We're dividing 9600065 by 645 
Let's see how many times 645 fits into 9600065.

Step 1:
When dividing 9 by 645, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 645

Let's proceed to step 2:
When dividing 96 by 645, we get 0 with a remainder of 96.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 96 after subtracting 0 from 96.
Include the next digit (0) from the dividend after 96, then repeat: 960 / 645

Let's proceed to step 3:
960 divided by 645 is 1 with a remainder of 315.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 645 from 960 and we're left with 315.
Grab the next digit (0) from the dividend, add it to 315, then carry on: 3150 / 645

Going ahead to step 4:
The number 645 fits into 3150 4 times, leaving a remainder of 570.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we subtract 2580 from 3150, we get 570.
Bring next digit (0) of the dividend behind the 570 and repeat the process: 5700 / 645

On to step 5:
645 can be fit into 5700 8 times, resulting in a remainder of 540.
The number 8 becomes the next digit in our result. 
Result so far: 148.0
The remainder is 540 after subtracting 5160 from 5700.
Take the next digit (6) from the dividend and append it to 540, then repeat: 5406 / 645

Going ahead to step 6:
The number 645 fits into 5406 8 times, leaving a remainder of 246.
The number 8 becomes the next digit in our result. 
Result so far: 1488.0
Subtracting 5160 from 5406 leaves us with 246.
Fetch the next digit (5) from the dividend, attach it to 246 and continue: 2465 / 645

Going ahead to step 7:
645 goes into 2465 3 times with a remainder of 530.
Put 3 as the next digit of the answer. 
Result so far: 14883.0
The remainder is 530 after subtracting 1935 from 2465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Advancing to step 8:
5300 divided by 645 is 8 with a remainder of 140.
The number 8 becomes the next digit in our result. 
Result so far: 14883.8
If we subtract 5160 from 5300, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 9:
645 goes into 1400 2 times with a remainder of 110.
Use 2 as the next digit of our solution. 
Result so far: 14883.82
Deduct 1290 from 1400 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 10:
When dividing 1100 by 645, we get 1 with a remainder of 455.
Write down 1 as next digit of the result. 
Result so far: 14883.821
If we subtract 645 from 1100, we get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Moving on to step 11:
When dividing 4550 by 645, we get 7 with a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 14883.8217
Subtract 4515 from 4550 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 12:
If we divide 350 by 645, we get 0 and a remainder of 350.
Put 0 as the next digit of the answer. 
Result so far: 14883.8217
Deduct 0 from 350 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 13:
When dividing 3500 by 645, we get 5 with a remainder of 275.
Use 5 as the next digit of our solution. 
Result so far: 14883.821705
If we take 3225 away from 3500, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Advancing to step 14:
645 can be fit into 2750 4 times, resulting in a remainder of 170.
Record the quotient 4 as the next digit in the result. 
Result so far: 14883.8217054
Subtracting 2580 from 2750 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 15:
645 goes into 1700 2 times with a remainder of 410.
Record the quotient 2 as the next digit in the result. 
Result so far: 14883.82170542
If we take 1290 away from 1700, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

The final outcome is 14883.82170542, with a leftover of 4.1e-07.
