We're dividing 644154 by 65 
We're looking to find how many times 65 goes into 644154.

Moving on to step 1:
65 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 65

Going ahead to step 2:
If we divide 64 by 65, we get 0 and a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Include the next digit (4) from the dividend after 64, then repeat: 644 / 65

On to step 3:
644 divided by 65 is 9 with a remainder of 59.
The next digit of our result is 9. 
Result so far: 9.0
If we take 585 away from 644, we end up with 59.
Include the next digit (1) from the dividend after 59, then repeat: 591 / 65

On to step 4:
591 divided by 65 is 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
The remainder is 6 after subtracting 585 from 591.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 65

Going ahead to step 5:
When dividing 65 by 65, we get 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 991.0
If we subtract 65 from 65, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 65

Let's proceed to step 6:
65 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 9910.0
Deduct 0 from 4 and we're left 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.

Step 7:
The number 65 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 9910.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
65 goes into 400 6 times with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 9910.06
Subtract 390 from 400 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
65 goes into 100 1 times with a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 9910.061
Deduct 65 from 100 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 10:
65 can be fit into 350 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 9910.0615
If we take 325 away from 350, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 11:
When dividing 250 by 65, we get 3 with a remainder of 55.
Write down 3 as next digit of the result. 
Result so far: 9910.06153
If we take 195 away from 250, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 12:
If we divide 550 by 65, we get 8 and a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 9910.061538
Subtracting 520 from 550 leaves us 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.

On to step 13:
300 divided by 65 is 4 with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 9910.0615384
Subtracting 260 from 300 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.

Advancing to step 14:
65 goes into 400 6 times with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 9910.06153846
Subtracting 390 from 400 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 9910.06153846 with a remainder of 1e-08.
