On to step 1:
The number 678 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 678

Let's proceed to step 2:
42 divided by 678 is 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Grab the next digit (5) from the dividend, add it to 42, then carry on: 425 / 678

Going ahead to step 3:
The number 678 fits into 425 0 times, leaving a remainder of 425.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 425 after subtracting 0 from 425.
Fetch the next digit (9) from the dividend, attach it to 425 and continue: 4259 / 678

Moving on to step 4:
4259 divided by 678 is 6 with a remainder of 191.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 4068 from 4259, we get 191.
Grab the next digit (2) from the dividend, add it to 191, then carry on: 1912 / 678

Going ahead to step 5:
If we divide 1912 by 678, we get 2 and a remainder of 556.
Write down 2 as next digit of the result. 
Result so far: 62.0
The remainder is 556 after subtracting 1356 from 1912.
Append the next digit (5) from the dividend to 556 and continue with: 5565 / 678

On to step 6:
When dividing 5565 by 678, we get 8 with a remainder of 141.
The number 8 becomes the next digit in our result. 
Result so far: 628.0
The remainder is 141 after subtracting 5424 from 5565.
Grab the next digit (3) from the dividend, add it to 141, then carry on: 1413 / 678

Advancing to step 7:
678 goes into 1413 2 times with a remainder of 57.
The next digit of our result is 2. 
Result so far: 6282.0
If we subtract 1356 from 1413, we get 57.
Include the next digit (5) from the dividend after 57, then repeat: 575 / 678

Let's proceed to step 8:
575 divided by 678 is 0 with a remainder of 575.
Use 0 as the next digit of our solution. 
Result so far: 62820.0
Subtract 0 from 575 to get 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Moving on to step 9:
5750 divided by 678 is 8 with a remainder of 326.
Use 8 as the next digit of our solution. 
Result so far: 62820.8
Subtracting 5424 from 5750 leaves us with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Going ahead to step 10:
678 can be fit into 3260 4 times, resulting in a remainder of 548.
Use 4 as the next digit of our solution. 
Result so far: 62820.84
If we subtract 2712 from 3260, we get 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Moving on to step 11:
If we divide 5480 by 678, we get 8 and a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 62820.848
Subtract 5424 from 5480 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 12:
678 goes into 560 0 times with a remainder of 560.
Use 0 as the next digit of our solution. 
Result so far: 62820.848
Subtract 0 from 560 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 13:
When dividing 5600 by 678, we get 8 with a remainder of 176.
Write down 8 as next digit of the result. 
Result so far: 62820.84808
Deduct 5424 from 5600 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 14:
678 can be fit into 1760 2 times, resulting in a remainder of 404.
Record the quotient 2 as the next digit in the result. 
Result so far: 62820.848082
The remainder is 404 after subtracting 1356 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Let's proceed to step 15:
The number 678 fits into 4040 5 times, leaving a remainder of 650.
Use 5 as the next digit of our solution. 
Result so far: 62820.8480825
Subtract 3390 from 4040 to get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Let's proceed to step 16:
678 goes into 6500 9 times with a remainder of 398.
The next digit of our result is 9. 
Result so far: 62820.84808259
The remainder is 398 after subtracting 6102 from 6500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

In conclusion, the division gives 62820.84808259 with a balance of 3.98e-07.
