614649 ÷ 78 
We want to divide 614649 by 78.

Going ahead 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
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 78

Let's proceed to step 2:
78 can be fit into 61 0 times, resulting in a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Take the next digit (4) from the dividend and append it to 61, then repeat: 614 / 78

Step 3:
614 divided by 78 is 7 with a remainder of 68.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 68 after subtracting 546 from 614.
Append the next digit (6) from the dividend to 68 and continue with: 686 / 78

On to step 4:
The number 78 fits into 686 8 times, leaving a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Deduct 624 from 686 and we're left with 62.
Append the next digit (4) from the dividend to 62 and continue with: 624 / 78

Advancing to step 5:
When dividing 624 by 78, we get 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 788.0
If we take 624 away from 624, we end up with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 78

Advancing to step 6:
The number 78 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 7880.0
If we take 0 away from 9, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
The number 78 fits into 90 1 times, leaving a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 7880.1
Subtract 78 from 90 to 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.

Step 8:
If we divide 120 by 78, we get 1 and a remainder of 42.
The next digit of our result is 1. 
Result so far: 7880.11
Subtracting 78 from 120 leaves us 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 final result is 7880.11 with a remainder of 0.042.
