678685 divided by 54 
Our goal is to divide 678685 by 54.

Moving on to step 1:
When dividing 6 by 54, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 54

Going ahead to step 2:
67 divided by 54 is 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 13 after subtracting 54 from 67.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 54

Moving on to step 3:
138 divided by 54 is 2 with a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 108 away from 138, we end up with 30.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 54

On to step 4:
306 divided by 54 is 5 with a remainder of 36.
Use 5 as the next digit of our solution. 
Result so far: 125.0
If we subtract 270 from 306, we get 36.
Include the next digit (8) from the dividend after 36, then repeat: 368 / 54

On to step 5:
368 divided by 54 is 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 1256.0
Subtracting 324 from 368 leaves us with 44.
Append the next digit (5) from the dividend to 44 and continue with: 445 / 54

Step 6:
445 divided by 54 is 8 with a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 12568.0
Subtract 432 from 445 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
54 goes into 130 2 times with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 12568.2
The remainder is 22 after subtracting 108 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
54 goes into 220 4 times with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 12568.24
The remainder is 4 after subtracting 216 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
40 divided by 54 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 12568.24
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
When dividing 400 by 54, we get 7 with a remainder of 22.
The next digit of our result is 7. 
Result so far: 12568.2407
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 11:
When dividing 220 by 54, we get 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 12568.24074
The remainder is 4 after subtracting 216 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
When dividing 40 by 54, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 12568.24074
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
54 goes into 400 7 times with a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 12568.2407407
Subtracting 378 from 400 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 14:
If we divide 220 by 54, we get 4 and a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 12568.24074074
Subtracting 216 from 220 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 12568.24074074, with a leftover of 4e-09.
