Advancing to step 1:
78 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 78

Advancing to step 2:
38 divided by 78 is 0 with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Fetch the next digit (1) from the dividend, attach it to 38 and continue: 381 / 78

Moving on to step 3:
The number 78 fits into 381 4 times, leaving a remainder of 69.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 312 from 381 and we're left with 69.
Append the next digit (3) from the dividend to 69 and continue with: 693 / 78

Going ahead to step 4:
When dividing 693 by 78, we get 8 with a remainder of 69.
Write down 8 as next digit of the result. 
Result so far: 48.0
The remainder is 69 after subtracting 624 from 693.
Take the next digit (9) from the dividend and append it to 69, then repeat: 699 / 78

Moving on to step 5:
If we divide 699 by 78, we get 8 and a remainder of 75.
Put 8 as the next digit of the answer. 
Result so far: 488.0
If we subtract 624 from 699, we get 75.
Grab the next digit (4) from the dividend, add it to 75, then carry on: 754 / 78

Moving on to step 6:
78 can be fit into 754 9 times, resulting in a remainder of 52.
Put 9 as the next digit of the answer. 
Result so far: 4889.0
Subtract 702 from 754 to 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.

Step 7:
When dividing 520 by 78, we get 6 with a remainder of 52.
The next digit of our result is 6. 
Result so far: 4889.6
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.

Advancing to step 8:
78 can be fit into 520 6 times, resulting in a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 4889.66
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.
