We're dividing 749849 by 78 
Let's see how many times 78 fits into 749849.

Step 1:
When dividing 7 by 78, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 78

On to step 2:
74 divided by 78 is 0 with a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Append the next digit (9) from the dividend to 74 and continue with: 749 / 78

Step 3:
78 goes into 749 9 times with a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 47 after subtracting 702 from 749.
Include the next digit (8) from the dividend after 47, then repeat: 478 / 78

Moving on to step 4:
The number 78 fits into 478 6 times, leaving a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 96.0
The remainder is 10 after subtracting 468 from 478.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 78

Going ahead to step 5:
When dividing 104 by 78, we get 1 with a remainder of 26.
The next digit of our result is 1. 
Result so far: 961.0
Subtracting 78 from 104 leaves us with 26.
Grab the next digit (9) from the dividend, add it to 26, then carry on: 269 / 78

Advancing to step 6:
78 can be fit into 269 3 times, resulting in a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 9613.0
Subtract 234 from 269 to 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.

On to step 7:
When dividing 350 by 78, we get 4 with a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 9613.4
Deduct 312 from 350 and we're left with 38.
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:
If we divide 380 by 78, we get 4 and a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 9613.44
If we subtract 312 from 380, we get 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 final outcome is 9613.44, with a leftover of 0.068.
