We look at the division of 619918 by 78 
Let's see how many times 78 fits into 619918.

Advancing to step 1:
When dividing 6 by 78, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 78

Let's proceed to step 2:
78 can be fit into 61 0 times, resulting in a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 61 leaves us with 61.
Take the next digit (9) from the dividend and append it to 61, then repeat: 619 / 78

On to step 3:
78 goes into 619 7 times with a remainder of 73.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 546 from 619 leaves us with 73.
Take the next digit (9) from the dividend and append it to 73, then repeat: 739 / 78

Going ahead to step 4:
78 can be fit into 739 9 times, resulting in a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
If we subtract 702 from 739, we get 37.
Take the next digit (1) from the dividend and append it to 37, then repeat: 371 / 78

Advancing to step 5:
The number 78 fits into 371 4 times, leaving a remainder of 59.
Use 4 as the next digit of our solution. 
Result so far: 794.0
The remainder is 59 after subtracting 312 from 371.
Take the next digit (8) from the dividend and append it to 59, then repeat: 598 / 78

On to step 6:
When dividing 598 by 78, we get 7 with a remainder of 52.
The next digit of our result is 7. 
Result so far: 7947.0
Deduct 546 from 598 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 7:
When dividing 520 by 78, we get 6 with a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 7947.6
If we subtract 468 from 520, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 8:
The number 78 fits into 520 6 times, leaving a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 7947.66
Subtracting 468 from 520 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The quotient of the division is 7947.66, and the remainder is 0.052.
