We're dividing 651690 by 78 
We're looking to find how many times 78 goes into 651690.

Let's proceed to step 1:
6 divided by 78 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 78

Step 2:
When dividing 65 by 78, we get 0 with a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Append the next digit (1) from the dividend to 65 and continue with: 651 / 78

Going ahead to step 3:
When dividing 651 by 78, we get 8 with a remainder of 27.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 624 from 651 to get 27.
Grab the next digit (6) from the dividend, add it to 27, then carry on: 276 / 78

Step 4:
78 goes into 276 3 times with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 83.0
Deduct 234 from 276 and we're left with 42.
Bring next digit (9) of the dividend behind the 42 and repeat the process: 429 / 78

Advancing to step 5:
78 goes into 429 5 times with a remainder of 39.
The number 5 becomes the next digit in our result. 
Result so far: 835.0
The remainder is 39 after subtracting 390 from 429.
Include the next digit (0) from the dividend after 39, then repeat: 390 / 78

Going ahead to step 6:
The number 78 fits into 390 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 8355.0
Subtracting 390 from 390 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
The number 78 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8355.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
78 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8355.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 8355.0 with a remainder of 0.0.
