Advancing to step 2:
The number 645 fits into 68 0 times, leaving a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Fetch the next digit (5) from the dividend, attach it to 68 and continue: 685 / 645

Step 3:
If we divide 685 by 645, we get 1 and a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 645 from 685 leaves us with 40.
Fetch the next digit (7) from the dividend, attach it to 40 and continue: 407 / 645

Moving on to step 4:
645 can be fit into 407 0 times, resulting in a remainder of 407.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 407 to get 407.
Take the next digit (8) from the dividend and append it to 407, then repeat: 4078 / 645

Advancing to step 5:
The number 645 fits into 4078 6 times, leaving a remainder of 208.
Put 6 as the next digit of the answer. 
Result so far: 106.0
Subtract 3870 from 4078 to get 208.
Include the next digit (8) from the dividend after 208, then repeat: 2088 / 645

Going ahead to step 6:
The number 645 fits into 2088 3 times, leaving a remainder of 153.
The number 3 becomes the next digit in our result. 
Result so far: 1063.0
Subtract 1935 from 2088 to get 153.
Take the next digit (4) from the dividend and append it to 153, then repeat: 1534 / 645

Going ahead to step 7:
The number 645 fits into 1534 2 times, leaving a remainder of 244.
Write down 2 as next digit of the result. 
Result so far: 10632.0
The remainder is 244 after subtracting 1290 from 1534.
Include the next digit (2) from the dividend after 244, then repeat: 2442 / 645

Moving on to step 8:
645 goes into 2442 3 times with a remainder of 507.
Use 3 as the next digit of our solution. 
Result so far: 106323.0
Deduct 1935 from 2442 and we're left with 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Step 9:
645 can be fit into 5070 7 times, resulting in a remainder of 555.
The number 7 becomes the next digit in our result. 
Result so far: 106323.7
Subtract 4515 from 5070 to get 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Going ahead to step 10:
645 goes into 5550 8 times with a remainder of 390.
Write down 8 as next digit of the result. 
Result so far: 106323.78
If we take 5160 away from 5550, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 11:
When dividing 3900 by 645, we get 6 with a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 106323.786
Deduct 3870 from 3900 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
The number 645 fits into 300 0 times, leaving a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 106323.786
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 13:
645 can be fit into 3000 4 times, resulting in a remainder of 420.
Write down 4 as next digit of the result. 
Result so far: 106323.78604
If we take 2580 away from 3000, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 14:
4200 divided by 645 is 6 with a remainder of 330.
Record the quotient 6 as the next digit in the result. 
Result so far: 106323.786046
If we take 3870 away from 4200, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 15:
If we divide 3300 by 645, we get 5 and a remainder of 75.
The next digit of our result is 5. 
Result so far: 106323.7860465
Deduct 3225 from 3300 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 16:
645 goes into 750 1 times with a remainder of 105.
Use 1 as the next digit of our solution. 
Result so far: 106323.78604651
Deduct 645 from 750 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The quotient of the division is 106323.78604651, and the remainder is 1.05e-07.
