Deduct 0 from 7 and we're left with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 648

Let's proceed to step 2:
648 goes into 77 0 times with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Take the next digit (9) from the dividend and append it to 77, then repeat: 779 / 648

On to step 3:
648 goes into 779 1 times with a remainder of 131.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 648 from 779 and we're left with 131.
Append the next digit (2) from the dividend to 131 and continue with: 1312 / 648

Advancing to step 4:
When dividing 1312 by 648, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 1296 from 1312 leaves us with 16.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 648

Going ahead to step 5:
When dividing 167 by 648, we get 0 with a remainder of 167.
The next digit of our result is 0. 
Result so far: 120.0
If we subtract 0 from 167, we get 167.
Fetch the next digit (6) from the dividend, attach it to 167 and continue: 1676 / 648

Let's proceed to step 6:
648 goes into 1676 2 times with a remainder of 380.
Use 2 as the next digit of our solution. 
Result so far: 1202.0
Subtracting 1296 from 1676 leaves us with 380.
Append the next digit (7) from the dividend to 380 and continue with: 3807 / 648

Going ahead to step 7:
When dividing 3807 by 648, we get 5 with a remainder of 567.
Put 5 as the next digit of the answer. 
Result so far: 12025.0
The remainder is 567 after subtracting 3240 from 3807.
Take the next digit (3) from the dividend and append it to 567, then repeat: 5673 / 648

Step 8:
If we divide 5673 by 648, we get 8 and a remainder of 489.
Write down 8 as next digit of the result. 
Result so far: 120258.0
The remainder is 489 after subtracting 5184 from 5673.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Advancing to step 9:
648 goes into 4890 7 times with a remainder of 354.
The next digit of our result is 7. 
Result so far: 120258.7
If we subtract 4536 from 4890, we get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Going ahead to step 10:
If we divide 3540 by 648, we get 5 and a remainder of 300.
Use 5 as the next digit of our solution. 
Result so far: 120258.75
Deduct 3240 from 3540 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 11:
648 can be fit into 3000 4 times, resulting in a remainder of 408.
Put 4 as the next digit of the answer. 
Result so far: 120258.754
The remainder is 408 after subtracting 2592 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

On to step 12:
648 can be fit into 4080 6 times, resulting in a remainder of 192.
Write down 6 as next digit of the result. 
Result so far: 120258.7546
The remainder is 192 after subtracting 3888 from 4080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 13:
1920 divided by 648 is 2 with a remainder of 624.
The next digit of our result is 2. 
Result so far: 120258.75462
If we take 1296 away from 1920, we end up with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

On to step 14:
648 goes into 6240 9 times with a remainder of 408.
Write down 9 as next digit of the result. 
Result so far: 120258.754629
Subtract 5832 from 6240 to get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Moving on to step 15:
If we divide 4080 by 648, we get 6 and a remainder of 192.
The number 6 becomes the next digit in our result. 
Result so far: 120258.7546296
Deduct 3888 from 4080 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 16:
648 goes into 1920 2 times with a remainder of 624.
The next digit of our result is 2. 
Result so far: 120258.75462962
The remainder is 624 after subtracting 1296 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

In conclusion, the division gives 120258.75462962 with a balance of 6.24e-07.
