773942 divided by 78 
Let's see how many times 78 fits into 773942.

Moving on to step 1:
78 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 78

Going ahead to step 2:
The number 78 fits into 77 0 times, leaving a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Fetch the next digit (3) from the dividend, attach it to 77 and continue: 773 / 78

Let's proceed to step 3:
773 divided by 78 is 9 with a remainder of 71.
The next digit of our result is 9. 
Result so far: 9.0
If we take 702 away from 773, we end up with 71.
Take the next digit (9) from the dividend and append it to 71, then repeat: 719 / 78

Advancing to step 4:
If we divide 719 by 78, we get 9 and a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 99.0
If we take 702 away from 719, we end up with 17.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 78

Going ahead to step 5:
If we divide 174 by 78, we get 2 and a remainder of 18.
The next digit of our result is 2. 
Result so far: 992.0
Subtract 156 from 174 to get 18.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 78

Step 6:
78 can be fit into 182 2 times, resulting in a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 9922.0
Subtracting 156 from 182 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 7:
78 can be fit into 260 3 times, resulting in a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 9922.3
Subtracting 234 from 260 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 8:
78 can be fit into 260 3 times, resulting in a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 9922.33
The remainder is 26 after subtracting 234 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 9922.33 with a remainder of 0.026.
