624 from 640, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
160 divided by 78 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 8598.6282
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
When dividing 40 by 78, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 8598.6282
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
400 divided by 78 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 8598.628205
The remainder is 10 after subtracting 390 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
100 divided by 78 is 1 with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 8598.6282051
If we subtract 78 from 100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 14:
220 divided by 78 is 2 with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 8598.62820512
Subtracting 156 from 220 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 8598.62820512 with a balance of 6.4e-08.
