Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 648

Advancing to step 2:
The number 648 fits into 69 0 times, leaving a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 69 after subtracting 0 from 69.
Append the next digit (7) from the dividend to 69 and continue with: 697 / 648

Let's proceed to step 3:
648 goes into 697 1 times with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 648 from 697, we get 49.
Grab the next digit (2) from the dividend, add it to 49, then carry on: 492 / 648

Going ahead to step 4:
492 divided by 648 is 0 with a remainder of 492.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 492, we get 492.
Grab the next digit (4) from the dividend, add it to 492, then carry on: 4924 / 648

Advancing to step 5:
When dividing 4924 by 648, we get 7 with a remainder of 388.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
If we subtract 4536 from 4924, we get 388.
Append the next digit (1) from the dividend to 388 and continue with: 3881 / 648

Moving on to step 6:
648 can be fit into 3881 5 times, resulting in a remainder of 641.
The number 5 becomes the next digit in our result. 
Result so far: 1075.0
If we subtract 3240 from 3881, we get 641.
Grab the next digit (9) from the dividend, add it to 641, then carry on: 6419 / 648

Advancing to step 7:
648 can be fit into 6419 9 times, resulting in a remainder of 587.
The number 9 becomes the next digit in our result. 
Result so far: 10759.0
Deduct 5832 from 6419 and we're left with 587.
Grab the next digit (2) from the dividend, add it to 587, then carry on: 5872 / 648

Let's proceed to step 8:
5872 divided by 648 is 9 with a remainder of 40.
Use 9 as the next digit of our solution. 
Result so far: 107599.0
Subtracting 5832 from 5872 leaves us 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.

Moving on to step 9:
400 divided by 648 is 0 with a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 107599.0
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 10:
The number 648 fits into 4000 6 times, leaving a remainder of 112.
Write down 6 as next digit of the result. 
Result so far: 107599.06
Deduct 3888 from 4000 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 11:
648 goes into 1120 1 times with a remainder of 472.
Write down 1 as next digit of the result. 
Result so far: 107599.061
If we subtract 648 from 1120, we get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

On to step 12:
When dividing 4720 by 648, we get 7 with a remainder of 184.
The next digit of our result is 7. 
Result so far: 107599.0617
Subtract 4536 from 4720 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 13:
The number 648 fits into 1840 2 times, leaving a remainder of 544.
Record the quotient 2 as the next digit in the result. 
Result so far: 107599.06172
The remainder is 544 after subtracting 1296 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Step 14:
The number 648 fits into 5440 8 times, leaving a remainder of 256.
Write down 8 as next digit of the result. 
Result so far: 107599.061728
If we take 5184 away from 5440, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 15:
When dividing 2560 by 648, we get 3 with a remainder of 616.
Write down 3 as next digit of the result. 
Result so far: 107599.0617283
Subtracting 1944 from 2560 leaves us with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Step 16:
648 goes into 6160 9 times with a remainder of 328.
Use 9 as the next digit of our solution. 
Result so far: 107599.06172839
If we take 5832 away from 6160, we end up with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

The final outcome is 107599.06172839, with a leftover of 3.28e-07.
