We divide 668780 by 84
Let's see how many times 84 fits into 668780.

Moving on to step 1:
84 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 84

Let's proceed to step 2:
The number 84 fits into 66 0 times, leaving a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 84

Let's proceed to step 3:
84 goes into 668 7 times with a remainder of 80.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 588 away from 668, we end up with 80.
Grab the next digit (7) from the dividend, add it to 80, then carry on: 807 / 84

Going ahead to step 4:
84 can be fit into 807 9 times, resulting in a remainder of 51.
The next digit of our result is 9. 
Result so far: 79.0
Subtract 756 from 807 to get 51.
Bring next digit (8) of the dividend behind the 51 and repeat the process: 518 / 84

Step 5:
If we divide 518 by 84, we get 6 and a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 796.0
Subtracting 504 from 518 leaves us with 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 84

Going ahead to step 6:
The number 84 fits into 140 1 times, leaving a remainder of 56.
Use 1 as the next digit of our solution. 
Result so far: 7961.0
Deduct 84 from 140 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 7:
84 goes into 560 6 times with a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 7961.6
Subtract 504 from 560 to 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.

Moving on to step 8:
If we divide 560 by 84, we get 6 and a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 7961.66
Deduct 504 from 560 and we're left with 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 result is 7961.66 with a remainder of 0.056.
