We're dividing 661213 by 78 
Let's see how many times 78 fits into 661213.

Going ahead to step 1:
When dividing 6 by 78, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
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 / 78

Advancing to step 2:
78 can be fit into 66 0 times, resulting in a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Bring next digit (1) of the dividend behind the 66 and repeat the process: 661 / 78

Going ahead to step 3:
661 divided by 78 is 8 with a remainder of 37.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 624 from 661 to get 37.
Include the next digit (2) from the dividend after 37, then repeat: 372 / 78

Moving on to step 4:
When dividing 372 by 78, we get 4 with a remainder of 60.
The next digit of our result is 4. 
Result so far: 84.0
Subtracting 312 from 372 leaves us with 60.
Include the next digit (1) from the dividend after 60, then repeat: 601 / 78

Step 5:
78 can be fit into 601 7 times, resulting in a remainder of 55.
Use 7 as the next digit of our solution. 
Result so far: 847.0
Deduct 546 from 601 and we're left with 55.
Include the next digit (3) from the dividend after 55, then repeat: 553 / 78

On to step 6:
78 can be fit into 553 7 times, resulting in a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 8477.0
Deduct 546 from 553 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
When dividing 70 by 78, we get 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 8477.0
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 8:
The number 78 fits into 700 8 times, leaving a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 8477.08
Deduct 624 from 700 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 9:
78 can be fit into 760 9 times, resulting in a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 8477.089
If we take 702 away from 760, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 10:
If we divide 580 by 78, we get 7 and a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 8477.0897
If we take 546 away from 580, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 11:
78 goes into 340 4 times with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 8477.08974
If we take 312 away from 340, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
280 divided by 78 is 3 with a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 8477.089743
If we take 234 away from 280, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 13:
78 can be fit into 460 5 times, resulting in a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 8477.0897435
Subtracting 390 from 460 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 14:
78 can be fit into 700 8 times, resulting in a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 8477.08974358
The remainder is 76 after subtracting 624 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The quotient of the division is 8477.08974358, and the remainder is 7.6e-08.
