We're dividing 689880 by 78 
We're looking to find how many times 78 goes into 689880.

Advancing to step 1:
If we divide 6 by 78, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 78

Going ahead to step 2:
The number 78 fits into 68 0 times, leaving a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Include the next digit (9) from the dividend after 68, then repeat: 689 / 78

Moving on to step 3:
When dividing 689 by 78, we get 8 with a remainder of 65.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 624 from 689 to get 65.
Grab the next digit (8) from the dividend, add it to 65, then carry on: 658 / 78

Moving on to step 4:
When dividing 658 by 78, we get 8 with a remainder of 34.
The next digit of our result is 8. 
Result so far: 88.0
If we take 624 away from 658, we end up with 34.
Bring next digit (8) of the dividend behind the 34 and repeat the process: 348 / 78

Step 5:
78 goes into 348 4 times with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 884.0
Deduct 312 from 348 and we're left with 36.
Append the next digit (0) from the dividend to 36 and continue with: 360 / 78

On to step 6:
The number 78 fits into 360 4 times, leaving a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 8844.0
If we take 312 away from 360, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 7:
When dividing 480 by 78, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 8844.6
If we subtract 468 from 480, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
The number 78 fits into 120 1 times, leaving a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 8844.61
Subtract 78 from 120 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 9:
The number 78 fits into 420 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 8844.615
If we take 390 away from 420, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
If we divide 300 by 78, we get 3 and a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 8844.6153
Subtract 234 from 300 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 11:
78 goes into 660 8 times with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 8844.61538
Deduct 624 from 660 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 12:
The number 78 fits into 360 4 times, leaving a remainder of 48.
The next digit of our result is 4. 
Result so far: 8844.615384
Subtracting 312 from 360 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 13:
The number 78 fits into 480 6 times, leaving a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 8844.6153846
If we subtract 468 from 480, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 14:
78 can be fit into 120 1 times, resulting in a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 8844.61538461
If we take 78 away from 120, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The quotient of the division is 8844.61538461, and the remainder is 4.2e-08.
