We look at the division of 789941 by 78 
We're looking to find how many times 78 goes into 789941.

Going ahead to step 1:
78 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 78

Going ahead to step 2:
78 divided by 78 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 78 from 78 leaves us with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 78

Moving on to step 3:
If we divide 9 by 78, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 78

Moving on to step 4:
99 divided by 78 is 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 101.0
The remainder is 21 after subtracting 78 from 99.
Bring next digit (4) of the dividend behind the 21 and repeat the process: 214 / 78

Moving on to step 5:
If we divide 214 by 78, we get 2 and a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 1012.0
The remainder is 58 after subtracting 156 from 214.
Include the next digit (1) from the dividend after 58, then repeat: 581 / 78

Advancing to step 6:
The number 78 fits into 581 7 times, leaving a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 10127.0
If we subtract 546 from 581, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
350 divided by 78 is 4 with a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 10127.4
The remainder is 38 after subtracting 312 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 8:
The number 78 fits into 380 4 times, leaving a remainder of 68.
The next digit of our result is 4. 
Result so far: 10127.44
If we take 312 away from 380, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The quotient of the division is 10127.44, and the remainder is 0.068.
